ZDoom

There are no facilities to use Sigil as a pseudo-IWAD so of course there's no renaming going on.

This brings up another question, Graf: In the case of SI6IL, does ZDoom do any renaming of lumps to avoid conflicts? I was trying to make a separate wad that if it detects SI6IL, it will load the upscaled title/inter/END pics... but I think ZDoom just looks to see if there are new gfx, and overwrites the original Doom title/etc gfx. Is this true? To make them high resolution would you need to include them inside the sigil.wad?

You have to name them NWILVxx. GZDoom renames those graphics upon load to resolve the conflict.

I was trying to implement higher resolution mapname gfx for starting/ending a level, but nerve.wad uses the same entry names as Doom2 so I can't simply put a high res version into a FILTER folder and expect it to upscale. Would there need to be another folder called DOOM.NERVE where I could put the images so they don't overwrite the original Doom2 mapname images?

This got added.

In the interest of not being a boorish asshole and forcing this change, I simply PR'd it for approval. I've tested it - and it works (did I really expect it not to?), but with and without nerve.wad present. If it's there it simply loads it, no biggie.

You can just autoload nerve.wad with Doom 2 and it recognizes the addon automatically and renames the mapnames so they work with GZDoom's internal episode definition anyway.

Huh, I didn't even know there was first-class support for nerve.wad. O_O

I'm kinda torn about this -- on one hand, it's a cool feature and it's kind of a shame that it requires using the bootleg-quality BFG Edition IWAD in order for it to work, but on the other hand, it's technically accurate to the release versions of both games. Damned if you do/don't/etc, I guess.

The default IWAD definitions only autoload companion WADs that were required by the official releases (ie. voices.wad for all Strife versions). Anything beyond that is frankly a matter of the user's taste, and best left up to them.

Currently, only Doom 2 BFG edition automatically recognizes "nerve.wad" as a separate episode. To use it with the original commercial edition, you have to manually add it in .ini and it works without problems. Took me a while to figure out why it didn't recognize this episode only to realize I needed BFG edition.
