Did you buy the collectors edition or digital edition without the cartridge?

The software on the cartridge is used to load the game faster on an actual TI-99/4a.

Current Version information: http://quixotic.adamantyr.com/roa-version.htm if there are updates to the software you need to update your cartridge rom. I sell updated roms and or a service to send in and have your existing cart upgraded. See related items

NOTE: you can not use this cartridge by itself, it requires the entire package either digital or collectors edition to play the game.
