Every line of code inside a patch file follows a strict syntax structure. The emulator needs to know the type of patch, the memory address, and the value to inject.
To use these codes, you must create a text file named after your specific game CRC code (for FFXII IZJS, this is typically SLAI_250.77 or a specific hexadecimal string like 181E996C.pnach ).
