MAME 0.274 for Silicon Macs received a Dynamic Recompiler

Just a few days after my post on Intel64 builds, these thoughts became redundant because MAME 0.274 for Silicon Macs (along with other ARM64 platforms) received a dynamic recompiler. This finally brings MAME on modern Macs fully en par with Intel64 platforms and makes the Intel64 builds redundant for Silicon Macs.

That's a lot of benchmarks!

These benchmarks speak for themselves: The new dynarec lets my M2Pro Mac fly in games requiring a dynarec. Besides the listed games, probably all games requiring a CHD (Compressed Harddisk) will gain such dramatic performance improvements.

On the RetroArch side of things, the improvements are less dramatic. In games requiring a CHD, I still see games suffer, e.g. gauntleg. This will require further testing. But for complex games, MAME official is now a safe bet on modern Silicon Macs.
