CheatDevice v0.8 for LCS

[edisoncarter]

I confirmed it's not just UK but US too on firmware 2.5. You can't let it autoload cheatdevice during the game boot if you have firmware 2.5 or it'll either crash or not come up at all. If it doesn't crash, the menu doesn't show up and then it won't load from then on until you reload the game.

 

You see, this is why I don't want to take on yet another firmware version. This is already more variations than I care to test. I've got 8 now:

US 2.0 Boot

US 2.0 Load

UK 2.0 Boot

UK 2.0 Load

US 2.5 Boot

US 2.5 Load

UK 2.5 Boot

UK 2.5 Load

Edison you bloody legend, this is so awesome, now i can have more fun then ever.

 

This has got to be the best thing since the psp.

 

Keep it up edison.

[dommox]

edison could you post the method you used to decrypt/modify the data.bin file

[optimolife]

I think all the people who are crying about 2.6 not working or whatever other reason that you can't run the cheat, need to go out and buy a version of the PSP and a version of the game that work with the cheats that Edison has already made, and not harrass him about tailoring a version just for you...

 

This man has worked hard enough already and if you're so dying to use his cheats, then instead of telling him to buy a new PSP, maybe you're the ones who should suck it up and do what you have to do to get a version of the PSP and game that are compatible with what's already out. Just my 2 cents.

 

I'll say it again, thanks Edison for all the work you put into this.

 

PS And people should stop begging for his method, 100 people have already asked and he hasn't revealed it, It's kinda obvious he doesn't want to tell the world how he did it ---at least just yet. The man is taking very good care of the GTA community and no one should be complaining.

He discusses it briefly at the ps2dev forums but he's been tight-lipped about anything else (including his methods for automatically resolving NIDs, the LCS exploit, etc). Too bad really, as this would be very useful info for extending homebrew to 2.50+ without facilitating piracy.

[ADePSP]

Here are a couple of good locations not on edisons list...

 

Portland

 

Capital Autos - Car Salesman Missions : 1199.59, -80.08, 11.94

 

Stanton Island

 

Hot Cogs - Bike Saleman Missions : -83.07, -474.61, 16.16

 

Hospital Roof - Fantastic Sniper and Rocket Launcher Position for Total Carnage : 188.82, -19.65, 22.70

[cjpluss]

Although I will never get to use the device (My 1st PSP with 2.0 broke so I have to use my newer 2.6 PSP), I've now finally seen it in action on my friends PSP and Im truly amazed. Don't bother trying with 2.6 just to please us select few, keep working on 2.0 and 2.5. Can't wait to see what other things you can do with this. You deserve many cookies X100

[jamxd]

Am I the only one who sees the money making potential for edison?

Advertising revenue perhaps?

Sell the secret?

I mean you need to compensate yourself for your time and buying psps etc.

[ADePSP]

Yeah, he should release the next version as shareware I think... It's only fair...

I think the reason why so many people are askign for the method is because this appears to be

something that was thought to be impossible on a 2.0+ machine.

 

The running of unsigned code. People are messing abotu with messy crashes and exploits and overflows just trying to

get a simple "hello world" program to run and EC seems to have jsut gone and got complete code working seemlessly then

moves on to get it to work for all versions.

 

I for one am waiting/hoping for a 2.01 ->1.5 downgrader and when I saw this cheat in action thought yes! here we go.

I mean people are wetting themselfs withjoy when a picture crashes their psp!

 

But hey, it's his code and technique. But I would hope that he plans to release to the comunity how he has achieved this

at some point in the future.

 

Just my 2p

[gamerzworld]

Rockstar should've done a lot of things.

 

If they didn't want helis in the game, they should've removed the helicopter.

 

They just directly ported the GTA: Vice City engine, skins and all, to the PSP, and just put the GTA III models, with a few tweaks, and new models, on there.

 

I thought they were going to use the latest driving engine, that came with San Andreas.

 

You know how I knew they didn't?

 

If your door is open, and you go fast enough, and swerve, it should close. Like it did in SA. But Vice City didn't have that.

 

Then I saw this cheat trainer, that can spawn the VC police helicopter.

Your forgetting that the game is on PSP which is almost as powerful as a PS2, it doesn't use the Vice engine it uses a severly modified renderware engine to deal with the lacking hardware. As I've said before atleast we got a new game instead of a direct port of GTA3. Sure its still Liberty City but its a new story with new characters and a late nineties version of Liberty which is slightly different.

 

Those stating new features etc remember that Edison can only do stuff with data that is already in the game he can't add stuff so making the dodo move probably isn't possible since we can't change the handling line through a save game, same for parachutes, jetpack, and even crouching.

The game is not even built on Renderware. R* made there own for the game.

[reecemac]

just noticed us vers is up to f now, what additions since d? i would check but have the uk version. nice work edison, been admiring your work since sa.

