Its a simple one byte patch in the machine code routine that sets up the RAM hooks. The patch results in the RAM hook at $019a-019c (Get next command) being set up to point to a slightly higher address.

By default Xroar doesn't report illegal op codes. :?
I was unaware of that, I assumed that any errors would be logged in "stderr.txt" (where the only warnings I have concern the lack of joysticks). In any event, I was addressing any concerns anyone using the archive's copies may have had in running them on XRoar.

Surely my patched version is the best bet? You are getting the 100% original game without the illegal op code bug.
It was not my intention to slight your effort in creating patched the files, I mentioned Ciaran's wave files because the thread was originally about creating wave files from certain CAS files, and at the time I did not realise that your patched version also contained wave files.
