If a game specified multiple names for an IWAD, the resource locator would find one of them and only then check if it contained the required lumps. However, some games may use the same file name with different lump conditions (full Hexen vs. Hexen demo). In this case, the locator failed to find the demo IWAD because it only checked the file it found first -- the full IWAD.
The game resource validator was modified to check each alternative name separately. The first one to fulfill all conditions is selected for use.
Todo for later: A more elegant solution would be to move the resource validation logic into AbstractResource.
