Q: 
How do you get into the walled off places in San Andreas? I have tried looking all over for secret little entrances but can't do it. 
Submitted by finch 

Q: 
I recently got the file/program that alledgedly lets you save your game, but was having trouble getting it to work. Has anyone used it successfully, and if so how. The "tutor" that comes with it is rather vague it seems. I'd much prefer to be able to save my games part way through in case my computer crashes.

Q: 
In the Playstation version is it possible to get 1) the boat 2) the fire truck 3) the train as I have seen none of these even when I wait by burning cars and buildings. The boat popped up in Liberty City when 
collecting ransom money but I am now on San Andreas part two and have seen no sign of it. 
Submitted by templetonshay 

A: 
The answers to your questions are as follows: 

1) No, As far as I know you can't get the boat without cheating. 
2) Yes, there is a mission where you need to steal one of these. 
3) Yes, but you need the patients of a saint, to hang around all day  
waiting for one of these to turn up.

Q: 
I was wondering if there was any secret involving the cars in Vice City that self-destruct. Are they just traps and weapons or can they be used to open secrets? 
Submitted by Putzmeister 

A: 
I'm not 100% sure on this, but as far as the mission.ini file seems to read, these are just designed to blow up and make your life harder.  The one I particularly liked, mind you, was the cop car you steal and two radio-controlled bomb-cars come after you (somewhere just west of Vice Beach :)

A: 
I know it's noddy - but once you've got the pager up and typed your message, have you pressed return to send it?  (You can tell I've done too much tech support recently).  The pager will only accept a maximum length string as well, which is reasonably short, but if you type quickly you don't notice this until the scrolling catches up.

Q: 
I was wondering what do you do in a Cannonball multiplayer game? I have heard it mentioned but I do not know what it is, I only  have the demo, but the part that interest me most about games is their  multiplayer capabilities. What are the multiplayer options in Grand Theft Auto? 
Submitted by Dustin Ampania 

A: 
The multiplayer options are available in each of the 3 cities. They are as follows: 
1.) Deathmatch 
2.) Cannonball 1 
3.) Cannonball 2 
4.) Cannonball 3 
The Cannonballs are merely races between players.  Various checkpoints are set up and players race to each one as they follow the arrow directing them.  The winner is the one who reaches the final checkpoint.

Q:   
Is there a way to get 1,000,000 in the liberty city demo? 
Submitted by Tom   

A:   
Yes, Tom, you can easily get over 10,000,000 pts in the Liberty City Demo. The procedure is outlined on the "Tips & Tricks" page. Just "stack" cars side by side (at least 20, more recommended), and gun down the first one.  1,000,000 is the target score in the demo, but this can be changed in the mission.ini file to something considerably less.  As yet, I haven't found anything special that happens when the target score is met.  In the full version, you just proceed to the next level.  The demo doesn't have a next level.

The Fire Engine doesn't shoot water or anything, and you can't even move the turret/hose 
Submitted by Ringo

A:      
Tank only shoots during a mission e.g. Kill Frenzy. Once completed it loses its ability to shoot, which is done by hitting the fire key (Ctrl). It needs no reloading. 
Submitted by Ringo

A: 
Well, POOT, the boat is rather easy to find.  Just start off, take two lefts, a right, then the second right, and now you should be in front of your mission.ini file.  Just change the Andreas Medium starting vehicle (andreas medium line 84) from 19 to 13.  Once this is done start the game and choose Mandarin Mayhem and there it is...and remember, "Don't be a pain in the boat!" 
Submitted by Ted 

A:  
You can't get the boat.

It is 1 million for the first level, 2 million for the second (Still in Liberty City) and 2 million for the next (In San Andreas). You can find out how many you need by pausing (F6) and waiting till the message pops up. 
Submitted By Ringo

A:      
(In regards to - "And when you accumulate enough credits do you move on to the next level??")      
It's 1 million points. At least, that is according to what a friend of mine told me, who has played the game extensively. 
Submitted by Sir Beast     

A:     
It's  1,000,000 points.  It tells you the goal when you pause the game  (F6) 
Submitted by Paul     

A:     
When you get 1,000,000 you get a message that says to meet a guy and your arrow turns red. Follow the arrow and meet with this guy. Then it breaks to an animation. Presto, it saved the game and on to the next series of missions.

GTA will be released in the US in February for PC and in April for the Playstation.  In the UK, GTA has been found at PC World, WH Smiths, Virgin Megastore, and HMV.  I've also received word that it is available in Denmark.  I'm guessing that it is available in the rest of Europe as well.  I still have not gotten any reports of availability in Canada or anywhere else for that matter.

