Need help ripping models from No More Heroes 1 & 2

[punchbee]

Hello everyone, I've been doing a lot of research for these files with no such luck for finding a model extractor for the .GM2, The header contains "GMF2" which is a Grasshopper Manufacture model format, From what I did find from the .GM2 is GCT0 which is a image file which I can use Dolphin Texture Extractor for. Any help will be gladly appreciated!
