Yeah good point, the FBA emulators also run recent MAME romsets, those are worth a try too.

You can also run the very latest lr-mame on RetroPie.

However, even the latest MAME doesn't have the 2D games right. If you truly want to play these games, fix their emulation in mainline MAME then consider backporting them to earlier stable MAME libretro cores.

@pjft It's more a pain I can't roll back easy. I going to have to do a fresh 4.3 install. But I agree, shit ain't broke so should have stayed with it :)

I will continue there if I have an update.
