Playstation DOOM TC is a mod for DOOM to the engine GZDOOM, based in the original PSX DOOM exactly mapped with the same graphix and colormaps. this is beta 3. do not use other engine or skulltag only GZDOOM.
I think at the time, we weren't adding new mods and it wasn't in complete form but I'm glad to see Beta 3 was released just a few months ago so I will add it to site tonight.
