EmceeMart nearly always includes TXX and TXP files with his tracks, including the latest, so people can use his textures and stuff. TXPs are Traxx patterns (pre arranged textures). Heck, his latest track Ramparoony only uses a small part of the textures he made for it, the rest are off in the corner feeling rejected.
Also consider all textures made by
OOPS, I believe he allows use of all textures he's made for all of his tracks (Evo1 and 2 use the same format as MTM2), and some are even packaged seperately.
Everyone mentioned so far encourages the use of their textures.
