Download from Hardware = Bad Bin?

[TunerTom]

I'm using an Ostrich 2.0 emulator with Tuner Pro RT. After I make all the map adjustments I want, I went to Tools>Emulation>Download Bin from Hardware, thinking that would give me the BIN currently in the Ostrich (so I could burn a chip). However, I'm getting a BIN with incorrect (random) values. Is there some trick to getting the BIN off the Ostrich? TIA

Never mind, I figured it out. The BIN size was wrong in the XDF header. Getting to the point where you can't rely on free downloads from anonymous sources anymore.
