It's a new blog about the Electronic Handheld Games in MESS (err...MAME!) that i would make simulators about games that have no micro processors (aka 4-bit CPU's) like those Electro-Mechanical handheld games (example: Marx TV Tennis) and also put information, scans and artworks for upcoming or already emulated games.
Go take a peak! =)
If these artworks are accurate to the handhelds (?) then I'll happily add them to the MESS Artwork page
