Anticipating the days when Drum Mania series will be fully working, but that will be awhile.
Meanwhile OG and RB have done a couple updates with Keyboardmania getting Keyboardmania a lot closer to fully working status even though it is working at this time. Probably a few more specific src/mame/drivers/firebeat.cpp updates before official release happens.
More Mattel led games being supported, more updates and improvements to earlier generation of Mac computers, and Bemani updates, and some fruit machine updates....there shouldn't be an any unsatisfied .230 folks/users other than maybe the griping "r/emulation complaining kidz".
btw: I am certain the "r/emulation complaining kidz" are probably stuck in Conan O' Brien's Naughty Land at this time. As Conan says: "Kids. You do not want to go to Naughty Land."
