Play Sufami Turbo Add-On Base Cassette (Japan) Online
This weird little SNES adapter lets you slot in tiny game cassettes—mostly chopped-up Gundam episodes and a few oddball ninja/Ultraman titles, like Bandai’s strange love letter to physical media.

Game Overview
Okay, so the Sufami Turbo was this weird little add-on for the SNES in Japan—basically a cartridge slot that let you plug in these tiny game cassettes. This ROM is the base you need to actually play any of the 13 supported games, which is kinda funny because half of them are just SD Gundam titles split into six parts (why?!).
You’ve got some oddball picks in here too, like Poi Poi Ninja and Ultraman stuff. The whole thing feels like a novelty—like someone at Bandai really wanted SNES owners to experience the joy of swapping tiny cartridges. It’s neat for collectors, but good luck tracking down all the actual game cassettes now.
Honestly, the most interesting thing about it is how bizarrely specific the library is.
