Only act on messages about textures being the wrong size, and parsing errors in the config.txt file. In TRS06 the content creator program can fix a lot of the parsing errors, but the texture sizes must be fixed with PhotoShop, Paint Shop Pro, Gimp or similar program. Texture images must be a power of 2 in size... eg 32x32, or 32x64, 128x128, 256x256, 256x512, etc. and the alpha image must be the same size as the texture image, if they are separate.
