I wanted to try some GRP editing, combining units and such, because it looks so cool. I downloaded WinMPQ and RetroGRP. I used WinMPQ to open up Stardat.mpq, and there were a whole load of files named unknown and numbered. I figured I just wanted GRPs, so in the list section I put "*.grp", nothing came up. There were Broodwar units in Broodat.mpq, I got a valkyrie. But I also want regular units, like carriers, scouts, shuttles.
Wow... I owe you one.
Firefox screwed up your post, it didn't show the part after the link until I hit reply, then it showed it.
