A "perfect" MAME collection is a lie. The truth is the mess. The truth is the bad dump that crashes on level 3. The truth is the Japanese mahjong game no one will ever play. MAME stands for "Multiple Arcade Machine Emulator." But the developers renamed the project to just "MAME" years ago. The acronym is dead.
