Just to ask the question, in terms of ADFSS development, has it moved beyond ROS 3.11 in compatibility now, I'm using 2.20, is this the highest version I can go to?

If an ADF is generating a disk error under ADFFS, it's probably a truncated image and missing the last few sectors.

Not sure what you mean with regard to compatibility, are you referring to the games it gets running on the Pi?

The latest publicly available version is the London Show 2.52 build

In terms of the A3000 running RiscOS 3.11, I'm retro :)

Still not quite sure what you're asking. ADFFS has always been compatible with RO3.11

Ah so it's only Pi that has the RISC OS 5.23 requirement and you're maintaining compatibility with the real hardware and their respective OS versions.

As per my post yesterday regarding Page Zero relocation, all machines after IOMD will require a High Vector build of RISCOS for the JIT to work.

On IOMD, as High Vectors aren't possible, the JIT interprets LDR to trap Page Zero reads and it's obviously not relevant to IOC as the games aren't being managed by ADFFS.

ADFFS is essentially just a floppy emulator on IOC, on IOMD it emulates the IOC chipset and on StrongARM and above it acts as a Hypervisor.
