We have added the TI-99/A4
to the site and are accepting game submissions for it. The next platforms I'll be working on to add are WonderSwan, WS Color and Neo Geo. If you want to see a platform added to the site sooner please send me an email
and I'll discuss the details as to what information I need in order to add the platform to the site. Also, if there are any tech attributes or rating systems missing for any particular platform please let me know.
