While getting that Sega Channel related device dumped, I also got another oddball cartridge dumped. The cart is plain and only has a "Universal Driver Test Program" label on the front. It will run in emulators and on an Everdrive. The only screen moves a cursor with the d-pad while changing values on screen and also changes values when a button is pressed. As far as we could tell, it was used to demonstrate and test controllers and peripherals. The code even mentions the Activator and the Mega Mouse. http://s000.tinyupload.com/?file_id=94446150587518812349 There is another version of this ROM out there (Version 4.0), but given the earlier date and lack of version number on this one...it could possible be V1.0. If anyone has a concrete idea as to what this was for, I'd love to know. Otherwise, feel free to mess around with it!
