Yes, actually work on that has really heated up lately. All the carts except Space Destroyers have been dumped, and are believed to be good, with two revisions for Catena. Space Destroyers should be dumped eventually. There also appear to be two revisions for the BIOS, though we're still working on confirming that. PeT has made a few updates to the MESS driver. It isn't fully working, but some games are playable. Some Imagination Machine software has also been archived, but isn't playable in emulation.