Q:  
In the first chapter of San Andreas when you have to collect the premiums, I find two secret Love Wagons in the car parks, when I get into the first one & blow up a few cars a Fire Engine comes.  When I try to blow this up the game sometimes quits.  Why does this happen?

Q: 
Call me sad, but I've been having problems finishing Chapter 2 in Liberty City. What's the trick when you get to the bosses office after obtaining the necessary 2 million points? 
Submitted by Big Jon 

A: 
Sometimes, the game jacks up and when you go into the garage, it just 
lets you walk around with the little arrow going crazy, and it never 
works.  It's a glitch.   Try it again I hate that! 
Submitted by Ted

A: 
There is a way to do this, it always works for me. All you need is a machine gun and a getaway car to sprint to the autoshop.  When you see the four guys standing there aim and shoot 3 of them, the other one will crap his pants and run off. Chase him, avoiding arrest and when you catch him beat him up. That should solve your problems. He will reveal the rest of the mission. 
Good Luck.

Reading the sign in San Andreas:  

Once you read the sign that's over the ramp in the bottom left corner, you'll find a secret door has opened elsewhere on the level, giving access to a tank kill frenzy.  Where it is... I'm not telling.

Q: 
Help!!! I was wondering if anyone knows how to set up an IPX game or what a network socket number is.  I can get it to work just fine in Windows over TCP/IP but DOS is faster and I want to know how to set up the IPX. 
Submitted by AcmexOne 

A: 
I'm not going to go into a lot of detail on this, because it depends on your system, but basically it goes something like this.  You need DOS ipx drivers for your network card - as an example mine are called ipxodi.com (the IPX/ODI protocol program), lsl.com (links support layer), and ne2000.com (The ne2000-compatible card stuff).  Basically, you drop out of Windows into DOS-mode (otherwise your different network protocols shoot each other in the foot), run the link support layer, run your card program, and then run the protocol you wish to use.  Then, run GTA 

A couple of notes: 
 

1.  This isn't the only way to do it, just a common way I've seen. 
2.  The programs depend on what DOS network support you want, and more importantly, depend on which network card you've got. 
3.  You'll need to set up a config file so all your computers are running the same protocol (Ethernet_802.3 for example). 
4.  Your card drivers should come with the card, or better yet, get the lot off the internet. 
5.  I don't think socket number is important unless more than one game 
is running on the same network.  Just leave it as it is.

Q: 
I can't get GTA working over a modem.  It disconnects me whenever I try and connect with a mate.  I'm in dos, I enter all the info, then "join network", he then hears his phone ring and his modem answers it, then after a while it says failed-disconnecting and using Win95 doesn't help.  The thing is, we have no problems playing duke3d this way.

Q: 
I want to play GTA through ipx because i have found a way to do it. You can only run it through DOS. When i run GTA in dos there are no network options available.  When i try to configure ipx it gives me a message saying choose a number form 0-65400, which number to i pick?? and how to I configure ipx properly, how does it all work..?? 
Submitted by Scott 

Q: 
I am trying to get an IPX-game running, but even though the network works fine with games as duke3d or descent, GTA doesn't find an opponent. Both machines just keep waiting (of course one computer starts the games and the other tries to join it). I don't know if this is a problem concerning the network configuration (by the way: what is the socket number?), but the netware IPX software seems to be configured perfectly -- even my netware server works fine. 
Submitted by Markus Schneider 

Q: 
After about 5 minutes of playing the modem game disconnects.  As soon as it connects us we can play for about 5 minutes, the only thing is that it runs alot slower than normal.  Also just before it disconnects us it pauses for about 10 seconds then says the connection was lost.

Q: 
How do you set up a multiplayer game using the modem?  I have tried the dos version and GTA could not find my modem.  The windows version answers the call but returns with no sessions available.  I have directx5 as well as the directplay patch.  Would it be possible to set up dial up server (microsoft plus) to use tcp/ip and make gta think you are playing on the internet. If this could be done it would be a lot faster.

Q: 
I have been trying to play the windows game of GTA but it always gives me an error saying "Error:  Cannot find a suitable display mode" 

I have that same exact problem and I tried both of the answers neither worked.  I am running a 200 pro with 32mb's of ram s3 virge with 4mb video and a pure3d 3dfx card.  I have directx5 installed I removed it and reinstalled it... still I got the error msg.  I went to the dos version (the one I usually play at) and set the resolution to 640x480x32.  I went back and tried to run the windows version still nothing.

In my networking class we have noticed that big drop in framerates when you have a four player game with pentiums. The is also a large performance drop if even one 486 is playing, even if it is only a two person game.  
NOTE: If you can, use the DOS version of GTA, even in Windows 95, because it runs much faster.

