MH2G Display HP Hack is actually not really a Cheat.
Depending on the Version only 4 to 8 Lines are actually usefull CWCheat Codes.
The rest is ASM (Assembler) Code that gets dumped in a place in RAM
The hack works by hijacking a jump instruction in the game code.
It gets replaced with a jump instruction to the previously positioned ASM instructions.
In more detail:
The Game has 2 bytes that indicate if you press a certain Button Combination.
If you press L+Select in game, the bytes change to 0101
If you press R+Select in game, the same bytes change to 0201
With a 16bitEqual Compare-CWCheatCode the hack uses CWCheat Codes to monitor this adress.
If the conditions are met it then replaces the jump instruction.
Therefore code injection takes place and the game executes the custom code.
A real awesome & creative use of CWCheats!
