This was one of the first releases by Australian software giant OziSoft, who went on to release the Sega Genesis and was eventually bought and renamed Atari Australia. It is now owned by Namco Bandai.
Both a cassette and disk versions were released. Sadly, no cartridge version was ever made for the C64.
The manual mentions (Australian) Amstrad versions, which we are missing! If you have it and wish to donate it to the Miner 2049er Museum, please reply to this post! We’ll even accept just a picture if you don’t wish to part with yours.