A: 
Your desktop is flickering with DirectX 5.0 installed because Micro$oft's DirectX hasn't installed, for want of a better word, an 'accurate' enough driver for your card.  I had the same problem 
installing Tomb Raider II - it automatically ran DirectX and changed my display driver without asking, despite my original driver running fine with TR2.  The only viable solution is either (a) get the most up to date driver for your card and install it after DirectX or (b) wait for a better version of DirectX *hint of irony*.  If the drivers for your card are the ones it came with the chances are there's a far more up to date version on their web site.

The problem could be a monitor that is not compatible with the resolution that GTA is trying to run. Ages ago, before I had my SVGA monitor... hehe... whenever I tried to run an SVGA game, I got the black-dot screen thang. I think it's your monitor.

Q: 
I have been playing GTA with some friends recently using IPX and TCP/IP on a 10mbs Win95 network. Out of all the games I have ever played, it runs so slow! I was looking for any suggestions or info if it is bad coding or something else? 
Submitted by Jeremy 

A: 
Play DOS version GTA on IPX, even if you're in Win95. Also, you take a large performance loss if you have: 
• A 486 playing
• More than three people playing.
I have noted on my GTA games that no matter what kind of Pentium you have, if there is more than three, framerate drops are pretty large. I hope this helps. 
Submitted by Michael Ebata

A:  
If GTA is giving you an "Error: Cannot find a suitable display mode", do this following: Make sure you have the latest version of DirectX installed, and go into the directx folder  
(usually C:\Program Files\Directx). From there, go into the setup directory. In that directory you should find a file called "Dxtool.exe". Double-click on it. At the very bottom there is a box that says next to it "Use DirectDraw Hardware Acceleration". Make sure this is checked. If that doesn't work, try messing around with the other settings in the directx tools. NOTE: If you enable DirectDraw Hardware Acceleration and have a video card with the NVidia chipset (RIVA), make sure to disable it when you are done with the game, or it may cause problems with other applications. 
Submitted by Absolute0 

A: 
Windows will not run at anything lower than the resolution of 600 X 400. 
Therefore If you want to see GTA on the screen you have to go through the 
DOS High GTA version and change it and then you can go back and play it 
through Windows. 

Warning: This then becomes very slow and has little of the playabiltiy that 
the 300 X 200 Version had. BUY MORE RAM!

Q:   
GTA flashes in High-res mode in Windows!  anyone know what causes that? 
Submitted by fee  

A:  
Sometimes, if your Windows resolution is Bigger or Different than the 640x480 or 600x800 that Grand Theft Auto uses, Both resolutions have to be supported. My workaround suggestion would be to either switch Windows to 640x480 / 800x600 (depending on your GTA settings), or to run GTA through DOS. I experienced the same problems with other DOS games which used different resolutions and a change in the  Windows resolution fixed it.  This tip will only work with the Dos Version as I have only tested the Demo for DOS. I imagine that Windows 95 uses DirectX, but I don't know.

Q:      
"I still can't find out how to save a game. In a FAQ I picked up it said you could save after each mission completed but what is the process for doing so,  which keys do I press etc and once saved how do I load it up again! 
Submitted by Nathan      

A:      
The character you choose (E.g. Bubba, Cluadia, UUUUUUULRIKAKAKAKAKAKA) is your save game. It is done automatically after the level is complete. When you progress to a new level, only this character is able to play (Unless the previous level has been completed.) I expect this is for the end scene when the game is completed.

BUG: 
Can't remember which city it was, but it was the mission in which you have to steal the reporter/journalist's car. The police were after me at the time, I found the car and got in. A policeman ran towards the car and I tried to get out at roughly the same time he tried to open the door to drag me out. Anyway, I got out of the car and he climbed in and shut the door! I couldn't get him out and he wouldn't drive anywhere so I just shot the car, laughed and failed the mission. 
Submitted by Dave 

BUG: 
I've recently found an... interesting bug, to say the least. If you hit the police while going fast with your car, they of course chase you. But if you just tap them, they don't care. Therefore you can push them through the whole level, and even push them off a bridge, or something like that. But thats not the bug... the bug is that if you push them into water, it seems that they keep driving even under water! I'm not sure if thats it, but it looks like they're creating some sort of whirlpool. 
Submitted by Absolute0 

BUG: 
I was getting chased by a police car over a bridge and he stopped and got out, i tried to hit his car to run him over, but my car went underneath his.  Then the same happened with other vehicles. What the hell is goin on?? 
Submitted by Scott 

