As most of you know about the SXTBFM, it botts the bogus 1.0 firmware. I thought this firmware was VERY impressive (visually and audioly). So I tried to remove the sound form opening_plugin.rco and patch it to my 1.5 firmware. But, once all was extracted and patched, I went to emulate my 1.5 firmware and all it did was this screetching awful noise. Can someone help me?
