I speak no spanish, but I figured the author is reading here, so I'll try it in english:
there seems to be some issue, I am not sure what exactly. When I create a .wad using win XP on this PC, the resulting file is bad, it will not install (-1022 at the first content file). Several others have the same issue. The .wad file is 13.377.599 bytes in this case.
Now the strange part: if I create the .wad on the same PC, but in vmware running vista, the resulting .wad is 13.325.568 bytes.. and works perfectly fine.
I don't think it's related to XP and Vista directly, but some bug in wadpacker, maybe with certain programs on the PC or something.
I apologize for posting in the tutorial thread at first, it was a misclick.