BUG: 
First, I was riding a superbike in San Andreas and, employing a tip I read on a GTA site, I was holding the button for punching while I was riding.  I got hit by a Penetrator, and, while the bike didn't fall, I was knocked off.  I tried to steal the Penetrator, but when I hit enter, I climbed off the bike!  To my surprise, I was walking around AND controlling the Penetrator.  Unfortunately, I ran myself over before I got to have much fun :( 

Next, I was trying to complete missions in Vice City and I noticed that the car I had to steal (the one with Deever's kids) was on fire. It wasn't charred or damaged, and it drove just fine, but it was engulfed  
in flame.  In fact, for the next two or three missions, all of the mission car were on fire.  The same thing has happened to me on the San Andreas mission where you have to kill a dry cleaner.  The only cause I can come up with is that it had something to do with my ejecting the CD. 

Third, and not to mention my favorite, is most easily accomplished with a Beast GTS, but any car will work.  First, you have to park a car (or bus, tanker, even a tank :) about halfway off a ledge.  Then, jump off the ledge and fire a rocket at the wall or cliff below the car.  It seems to work best if you can hit slightly to the west of the car.  As you expect, when the rocket hits the wall, the explosion blows the car to pieces.  But then something weird happens.  The car just keep blowing up.  And other cars seem to be impervious to these explosions. They do set pedestrians ablaze, though, if they are close enough.  My guess is that the chain reaction explosion has something to do with the way the game engine interprets varying heights, and the car hanging off the edge really confuses it. This seems to work with any car, even oversized vehicles, which are a LOT more fun.  Good for about 100 explosions, then you need to fire another rocket. 
Submitted by Putzmeister 

BUG: 
Many a time in GTA I have got close to a wall (eg when going down a tight alley way) and have become totally stuck in it, I cant reverse or go forward.  The only option I have is to get out, normally this is not a problem (Just steal another car), but when its a mission car its a bit annoying 
Submitted by Mark B 

SOLUTION: 
I've had this happen several times with special mission cars, and the only way I was able finish the mission was to get out, get a truck, and ram the car "out" of the wall, and get back in.  The car takes quite a bit of damage this way, a real problem when you have to escape from 
cops later, but it's my only solution.

BUG: 
Mental sent this message to DMA.  DMA's reply is just below this message.  
I think Ive found a bug in your lovely game... I've tried it on two copys, still happens.  When you pinch the pickup, after a while, that anoying country and western music starts jumping. I tried cleaning the CD, but I bought my own copy yesterday, And it happens on that, too.  

For your info, I'm running.......... 

P200MMX 
64Mb Ram 
Hercules Stingray 128 Voodoo rush chipset

Submitted by Mental 

SOLUTION: 
Sorry to hear about your problem. This is something a handful of people have mentioned. We're just using standard CD Audio code (ie just sending an instruction to start playing at track 'x'), so there's nothing in the GTA code which could be causing the glitch.

SOLUTION: 
I've run into the same thing several times, mainly with parking cars in driveways.  One solution I found was to park the car on the arrow, then get out.  Sometimes this triggers it, sometimes driving around again, parking and getting out triggers it.  And sometimes, parking just off the arrow and getting out triggers it.  And sometimes drinking half a bottle of whisky means it doesn't matter any more :)

It all happened in first city, mission 2, with "iamthe..." cheat enabled. 

As usual I fu*ked up some missions and was left out of work - so no missions until I found a secret car... I was cruizing around with the top down and was collecting guns and trying to find a car with a mission.  When I had 99 ammunition for both pistol and machine gun, I decided to "make some noise!" - that cruizin' got boring... 

I started to shooting all the cars I could see. In the first intersection I shot at and made explode about 6 cars, and accidentally also my own car :-) Then I was running along the bridge 
and made every (ok - few got away... :-) car that passed blow up. That included the paramedics and fire brigade... But this fun didn't continue for long... 

I ran out of moving cars!!! 

I had bullets left in my pistol, but no cars to shoot at! The only cars I was able to find were the few, parking around the city.  But finding them wasn't easy - go try yourself running on foot on wide 
road... As the game "zooms in" - you cannot see well, if there is any cars parked alongside that road... 

IMHO: This bug probably happened, because I shot all the Fire Brigade Trucks and all the ambulances before in that game... and There was nobody to clean up the mess after me.

