CwCheat Support

im running PPSSPP 0.9.1 For the windows.
So heres the problem, some the cheats doesn't work with the game, even if that was only a pretty basic cheat (Max Money), but the more complex cheat like (EXP Multiplier) works.

Game ID:
_S NPJH-50681
_G SD GUNDAM GGENERATION OVER WORLD

Heres the code that doesn't work:

_C0 CAPITAL 9999999
_L 0x211D0600 0x0098967

I don't play that game myself, but regardless of the game, there's one thing about that cheat code which strikes me as very odd indeed.

The hex value 0x0098967 only has 7 hex digits, whereas the standard CwCheat format requires 8. And the numerical value is equivalent to the decimal value 624999, not the value 9,999,999 as claimed in the cheat title. That value should have the hex encoding 0x0098967F, so it seems to me that the value was entered with the correct final digit gone missing...

Anyone creating a cheat code with that kind of typo ruining the data part may also have made a similar (but inherently worse) mistake in the address part. And poking the wrong address will obviously not have the intended effect.

It's also possible that the address is correct, but that the PPSSPP cheat engine implementation rejects the cheat as invalid, when it uses the wrong number of digits for the data part. (I'm not sure how the implementation works currently, but if I had coded it then it would reject illegal values.)

So I recommend that you try it with the full 8 digit hex value 0x0098967F.

_C0 Unit EXP x512
_L 0x20052024 0x0a200800
_L 0x20052028 0x92b60032
_L 0x20002000 0x3c1708bd
_L 0x20002004 0x0a21480b
_L 0x20002008 0x00118A40

Actually that should be more 'iffy' in how it works, especially if you turn it off and on in-game, since these patches reside in the program code section of memory which is treated differently by the PPSSPP emulation engine (JIT-compiled when needed for emulation, but not for each cheat patch cycle, as that would make the emulator slow).

Quote:So my question is:
1. Is this problem only occured to me? or other people managed to run this fine on their PPSSPP?
2. Are this code only be able to run on real PSP?

Others will have to reply to those questions, as I don't have that game.
And for game specific issues like that you need to look for game specific threads.

Quote:3. Can PPSSPP supports all CWcheat codes?

Not all. At least not yet.

But that should not be a factor in the problem you have, since all cheat code lines you presented use only one and the same basic cheat opcode, that being "0x2aaaaaaa" with the a's representing the patch address.

And that cheat opcode is definitely fully implemented.
