Static recompilation of CHIP-8 programs

Static Recompilation” is the process of turning a binary program built for one instruction set and CPU into equivalent native code for a different architecture. It’s a hot topic lately as news of a static recompilation process for N64 games – turning the original MIPS code into x86 executables for Windows – seemingly promises an entirely new level of features and performance beyond existing emulation techniques.

Greg Kennedy looks into it:

I’ve been interested in the topic since hearing of the StarCraft on ARM recompilation for OpenPandora in 2014, but not looked too much further into the idea until recently. I decided to try my own hand at a static recompiler, where I would be transforming some machine ROM into C source code, then compile that to produce native executables.
