I’ve finally obtained a copy of the ROM for the All Night Nippon version of Super Mario Bros.. If you’ve not heard of it, it’s a version of SMB made back in 1986 as a promotional game for the All Night Nippon radio show in Japan. The game was only released in Japan for the Famicom Disk System, and is quite a rare find.

Here’s part one of my five-part Let’s Play on this game, wherein I go all the way through, from stage 1-1 to 8-4, showing off all the differences from the original SMB to this version.
