Perhaps my last, and most useful request:
As SASRB2's Demo has taught us, invalid/unupdated texture lists are a pain in the butt. So, why not have something in the MAINCFG to fix that? Instead of copying, pasting, and editing SRB2's textures1/pnames lists, why not modify it via a SOC? There could be a texture section for it...
TEXCFG
GFZROCK_H = 256
GFZROCK_W = 256
This would set GFZROCK's size in textures1 to 256x256, and leave everything else alone. No muss, no fuss. No "OMG CAN'T FIND THIS TEXTURE, YOUR TEXTURES LIST IS OUT OF DATE".
How's that sound?
