I'm also only getting 'Wrong UCode' and 'Fatal Graphics Emulation error/exception' (forgot the last one). Your non-texture-dumping plugin works OK, but this one not.. I did create several subfolders named 'Tiles' in the Plugin dirs of Pj64 and 1964.
And I'm also a sort of person who is REALLY desperate tou get his hands on N64 textures. I've tried the following games; SM64, DiddyKongRacing, Zelda, MK64 and some more. I don't know if anyone has succesfully dumped textures so far, if so please say how you did it.
And Icepir8, I really appreciate your work, I'm not flaming you, I just want the plugin to do what you say it can do.