 

Happy Birthday gamerzworld

MPORTANT NOTE for all users with firmware 2.5:

It looks like CheatDevice is crashing if it autoloads during the game bootup on firmware 2.5. If you have firmware 2.5, you'll need to boot the game by having a more recent save on the card so it loads that first, or with the memory card out so it starts a new game. The US version may load without crashing but then the menu won't come up, and still won't come up until you restart the game.

hummm Works just fine for me No crashes here. It even atuoloads fine.

Agreed. But on the other hand, we can figure it out easily enough; just need to repeat his work on figuring out how the savedata functions work with the new save format (some disassembly of gta's boot.bin should make this clear), decrypt his save, and search for the MIPS code.

I guess the dynamic syscall fixup must have sounded like a bigger deal than it is. All it does is adjust the syscalls to match what the game is using.

 

This wasn't one of those hacks where you spend a long time searching but once you've found the trick and you know just what bits to flip, you could do it again in a minute, and you could tell someone else and they could go straight to the same place. It's not describable as a "just do this", or at least not one you're going to like. There's no silver bullet trick you're missing out on. I rolled up my sleeves and wrote a program on the PSP to use the PSP's own libraries to decrypt and encrypt the savefile. I don't know what the encryption or the checksum is and I don't need to. It was a long, arduous programming project, and I can't recommend anyone go through that again.

 

I don't want to make any money off this. It's impossible for AR, GS or CB to make a cheat disk for the PSP, so this time you get a free cheat device.

 

I went through a few versions on the US version, up to 0.1f, getting it to not quietly fail when booting on 2.5. It's better if it crashes than to quietly fail and then the menu doesn't come up and will not come up from then on even if you load the file again. That would just add more confusion to have a new, less obvious failure mode. If you downloaded 0.1e, don't use it, get 0.1f.

[liberty city mob]

i allready cheat when i play gta, would using this make a big differance if i save after using this?. if i only use health and wanted. im done with story mode and im just doing races, jumps, and odd jobs.

 

P.S. after i try spawning a few vehicles, it starts loading player skins, and after I load a few skins, i can only move forword.

Personally, I have been saving after using CheatDevice and it's been fine for me. All the driving to set up missions was getting too long and frustrating, so I've been using a pre-release teleport feature to get around. It takes out an unfun frustrating part of the game and lets you get straight to the missions. They were getting docked for all the far away mission pickups in the reviews.

I have a list of some Coordinates for you in a bit

When Are You Goin To Make One That Works For Firmware 2.60

[warrens467]

shut up about 2.6!!!

 

can you actually fly the dodo? my one dosent move!

[foodevl]

Thanks for the reply.

 

I guess the dynamic syscall fixup must have sounded like a bigger deal than it is.  All it does is adjust the syscalls to match what the game is using.

Oh, I understand. I suppose the lack of known syscalls for 2.60 is then one of the problems of getting it to work there.

 

This wasn't one of those hacks where you spend a long time searching but once you've found the trick and you know just what bits to flip, you could do it again in a minute, and you could tell someone else and they could go straight to the same place.

Agreed. However, the original TIFF exploit for 2.00 was the same way, and there was an excellent in-between solution where it simply loaded a file from the memory stick and executed that at some fixed location in memory, which provides a great tool for further experimentation. Certainly we would need something like Fanjita's excxellent Eboot work before it's a silver bullet for homebrew.

 

I rolled up my sleeves and wrote a program on the PSP to use the PSP's own libraries to decrypt and encrypt the savefile.

Based on Shine's savedatatool, correct? Would you be willing to share the solution to the problems you were having with sceUtilitySavedataInitStart?

[gamerzworld]

Heres what I found before my game crashed....

Island 3 Save House: -825.79, 304.32, 40.02

Island 3 Pontiac: -908.84, 355.01, 38.61

Island 3 Hospital-Police: -1289.88, -56.79, 58.71

Island 2 Inside the football Feild: -0.75, -85.45, 16.16

Island 2 Ferry Dock: 187.28, 220.98, 11.70

Island 2 Subway: 117.55, -1555.51, 26.15

Island 2 Plaza: 42.16, -1053.33, 26.01

 

Also is this a bad thing

WARNING: Failed to allocate memory block. Your game may crash if you proceed. Press L1+R1+Up to exit

BUT it still works

When i load the save file to my PSP it says corrupted data. SOMEONE PLEASE HELP!!!!!!!! hELP1!!!!!!!!!1 EDISON!!!!

[-DeMoN-]

edison, possible to make it teleport to a marked point on your map? Like back in the old SA.

 

And also, would you be willing to release that program you made? If not, I understand, there are just other games I would love to try to play around with.

It should have worked for 2.6 also. I don't hardcode the syscalls. Whatever they get set to for the game, I use the same thing. It's probably something else failing on 2.6.

No, not based on Shine's tool. Tried that. I did share the problems I had with sceUtilitySavedataInitStart at ps2dev.org. I couldn't get sceUtilitySavedataInitStart to work on 2.0.
