FearLess Cheat Engine

is this possible to do with emulators? i feel like its not or it would be super difficult to locate and do?

for instance i wanted this for monster hunter gen Ult on Ryujinx but editing memory isnt my forte, so before i get into it i was wondering if something like this would even be possible.

you have to understand the emulator. view it as a VM. you have to locate the bytecode that is responsible for the craft_req_check function.
i remember doing similar stuff with ps2 emulator + GOW2 in the good old days.
