I've still got the last levels of Mayhem, Present and Sunsoft to beat, (Thats, "Lemmings ark", "Final Impediment" and "Fall and no life (part 2)" ). Thats basically because I lost the passwords X_X. The Lemmings planet passwords wont work, and I think that's because my ROM is PAL. Those codes only work for NTSC ROMs, but if I search the net long enough, I should find them.
