Every once and a while we’ll see some sort of Altoid container mod: one that has a built-in MP3 player, one that controls the weather, one that alerts you to approaching nerds, etc. This mod, created by one Greg Sanders, houses the video game Dungeons of Doom, an off-shoot of the classic Rogue. (Not that I’ve played it, but that I recognize its classicness, to invent a word.)
A Sega Genesis controller controls the game and its schematics are readily available for your enjoyment.
Wow, this is a nice peace of work. Great job!
