Don't know if you knew about this either:

Get the files, get the remixed music, manually map your joystick buttons in the config file. (It puts the config file in your Documents and Settings folder under Application Data. (The one in the game folder doesn't work.))
I just got a savegame editor too. (Going to use it to get a little more cash, so I can go exploring a bit.)
SpiderMonxey and I just started a game, and it's quite fun. It's the 3DO version of the game, but you can customize it with things from the PC version, (like text instead of speech) and things like that. I suggest you set it all up nicely, with scanlines, joystick, remixed music, and you'll have a nice fun long game to play. Oh, and Super Melee is really cool too. I have the Joymaster set up for dual play. I've been to busy to create a Melee fleet though. Once I do that, it will be a lot more fun.
