I've made an editor for these texture files. You can find this on Github https://github.com/tofuman0/MIA-Manager
The textures used in SBOL use an .MIA extension. I'm unable to find any details on this format or if it is used in any other games. The format is unprotected and stored using a basic run length compression for the pixel data.
