Over at DCEmu, masonman shared his LUA game pack.
All you have to do is extract it to your apps folder, and, according to him, you may replace your lowser folder with his mowser folder if desired.
South Park Wars is included in the package. The game's goal is to jump over your opponent to cause damage to his health pack, until eventually, he dies. And then you win. The shoulder buttons are for the jump action.
Anyway, here's what you'll find in the package:
* BHB 3.0

o analog test
o highscore share, and more
* Word processor
