Theoretically speaking, would it be possible for a version of TSLRCM + M4-78 to be ported to the Xbox version of TSL? I'm curious since I've seen alpha maps of M4-78 and the HK factory work on it.
Well, if an xbox version of TSLRCM and M4-78 was made, then yes. The big problem has always been that the MDL format is different on xbox, so it was impossible to get any models to work. This will be possible in the future though, so theoretically speaking, yes
I just looked up some of the restrictions, which include the inability of using custom mdl/mxl files, textures higher than 256x256 and usually any MOD files. What do you mean it'll be possible in the future?