BUG: 
When playing GTA on San Andreas, a potential bug popped up. I  was in a four cop police chase when I got stuck against a wall and a two police cars piled into the back of me. All three cars blew up and my points suddenly went sky high! The points went to 999999999 (one short of 1 billion!) and I simply went to the end of mission dude.  Has anyone else seen this? 
Submitted by Ryan Lewis 

BUG: 
Regarding the second tip on your site "to net millions of dollars in a short amount of time": I 
tried it and, maybe I overdid it, but anyway my money started growing fast as the next car exploded, grew up to nine digits and then the first digit continued the turn around, like it was outta control.  I thought ok, let's continue the game.  But, about two hours (!) and some four missions later, when I had to go to a bomb shop, the guy said "Come back when you have money!"  BUG!!!  So watch out with this one. Better stick to the factory cheats provided on the site. 
Submitted by Davy 

Solution: 
"my money started growing fast as the next car exploded, grew up to nine digits and then the first digit continued the turn around," and later you don't have enough money any more. 

Well, a possible reason is that the score has "wrapped around" and become negative. This could happen if it were kept in a 32-bit signed integer variable. These variables can hold numbers from -2,147,483,648 to 2,147,483,647. The number 2147483647 + 1 can be computed, but will be interpreted as -2147483646. You don't notice this because your score grew so fast and you can't see the billion digit; in addition, GTA is obviously not prepared to display negative money ;-) 

Bug Fix: Ask DMA to release a patch that checks for overflow when the score is increased. 

Workaround 1: Keep track of the unseen digit and don't exceed $2,147,483,647. Find out how many cars are safe to blow up. 

Workaround 2: Blow up some more cars and make the score positive again (not tested ;-) 

Workaround 3: Give away some money, have it wrap around the other way and get a really big amount again 
Submitted by Michael Mendelsohn

SOLUTION: 
I have an addition to your posted bug concerning  stacking cars for points:  I too have noticed that the vehicles dissappear  when trying to get a few dollars together to begin a game, so here's a  fix...  I go to a busy intersection and stop a car by  running out in front of it. Now I shoot a couple of holes in the hood and the  driver surrenders his car to me. I do this once on each side of the street in  order to block traffic. I continue to politely ask the drivers to hop out by  blasting their cars (careful not to whack one while they are exiting), and park  the car as needed. This does not alert the police, nor does it tip off the  emergency units. I can continue doing this untill the bullets run out. And when  I do blow them all up, I still don't hear any chattering from the  police

SOLUTION:  
Actually I think this is done on purpose... Every time an emergency vehicle drives by it will clear the roadway of empty vehicles so traffic can begin to flow again... My only solution is to   

1) never kill anyone while stacking cars because then an ambulance will come and clear any vehicles that aren't on your screen  

2) before beginning your demolition work do a test to figure out how many vehicles it takes to get the cops pissed enough to come after you...  Then when you begin to stack make sure you do it right next to a respray shop and just before you steal the car that would attract the cops take a run through the respray shop to clear your record... That way the cops will never come and you wont have to worry about cars disappearing.  You will of course have to do this every so often to keep clearing your record...  

3) never blow up any cars before your ready to blow up the whole stack, because blowing up a car would attract a fire engine which would also clear any cars that are off of your screen...

I had chosen the mission where you take the bike from the angels.  I decided it would be entertaining to drive in there with a car bomb, push the bike I needed to steal down the street some, and blow those guys up.  This worked fine, and I went to get on the bike.  The moment I pressed enter a police car came speeding up and hit the bike.  However, due to some quirk of timing, it registered that I was riding the bike even though the graphic of the bike showed it knocked over.  It was quite funny looking.  The bike was severely damaged after I was knocked off and got back on again, I don't know if this was due to riding it while knocked over or just everyday damage.

BUG:   
Imagine the scene:    

You're half way through a certain job, your car is about to explode due to all the misdoings you've been doing, so you get out and grab another car. To your surprise, it is a secret mission car, and you decide to do this one for know (You have no choice anyway). You finish that mission, and return back to the phones for a new job.    

But wait! Didn't I say you were half way threw a job!?!?!?!?!    

So you pick a phone and do this job, which at some point includes dropping a car off in a garage. You come up to the garage, drive in... but nothing happens!!!! You drive out, then in again, out, in, out ,in, out ,in, but it's still not working! So finally you drive in, stop and get out of the car, but you still do not progress to the next stage in the job. Bummer, so the only way to do it is to fail the mission, not an easy task sometimes.

In regards to - To your surprise, it is a secret mission car, and you decide to do this one for know (You have no choice anyway.)   

Get out while you still can, you have the choice! Just hit the "get out" key while the guy is asking you whether you want the mission!

Just a Kwik note about your GTA  mission problem.  DON'T wait for the guy to get out of his car, you have to shoot him whilst he is still in it......but you have to be quick because, as you say he does push your car.  I had the same problem but this worked okay for me!!
