Part of the reason MAME has gotten so large, so memory hungry, and so very slow is because it supports dozens of Japanese mahjong games, often featuring a cast of schoolgirls in brightly colored costumes that are ripped from their bodies as gameplay progresses. Does anyone bother to play these games, or even know how to play them? Are they really so important that they should remain an anchor around the neck of an already bloated emulator? And are they appropriate to include alongside more wholesome games, like, uh, Mortal Kombat? Wait, maybe that wasn't such a good example...
Anyway, please vote and add your thoughts here.
