Say “hello” to the Crystal Castles Prototype Serial #0067 by Atarisoft for the Commodore 64:
In doing some research, there were apparently only two prototypes of Crystal Castles known to have surfaced since the 1980s:
- #0008 (in a private UK collection since 2002)
- #0053 (recently sold on eBay January 23, 2016 for $404.00 USD)
And now #0067 as seen here on the Commodore Computer Club website.
Something interesting to note, Atarisoft only published the following 12 official Commodore 64 cartridges between 1983 and 1984:
- Dig Dug
- Donkey Kong
- Jungle Hunt
- Moon Patrol
- Ms. Pac-Man
- Pole Position
- Robotron: 2084
Notice that Crystal Castles never had a official release on cartridge for the Commodore 64, just the small handful of prototypes that have surfaced.
According to Wikipedia Crystal Castles for the Commodore 64:
Simpler graphics, but the gameplay is quite close to the original. There are actually two versions: one by Atarisoft that wasn’t released at the time but purchased by US Gold and released in Europe in 1986; and one by Thundervision in the US in 1985.
So there you go, two versions for the C64: one by Atarisoft that wasn’t released (this prototype version) and the US Gold (Europe) / Thundervision (USA) version.
Fun fact: Crystal Castles was only officially released for the C64 on floppy disk and cassette tape.
