How to make Lucky Tifa patch for psx?
« on: 2012-07-22 19:06:30 »
Lucky Tifa for psx. Think it's possible to do, just with Hex editor, but which file I should extract and modify. Can anyone tell me?  I know how to do it with artmoney in the psx version. I did not find the desired digits in Kernel.bin or Limitmenu.mnu. Sorry for my english.

What do you mean by 'Lucky Tifa' - do you mean that she always gets critical hits in her limit breaks?

Yup, I think he is referring to YAMP's Lucky Tifa.  As I recall, the changes needed are not so many (for PC anyway).  The Cait one would be far more problematic.

Yes, YAMP's Lucky Tifa,but for psx. I've already done this with artmoney.(I want do this without artmoney)
  digits for slots "yeah" = 02, for "hit" = 01, and for "miss" =00.
 first slot wheel   01 02 02 02 02 01 01 01 01 01 01 01 01 01 01 01, altogether 16 digits. But where this digits
 can be find in the FF7 CD, in the Kernel.bin or Limitmenu.mnu? And how to find this digits? I think Hex editor can help, but I could be wrong.
 P.S. game will crash if  in the first slot wheel stops on "miss", Tifa must always perform "Beat Rush"
 And I think that the Cait Sith patch (as for PC) does not need to do for the psx.

If any of the string you're looking for is assembler, you're out of luck on doing a simple digit search. The PSX runs on a MIPS R3000, whilst the PC version runs on the Intel x86 architecture. The instruction sets are completely different.

If you wanted to do this on PSX, you'd have to do a trace. I'm still not sure exactly what it is you want to do, though. I don't work with the PC version, so phrases like 'Lucky Tifa patch' don't mean anything to me.

I want to just change icons "miss" and "hit" to "yeah"  on the reels, and Tifa always gets critical hits in her limit breaks.
 Thanks for answer.

Hmm, I think the slots logic is handled in the battle.x, because that's where the other damage / attack algorithms and effects handlers are managed IIRC. You'd be best doing a trace; if you use the PSX emulator, you can exploit its in-built debugger for this.
