I think I'm actually gonna try this. A 6x6 board should make 4 blanks, and it's < $10. I can go single-sided (Yeah, I already did the layout) for the test boards. Another $20 will get parts for all 4 boards, so all I need now is an eeprom programmer :-)
And the light-cycle game is just for testing - it's small, already written, and should work from eeprom. IF we decide to do it on a larger scale (ie, more than 4 boards), We'd need to go with double-sided pro made boards (there's 50+ through holes for the us/jap version!) . At that point, yeah, we'd have to write a game for it to make it worth while.
