I forgot to say when I play "The Legacy of the Wizard" or "Dragon Slayer 4" when you fight the last boss of the game, It bugs out and it kills you like right away. I've tested the game with NesterJ emulator and that piece of the game worked normally. Heres the passwords I have for it, both of them has all items collected but one of them doesn't has the bosses defeated yet(I did this so I can fight the bosses whenever I want without having to recollect everything else again).

Sorry for the long post but I could never kill the dragon due to emulation error as I had always had to change to a different emulator to beat it.
