neo-po.bin, neodebug.bin, neo-cpo.bin, uni-bios.20 = bios files google bioshouse
261-c1.bin, 261-c2.bin, 261-c3.bin, 261-c4.bin = rom files for the game you were trying to run.
i best suggest you use the dat that it comes with or makes in your xbox and use romcenter (pc app) and let it check you roms to see what is either wrong, missing, or misnamed.
i used romcenter it did help but as far as bioshouse i did google and bioshouse couldnot be found and im still having no luck finding the bios..
