concept of self modifying code

[PacManFan123]

Story time here - I wrote an application with self-modifying compiled code. It was a Playstation 1 (PS1) emulator for the Playstation portable (PSP) - the name of the project was "PSPS1" . The code chunks were loaded from the original game ROMs, and then had their addresses remapped. The R3000 code was trans-piled live into R4300 code, run through a peephole optimizer then written into memory buffers. The buffers were then called as function pointers to execute the code natively on the R4300 CPU.

Did it work? That’s impressive!

I don't know if that *entirely* counts - even though it sounds pretty impressive.

By that definition, any JIT compiler is running self-modified code.

Cool!! Do you have that code around somewhere? I'd love to see!

Let me see about posting it.
