I guess I could ask here and save time... what's the state of game.com? does it work? or is there a bunch of bugs or something? I have the data sheet for the CPU in it and fully reverse engineered the hardware (i.e. pinned out the cartridge socket, the system, all connectors).
I know there was an emulator written back in the day for game development, but again not sure how complete that was. It was certainly complete enough to run the games for development I guess.
Having a baseline will help me know what parts to concentrate on.
