I did load the DEH file and I still got the wrong texture issue if loading the mod from the standalone "Doom II" tab and not the "Doom I & II" tab with the original DOOM2.WAD file and not the one used by BFG Edition. I even swapped the load order of the Batman Doom mod (BATMAN.WAD 1st, BATMAN.DEH 2nd; BATMAN.DEH 1st, BATMAN.WAD 2nd) and I still get the wrong texture issue. If I didn't load the .DEH, the side effect I would see is the enemies and some of the sprites being mismatched instead of the Doom 2 textures cropping up on buildings. Loading the Batman Doom in the "Doom I & II" tab was the only way it works properly from my experience.

@AmethystViper For barman doom mod make sure you also load the .den and you are using the original version which was running on vanilla doom, for the sc-55 I think the issue is that the files are not midi to begin with. As for the stutters well dunno.
AmethystViper Mar 14 @ 9:36pm 
I also kinda noticed some slight stutters sometimes in the latest revision of v1.8.1.2., though I'm not sure if it's just my PC or something with my settings though I turned down most of the visual settings (e.g. soft shadows since it's really taxing on my PC, HDR, SSAO, the forced ambient lighting). I'm not if it was also the cause in the previous versions of Classic RBDoom3BFG.

The performance issue is fixed in this latest revision, however I did ran into an new issue with Batman Doom when loading the mod through the "Doom II" tab and not the "Doom I & II" tab where the original textures from the mod don't work and the ones from Doom take over:

SC-55 mods do work now but the playback isn't seemless like the default MIDI though this was also an issue I've also noticed when using them in classic Doom source ports like G/ZDoom.

@AmethystViper I also forgot to mention that version deal with the issues you encounter with batman doom and doom sc-55 mods

@AmethystViper @27lueddi87 revision 2 of Classic RBDOOM 3 BFG Edition version has just Released. (hopefully) Fixed the performace issue.

I also ran into an issue where using this mod that is ment to fix leftover visual errors on the classic games' sprites and visuals but upon trying to load the games using the mod it refuses to play.
AmethystViper Mar 14 @ 12:53pm 
I did a clean re-install of RBDoom3BFG v1.8.1.1 (from a clean re-install of Doom 3: BFG Edition from GOG Galaxy, and I can't use v1.8.1.2 due to the current performance issues) and I was able to get the mod to work but only through using the "Doom I & II tab" from the launcher; when I was using the standalone "Doom II" tab to load Batman Doom was what crashed the game but I don't get why this was the only the mod works seeing that Batman Doom is a Doom II mod and not a Doom I mod since it feels kinda misleading when loading mods made for specific classic Doom games. RBDoom3BFG also crashed when starting Doom I due to how Batman Doom needed to be loaded in order for it work without crashing as mentioned earlier.
MaDShadoW  [author] Mar 14 @ 9:55am 
@AmethystViper Try to do a clean install of classic RBDOOM3BFG delete any file that is asosiate to this mod/sourceport (including the 3 wads) and install it again. Batman Doom as far as I know works perfectly well in the latest versions of Classic RBDOOM3BFG but if it crashed try to reload it. Who knows maybe it's a one time bug.

A follow-up crash report: I tried using the Batman Doom in Classic RBDoom3BFG for Doom II, and at first looked like it was going to work but then when I went into New Game → Hell on Earth, the game crashed.I was using the CDL Launcher to load the Batman.WAD and Batman.DEH files to try and get Batman Doom working.
