Not talking about SF2. Talking about using the same .lod, but with different .bmps and .inis to call out the tank, without having to mess with the hex editor. For example:
Files in the white F-4 370 gal tank folder under the Weapons folder, which would be named "Tank370_F4":
Tank370_F4.ini
Tank370_F4.lod
Tank370_F4-001.lod
Tank370_F4-002.lod
Tank370_F4.bmp <--- Which would be white.
Files in the SEA camo tanks, which would be called "Tank370SEA":
Tank370SEA.ini
Tank370_F4.lod
Tank370_F4-001.lod
Tank370_F4-002.lod
Tank370_F4.bmp <--- Which would be in two-tone.
Contents of both the main .inis are the same, the only differences are the .bmp and the names of the folder and the main .ini itself. Though this would work only in versions of the games with the latest updates, and up to you to define the TankType variable called out for in the weapondata.dat file.
