No.17667 Andrew Tester May 22, 2020, 16:48	The corruption is still there at the title screen and randomly at the game level select in 0.221. I narrowed down when it first appeared: 0.142. The whatsnew for that cycle indicates some cleanup done on the driver. https://www.mamedev.org/updates/whatsnew_0141u1.txt -Placed full megadrive code in MAME section [David Haywood] -Reorganized megadrive/sms sourcefiles for better sharing between MAME/MESS.
