Hardly. Even you must admit baseline MAMEUI has been on life support for years. Even with the best efforts of some pretty damn good coders, there's only so much you can do with a crumbling foundation.
MAMETesters does not accept bug reports from baseline MAMEUI, much less the more borderline hacks you've been known to use in the past on MAMEUIFX. That by itself implies a certain wariness about MAMEUI's UI creating some potential issues with the emulation quality compared to MAME itself-- which has been demonstrated clearly through the years by bug reports that are directly related to MAMEUI or derivative builds.
Therefore, MAMEUI can be called buggy.
There's no offense inherent to that, either. I think even the guys who've kept MAMEUI shambling along at this point are willing to admit that-- like I said-- there's only so much that can be done with an old codebase with old assumptions.
