I have make some several test of divide on my +2 and yes a big quantity of TRD doesn't work or bug like the demo Weed by exemple the demo start but on the midle the machine just freez...

And why would it not work with it) I can not check my emulator FDD not, but with floppy disk drives work fine ..
What FDD emulator did you use?

If the Betadisk work with HXC I think it will be a good solution and maybe I will make me a 128+2 with betadisk interface in future.
