Syzygy Okay so. And I am learning all of this to. Just like you could add the Atari 2600 expansion to the Colecovision, or the Adam expansion. In 2012 courtesy of this article a new add on was developed for the front of the Colecovision to bring it closer in spec with the MSX 1.
""The idea for the Super Game Module and the new cartridge PCB was to make more complexed games for our ColecoVision. The Opcode Super Game Module upgrades our current ColecoVision video game console from its standard 1 K RAM, with up to extra 32K (24) RAM.
Both SGM1 versions of the Super Game Module has also a more avanced sound chip inside than the one in our ColecoVision. This avanced sound chip was one of the most known out there in the 80’s, namely the AY-3-8910A.
AY-3-8910A was already a known audio chip, for example in some MSX computers and earlier arcade machines."
This allowed for a bunch of MSX conversions (I got started on all this trying to find a good way to play MSX Goonies) but also the added RAM allowed for much more complicated homebrew. So basically under the radar there has been almost the equivalent of Atomiswave games on Dreamcast, but for much weaker hardware all due to the Colecovision having an expansion slot.
