Decent hack, but it crashes on some levels after you die on real Super Famicom (NTSC-J) and then press any of the action buttons to enter the level after the Nokia 3310 ringtone and getting kicked back to world map.
Could be custom music issue, because it seems to hang just before the level has loaded. Also seems just Mellow Meadows 2 (can't remember the name) is affected. Other levels are fine (only played to first castle).
I love the Rosalina and Peach NPCs. They'll follow Daisy around and mimic her movement. Reminds me of Sonic The Hedgehog 2 and Tails' AI. Haven't been able to kill them by accident... yet.
