There is an RX02 emulation in Bob's package (that I remember). The only
thing I can think of which might affect whether they are readable is
whether the disk images you have are sector-by-sector image copies, or
block-by-block image copies. If they were copied using one technique,
but read using the other, then you'll actually be mixing unrelated
sectors together to form a block.
I would have to check the source (or ask Bob) which technique is supposed
to be used to make image RX01/02 copies so that they work.

Umm... 8" is what pretty much defines RX02s... I don't know of an RX02
which was other than 8" (except for the advanced development RX's which
communicated with the controller via FDDI back in 1983 or so which I
got working using a modified DY handler).
