Ah ok. Unlikely setup on a PC, but I understand. Well, even better that QPC can do both
... as well as sQLux, Q68
Ummm, no. "Both" in the sense of "byte-swapped" or not. As far as I'm aware this is a QPC-only feature.

Q40/Q60 Linux can also deal with byteswapped filesystems, not that this would be of much help.
Personally I think byteswapped images should be corrected, not used. But given the practical reality this is a good QPC feature.

Nope, I implemented byte swapping in sQLux years ago.

B*ll*cjs and never pushed that code

I am a little confused, the QUBide files from my QL-SD Interface, are read/write on Q68 using the QUB device, the BDI driver in Q-emulator and sqlux read the same file.
I probably do not know if bytes are flipped.

Oh, I remember what happened, the BDI version of the QL-SD driver would not read any of the test QUBIDE files I had so i parked the code in a branch to investigate later. And later still has not occurred (and branch is on a machine that is no more).

IIRC the BDI driver checks some bit in the master block to see if it's an IDE or SD image or some such and rejects the normal QubIDE images based on that.

None of those are IDE devices, so no byte swapping is happening. You get that for example if you try to read a native QubIDE partition on a PC.

Which raises the question: what would it take to have QubIDE be able to use the same .WIN files as QL-SD and everything else?
