In the mid-1990s, Nintendo released Satellaview, a satellite modem for Nintendo's Super Famicom (SNES) only available in Japan. Just for kicks, Bertrand Fan hacked an SNES and Satellaview to run Slack. Bertrand has an intimate knowledge of Slack because he's one of the engineers building that platform. From Bert:
If you can beam satellite signals to a SNES, you can probably run Slack on it…
Most SNES games are closed systems. When you play a game like Bronkie the Bronchiasaurus, an educational game about dinosaurs with asthma that teaches you how to use an inhaler, the content is fixed on the cartridge.
But the game that comes with the Satellaview, BS-X: The Story of The Town Whose Name Was Stolen (BS-X それは名前を盗まれた街の物語), is different. It looks like a lot of Japanese RPGs but has one key difference: it can receive content beamed from the sky and that content gets integrated into the game….
Using a tool called SatellaWave, you can generate your own Satellaview Broadcast binary files.
