Minna no Taabou no Nakayoshi Daisakusen - Reset Fix by TakuikaNinja This game enables NMIs in the reset handler while waiting for the PPU, causing the NMI handler to kick in before RAM is initialised. The NMI handler expects $10 & $11 to contain values > 0 (possibly some kind of NMI ready flag?) and will hang the game if the emulator initialises it with $00. The fix is to disable NMIs before the PPU wait delay loops and re-enable them afterwards (the game already does the latter).
