That's great!, thanks. Are you using an emulator or a real DC?, I'll gladly burn and test it on the real hardware for you if you need some feedback.
While testing out Law56ker's collection a few months back with Freedoom, I noticed that Hacx wasn't working, so I replaced the Hacx WAD. It seemed to run just fine, but I didn't go through the game looking for everything mind you...
Only thing different with the image I just linked to is that I added the Sam Woodman help demos, which were popular back in the day.
When I made my last post, I had thought that Law56ker had already found a working WAD, so I'm sorry if I confused anyone.
Here's a possibility:
If I'm correct that it works with the latest Freedoom free-of-bugs, all you have to do is merge the Hacx wad into the Freedoom wad. just include the Freedoom redistributable text with your collection.
Actually while your at it Law56ker, you could just include the Freedoom wad (renamed to avoid auto detection) separately, and not merge it. It then could be used for some of the other wads on the disc like Hacx, Batman Doom, Aliens TC (looks better than with Doom II), etc...
All you have to do is eliminate some of the excess like say... the Memento Mori music wad (mmmus.wad), and the Requiem music wad (reqmus.wad) which weren't being used anyways.
