Sega Game Gear PAR Codes

[Whipon]

I appreciate what you've taught me very much!

I was able to fully follow the guide.
I completely understand everything, up until the actual ASM stuff.
I mean, I understand that it's just loading a value and writing it to that address.
But how do you know the proper way to modify it, like, where does the 3A come from?

I suppose my understanding will only improve with time, but still, thanks very much!

You're welcome .
Glad to know you understood everything.
About how to guess what value is good to replace another one, you'll need a list of opcodes to do that.
The Game Genie Code Converter has a full list of the Z80 opcodes, and its HEX values.
I attach a Z80 opcode reference doc so you can have a look at it.
You just have to use common sense. Once you've found a good combination, you can use it later to hack another game.

Hey guys,

thanks a lot for all of the great codes.

A bit o/t here: is there a way to convert these so I can patch my rom permanently with codes?

If you want to do it manually, paste in the 'Genie code into the 'Game Genie Code Converter' app, and it'll spit out it's ROM address for you.
Open the ROM with a hex editor, and just use Go To Address.

Yes, I was trying to load the Master System roms by accident. The codes work great thanks.
