What's New:
With MAME 0.274, an ARM64 dynamic recompiler is introduced - a much anticipated and very welcome development. This immediately renders these Intel64 builds for ARM64/Silicon Macs irrelevant, as now the 'native' Silicon build runs faster on all games.
I nevertheless provide this Build 0.274, as it also decently refreshed the Intel64 recompiler according to the release notes.
