Thanks to Rene Balke, Darksoft and Arcadeautomaten/Senil Data Systems the rare Data East Cassette game Nebula was dumped. This is a UK region cassette and is the 6th game that was released on the DECO Cassette System. I did some work on working out how the encryption applied to the tape here, allowing it to boot in MAME. It's a traditional Galaxian style game that is clearly reusing code from the earlier Highway Chase. I feature Highway Chase footage at the end of the video.
