Well, first you make sure you do not use project 64 1.6. once that is out of the way, put the code in, and make sure that the code is enabled upon booting the game. If you know how to break point you can always go to the jump address and BP the opcode there, but thats only if you need to turn it on after the game has started
how do you use codes in nemu 64? sorry, ive only just got it, not really played much on it do you go to gameshark cheats, code names, put the code there. But i dont know what you put for the code value, please help
Ok, create a file in notepad, and paste the cheat in it. At the very top of the file, it must have:
[LEGEND OF DEBUG.Cheats] NumCheats=100
Note: LEGEND OF DEBUG may be LEGEND OF ZELDA, depending on what your ROM is called.
You must save this file as Cheats.ini
Make sure you tell it to save as all files not .txt.
Edit: to have the cheat on when the game starts in Nemu, you must pause it, then you press end emulation, then start emulation and the game should still be paused if you didn't close Nemu. Now enable the cheat, and unpause to start the game.
