Emulator have some leftovers from PSP emulator (like axinsnreplace), so core of non PS1 specific functions is the same as in PSP emu. Rest of emu seems to be "inspired" by mednafen. | Emulator have some leftovers from PSP emulator (like axinsnreplace), so core of non PS1 specific functions is the same as in PSP emu.

Example: Medievil internal emulator, standalone pkg can differ. | |||

Lua patches are split between 3 categories R3K (r3000 mips), and EM (emulator), TR (trophies). Called by getXXXObject. Only exception from that is apiRequest. | |||

Different emu versions support different highest api. Medievil emu support api up to 1.0 | |||
Calling api is mandatory. | |||
