Now the production of the XM units has moved forward and developers are starting to get test units, we'll be seeing new titles being made for the 7800 that take advantage of the XM's capabilities.  One of those titles currently being developed is Pac-Man Collection XM, which takes advantage of the 320 mode of the 7800. 

The video shows a WIP for Pac-Man Collection XM for the 7800.  It will require the XM add-on for Yamaha sound (done be Perry Thuente) and High Score Saving.  It will work without it, but you will get standard TIA sound and no High Score retention.  The game is about 75% complete with a few bugs and missing features (such as an actual random maze generator) and some missing TIA sounds (Yamaha sounds have not been started yet).
