This game almost seems to have some sort of protection on its asm.

edit: Health moves, Its Asm is protected, yep going to be fun.lol

[dcx2]

What kind of ASM protection?

[Thomas83Lin]

Reads breaks on the asm, similiar to Ubisoft's Protection

example:

Health Read Break
801DD9D4: lwz r0,0(r3)

read break on 801DD9D4 triggers

modifying the Asm results in a crash.

[dcx2]

and if you change any of the ASM you get a crash?

[Thomas83Lin]

I edited my above post and yes modding the asm results in a crash.

[dcx2]

Yup, that's the same stuff Ubi used.  Starting with 801EE1FC:  48000015   bl   0x801ee210

infinite health [wiiztec]

however

[dcx2]

also, can someone fix the Infinite Health code. i'm not sure what the problem is, but it freezes the game when you choose a level.

That's the same thing Driver did.  It would look like it worked until you chose a level.

The ASM checksums probably don't run every frame, because they're too expensive.  The checksums more likely run during loading screens, where the latency can be hidden from the player.

Tested and works without crashing.

[dcx2]

Pointers and data writes for the win.  That's what most codes will have to be until I can finish a universal ASM patcher.

[Thomas83Lin]

Good Job Deathwolf.  :) yea pointers should work.

[Deathwolf]

Yeah pointer codes are working great. Of course it's still better if you guys could break the protection for ASM codes  :P

[g6flavor]

Some pointers might not work in all stages depends on which stage you grab the address from.
@Deathwolf, does your codes work in all stages?? ex. stage 3

update: codes doesn't work on Stage 3 (2nd half)

[Thomas83Lin]

Just a heads up for anyone testing their codes and noticing a freeze, the Code handlers main hook for VBI triggers the protection, in the challenge Room on the ship. Its possible it may trigger the protection in different areas of the game. but i haven't noticed it being triggered anywere else
