Sorry for the confusion. While I am not new to the retrogaming community (been homebrewing for 12+ years now) I am relatively new to the VCS homebrew scene so please any mistakes that I may make. I've only published five VCS games so far. The game in discussion (Escape It!) uses bank-switching AND an extra memory chip, the Sara chip a/k/a the "super chip." These custom Atari chips are not something you can just buy from some old warehouse. They don't exist anywhere, so we had to take apart a Dig Dug or Crystal Castles, etc. There are only a handful of Sara based games and only these two are "common" that can be used to manufacture a new title.
Thanks for your kindness with the "semantics" comment, Stargunner :-)
