I haven't launched from the menu so I can't confirm the sound quality is any worse. From the command line with sound quality at the default low it's fine. I turned graphic detail to low and tried it at 640x480 but it was kind of laggy. 320x200 reduces things to the size of a postage stamp, but it's fast... providing you don't care being able to tell which way your ship is facing in combat.

As a work in progress, Super Melee seems doable however when I try to visit a planet it crashes; when the UrQuan drone comes to warn me about approaching Earth, the UrQuan just sits there twitching - - no speech/text.

The RPG isn't playable at all, Super Melee should be providing you can configure it properly. Hats off to this ambitious attempt, best game of all time.
