Anyone know how to make SNES game genie codes?

[MathUser]

I'm wanting to conquer that next. I'm just curious if anyone knows anything about this. For practice I was trying to make a Game genie code out of my enable pause code. Well, it's a 7e code (7E3AF201). So I tried using a breakpoint for it and then enabled that option on the cheat screen. So it snaps twice when i do that. These were the results.

$82/EFCB B2 0A LDA ($0A) [$7E:3B22] A:3B22 X:FB81 Y:0008 P:envmxdizc
$82/EFD0 92 0A STA ($0A) [$7E:3B22] A:0001 X:FB81 Y:0008 P:envmxdizc

So, um. I can use these to get the code that can be converted to game genie right?

what game? and you have all you need to try thenew GG code
82/EFCB B2 turns into 82EFCBB2 where the B2 is the ASM value wich is the LDA and the next line is the same explanation so to get results you will have to mess with the 2 las digits to see what kinda results you get.

Sorry, I posted it kinda late and didn't notice I forgot the games name. The game is called Ultimate Mortal Kombat 3

So the 0a isn't important? Cause it's posted twice in the same line.

I recall the SNES having a DB (Data Bank) and DP (Data Page) register. So when it executes LDA ($0A) it adds 0A to the value of the DP register to get the address it needs to obtain data from. Since LDA ($0A) affects 7E3AF2 then I'm guessing DB=7E and DP=3AE8.

cant remeber correctly but i think the (0A) is the value set at the ram adress or its the reference like the nes GG codes but isnt important here in the snes.

Don't know if you already hacked this yet or not, but this is what I would try with the info supplied:

Original code:
$82/EFCB B2 0A LDA ($0A) [$7E:3B22] A:3B22 X:FB81 Y:0008 P:envmxdizc
$82/EFD0 92 0A STA ($0A) [$7E:3B22] A:0001 X:FB81 Y:0008 P:envmxdizc

What I'd try, assuming you're trying to keep the memory address you listed from being set to 01h, is:

$82/EFD0 B2 0A LDA ($0A) [$7E:3B22] A:0001 X:FB81 Y:0008 P:envmxdizc

Instead of storing what is in the accumulator (A:0001) to the memory address, you'll load the accumulator with the current value at that memory address.
So if there is a zero there when the game is unpaused, and a one there when it's paused, this is probably how you'd negate that operation.

Blah, blah, blah

Oh yeah, the Game Genie code to try would be: 8432-3DD8

edit: just noticed you said you were setting up the breakpoint on the address: 7E3AF201
I would expect to have seen [$7E:3AF2] in the trace, not [$7E:3B22].
Sure the info is right?
