Code requests

[gamersin]

I've been trying for ages to make a code for Destruction Derby 2 to drive the cpu cars and an unlimited mass cheat for Driver 1.

I do believe possable for an unlimited mass code in Driver 1 bacause it's enabled for the gataway car in pursuit mode and I just need a code to enable it for the player car.

If anyone can help, thanks

The infinite mass thing couldn't be too tricky for Driver. You can easily run the game in an emulator with the Playstation Emulator Cheater plugin.

You can change the vehicles you are using. Different vehicles you use have different masses. Just keep changing vehicles with save states and checking for things that change. Wherever your health is located in memory, check the results closest to it because your vehicle's mass should be close to where your vehicle's health is.


I can't really remember if Driver 1 allowed you to use different vehicles though. It's been forever since I've played it. At the very least, you can check the addresses around your vehicle's health value, and something nearby should mess with your vehicle's mass.




As for the thing for Destruction Derby 2, I wouldn't know for sure.

My guess would be to use save states, one with 1 player and one with 2 players. You should check for differences between those two states. You might end up with a lot of results, but look for 1 byte results that have very small values. The correct result would most likely be a result that has values that change to only two different values that are less than 8. I would assume the value system might be something like:
00 = player 1
01 = player 2
02 or FF = CPU
or maybe even:
00 = CPU
01 = player 1
02 = player 2

If you are lucky enough to have something simple like that, check how far away that address is from player 2's health address. With luck, you can find the health of any vehicle and switch them to player 1 or whatever you want. But that is no guarantee. I'd assume you would need a ASM code.
