Can a multiboot program (i.e. - one that I create) load an official cartridge and run it? Let me explain, I want to create a memory editor that I can access during gameplay via an unused button. This program will edit memory in real time. I just need to know if it is a lost cause or not. But, ANY help regarding this same topic would be greatly appreciated!!!
Thankx 4 your time.

A multiboot program can execute code on cartridges, but good luck getting back to your multiboot program! Real games are also guaranteed to overwrite the memory used by multiboot program.
Probably better off making a multiboot savegame editor.

I think making a saved game editor will suit me better anyway. Thankx for the suggestion!

But what about the savegame checksums? Some games actually have those.

Can your code bl to the code within the ROM that creates a proper checksum?

Clearly the savegame editor needs to be able to create a valid checksum.

Sure, assuming you know where the code to create the checksum lives. I think you'd be better off reverse engineering the checksum algorithm.
