This is my foray into dynamic recompilation using PicoDrive, a
Megadrive / Genesis / Sega CD / Mega CD / 32X / SMS emulator.
I added support for MIPS (mips32r1), ARM64 (aarch64) and RISC-V (RV64IM) to the
SH2 recompiler, as well as spent much effort to optimize the DRC-generated code.
I also optimized SH2 memory access inside the emulator, and did some work on
M68K/SH2 CPU synchronization to fix some problems and speed up the emulator.
I added support for MIPS (mips32r2), ARM64 (armv8), RISC-V (RV64IM) and
PowerPC (G4/2.03) support to the SH2 recompiler, as well as spent much effort to
optimize the DRC-generated code. I also optimized SH2 memory access inside the
emulator, and did some work on M68K/SH2 CPU synchronization to fix some problems
and speed up the emulator.
It got a bit out of hand. I ended up doing fixes and optimizations all over the
place, mainly for 32X and CD, 32X graphics handling, and probably some more,
see the commit history. As a result, 32X emulation speed has improved a lot.

lot of bugs were fixed, and some new features (e.g. chd file support) have been
added.
