I was wondering if it's at all possible to replace models in gamecube games, especially if the replacement model comes from the game itself. For example, in Luigi's Mansion there exists a model of mario stretched to have Luigi's Proportions http://tcrf.net/Luigi's_Mansion#Unused_3D_Models I was able to swap this model with toad's by unpacking the ISO switching the names, and then rebuilding it with GCRebuilder. Warning: Spoilers inside! However, if I tried switching the Mario and Lugi model file names, there didn't seem to be any difference. Does anyone know why that is or how to get around that?
