yeah i like rcotool as well but havent used it since the old days of making the rcoupdate batch files...but using rcoedit 1.14 and 1.15 and hex edit the wave would never display after injecting the z33 model.  :(  i even tried wave system 1 and 2 wiht no luck, only the waves do nuts model worked which was 26kb where as the ps3 style models were in the 140kb range :(  I'll try again using rcotool.  ;)
