Generally main r5900 recompiler subruntime is located at 0x174188 | Generally main r5900 recompiler subruntime is located at 0x174188. This is the place where r5900 (MIPS/COP0/COP1(FPU)/COP2(VU0-macromode)) opcodes are directed to emitter and analyzed. Jump table as is. Many opcodes jump out to different runtime due to complicated EE nature. | ||

Direct function | [sarcasm mode ON] Due to totally lovely, and 100% sane Emotion Engine architecture [sarcasm mode OFF] VU0 recompiler run on PPC because running VU0 on SPU is not able to give needed timings/sync with EE mips core. Direct function addresess here. Few "accurate"/"inaccurate" functions are missing on that list, bur you really can see pattern on other ones if needed. | ||

After resolving above functions, you can see some sub_ in recompiler runtimes. This are usually used to translate ppc/spu reg to mips/c0/c1/c2/vu0/vu1 regs. Easy to cache due to extrdi which indicate field/reg bytes. | After resolving above functions, you can see some sub_ in recompiler runtimes.
