The IDgames archive at Doomworld It is, to my knowledge, about the biggest archive of Doom, Doom II, Heretic, Hexen, and Strife (And HacX too) Wads to be found anywhere. Basically, just take a look, find ones you like, and make sure they fit whatever specs that Doom on the GP32 has (For example, IIRC I read someone point out that it can't handle DeHacked patches, so avoid WADs that need it)
