I’ve been decompiling a PS1 era game for the past year or so, and it was so nice to find Sony used GCC as their compiler. There’s a significant number of MIPS tools in GCC that still work, the source and patches from that version still exist, and are open source. PS2 seems similar, but for the PSP they chose MetroWorks instead, which introduces some challenges, primarily just knowing quirks about the compiler. I wouldn’t be surprised if most languages supported by GCC (and possibly clang as a front end) could target many older systems as long as the runtime can be statically compiled into the final binary.
