I mean backwards incompatible changes are not accepted. You said 'it's stable', meaning it's not crashing i guess ? dozens of fixes, literally, just look at the neogeo changelog between mame 0.78 and now, there are more than an hundred lines and most of them are fixesĪnd with FBNeo, you can even use retroachievements. Now some real reasons to use a more recent emulator : Is downloading the newer version of a few romsets every 10 years such a big deal ? Neogeo games aren't something that has been constantly redumped over the years, and there is always a very good reason for redumoing something, most of the time that means the older dump was corrupt and prevented the game to actually work as it should. you said 'the romset is stable', which means 'the romsets aren't changing' i guess, the lazyness argument, fine, but actually most neogeo dumps from mame2003-plus are still usable with more recent emulators. you said 'it's stable', meaning it's not crashing i guess ? well, it's not as if neogeo emulation was something very unstable in other emulators either, so how is that even an argument ?
