In an amazing technical achievement, Vince/Deater has done a ‘demake’ that brings Myst on the Atari 2600. Originally it was done using Harmony Cartridges that have 70MHz 32-bit ARM microcontrollers on them handling the bank-switching and other signaling. But could you get it to work on actual vintage 1980s cartridge hardware?

It is playable, but likely not really understandable if you hadn’t already played the original or knew what certain things were. Then again, it might not be the most confusing game for the 2600.

In the end, deater.net was able to use a M-Networks “E7” chip using the full 16k of ROM and 2k of RAM capacity, but it turns out possibly no one had ever used all 2k of RAM before.

This is very impressive considering the original Myst barely fit on a CD-ROM with 650mb of storage:
