This thread is to preserve and hopefully continue the 60 fps SEGA Dreamcast codes thread from the Assemblergames forum. All these 60 fps codebreaker codes posted were created by AG user "asasega" unless otherwise noted. I plan on formatting this thread so each game can be listed alphabetically and be directly linked to the code.

Maybe this will help people hack dreamcast games, in the absence of an emulator with debugging features.
There is a way to have breaking points and stepping through the code , seeing the registers etc using demul and cheat engine.
Use the following addresses with cheat engine, the addresses are valid for the latest demul (but is easy to find for other versions or any other emulator)

demul.exe+875E410 this is the PC register
demul.exe+875E3FC this is the PR register
demul.exe+875E2C0 this is R0 register, next to it are the rest of the registers
demul.exe+875E320 this is FR0 register, next to it are the rest of float registers
For accuracy switch demul CPU mode to interpreter.
Separate in notepad(or any other program) have the main elf disassembled obtained by any sh4 dissasemmblers available.

Example 1: if you simply want randomly to break and step, just set a write to the PC register, then just press F9(run in cheat engine) and see nicely the value of PC register increasing where it jumps etc

Example 2: let's say you find the ammo address for Biohazard, then set a write breakpoint to that adress and when the break happens just look at the PC register. The value of the PC is the exact location in the dreamcast elf where the write happened. Then if you just want to step further, set an additional writebreakpoint to the PC register, this way you can continue stepping from the initial ammo break that happened.

You just follow the PC values in the opened disassembled file.
These methods work for any emulator and cheat engine is nice because it is a value searcher and debugger in one

Pal version of LE MANS 24h you need to replace these values to run the game at 60 fps.

1. fps 159E16C8 offset track15.bin
2. timer fix 1586A2D4 offset track15.bin
3. the next 25 values
start 1586EDE4 offset track15.bin
end 15879250 offset track15.bin (inclusive)
just modify all occurrences of 0000F041, all 25 of them
Not sure if all are necessary, but surely is a combination of them because there is acceleration, traverse speed, distance etc. Don't have the patience to find the right combination. Anyway game works ok, could make the same laptimes as in 30fps.

Note: at 60fps the collision detection breaks, you can drive trough gates and walls you're not supposed too, and at the world boundaries you can fall from the track.
