Perhaps a little spammy post, but I can't resist it: Oh man, I have to re-thank you for the Dosbox! Without it, I couldn't play one of the greatest games ever made, the game I'm currently playing: Panzer General. So: Thank. You. Qbix.
Btw, for some reason now my computer can handle dosbox so well, that the sounds play perfectly in PG. Even better.
