Not very amazing but I have a Famicom, a Famicom Disk System, Doki Doki Panic (Rarely works though), Super Mario Bros., Super Mario Bros. The Lost Levels/2, Return of Mario and something I can't prononce Mario on a Famicom Disk, Super Mario Bros. 3, Super Mario Bros. 2/USA, Fire Emblem and Fire Emblem Gaiden.
I have an English to Japanese game converter for the SNES and I own Fire Emblem Monshou no Nazo (Mystery of the Emblem), Fire Emblem Seisen no Keifu (Genealogy of the Holy War), and Fire Emblem Thracia 776.
I can play the games without understanding Japanese for some of them but others I can't play because I have no idea how to speak Japanese.
