>Is the current version in MAME the same as the one included in Sega Ages 2500 Vol. 23?
I never tried playing the emulated game in MAME before [currently using an old-out-of-date Sony Vaio system from 2003 that can run versions of MAME up to .178...nothing newer than that]. I wouldn't know if it is different than the product [Sega Ages 2500 Vol. 23].
