Deco Cassette startup error in 0.228

Updated my 0.227 mame collection to 0.228 because the current atarisy1.zip gives a checksum error in 0.227 and only works in 0.228. Unfortunately, while that problem is gone in 0.228, it shifted the problem to Deco Cassette titles. With the same roms and deco bios, 0.227 started up the counter until the game was loaded and ran fine. In 0.228, every title I checked so far gives a cassette error warning and an annoying sound and stalls. Is this a bug in 0.228? Is there a way around it?

Nvm, figured it out myself. The default regional settings of the DECO bios seem to have been messed up by the migration from 0.227 to 0.228. All there was to do is save the correct Bios type (Japan or USA) for the respective version of the rom file in the MAME machine settings and the counter starts regularly until the game starts.
