...is set to go in future .226 release [for those that don't roll their own builds] for the Sega Mega Play fans. Good detective work.
- fix a Genesis VDP status bit which was breaking Mega Play 68k->Z80 comms #7390 Oct 24, 2020

This entry is on the way out.
-- megaplay
Interaction between BIOS and 68k side is not fully understood. The BIOS often doesn't register that a game has been started and leaves the 'PRESS P1 OR P2 START' message onscreen during gameplay as a result. If this happens, the games usually then crash when you run out of lives as they end up in an unknown state. -
I wonder what it will require to get this other entry resolved.

Incorrect behavior at time out and there are some sms based games which aren't yet fully supported. -
