Cauterize of RetroCollect fame) the fascinating work of user guacasaurus_mex. I see what you did there with the name, Mr Mex. Very clever. But not as clever as the VMU-based creations on your Instagram page!
Behold - a Star Wars: The Force Awakens mini game for your trusty old VMU:
There's a whole raft of other creations hiding on guacasaurus_mex's profile page and while some of them are merely proof of concept demos, others are pretty much fully fledged games. There's no information on if or how these games and demos will be released for public consumption just yet (although a 25 game compilation for use with Dreamshell has been mentioned), but I'll be keeping an eye on developments. I'm already predicting a drought of CR2032 batteries across the globe as soon as these hit a download service.
Thanks to guacasaurus_mex for permission to post these images here (make sure you go and follow him if you're an Instagram user, and tell him where you saw his work!), and thanks to Cauterize from RetroCollect for the heads up on this brilliant project.
