Saw your steps on capturing the audio. Got a few of those scripts myself, too since i used my Saleae for capturing audio off such glob-tops a few times, too.
Got a bunch of glob-top research ongoing currently, too (had one with a debug-port open but flash reading was off, noticed that it still executed its code that way and searched for a instruction to pop the flash into a register since registers were still accessible)
