There is a way to play Joust, Joust 2, etc... (although u may still not want to play them see results below) by using the reset game in the VI Menu screen. Assign one key for VI Menu and one key for VI Enter. When the game say "factory settings restored" hit the VI Menu key and select "game reset". Press the VI Enter key and wait for the game to start back up. The Title Screen will appear. However....

1. Joust - very playable but doesn't entirely fit screen.
2. Joust 2 - sllllooooowww reallllly slllllooow and I cant prevent a ghost player 2 from joining the game at start up.
3. Sinistar - very playable though difficult to control.
4. Defender - 3 buttons, fire, thrust, smartbomb only - GOOD LUCK!
5. Stargate - see above.
