Of course, changing the IRQ enable may immediately change the IRQ line. Signal if so.

Interrupt enabling works the other way around I think, and both registers with only one bit defined should probably return '1' in all other places?

Gave the Microdisc a clock signal, added just enough of force interrupt to avoid a spurious belief that a type 3 command has started.

Okay, so it looks like both ROM paging flags are the opposite of what I previously had.

Any Oric-format disks that are inserted now make it all the way to the Oric, along with a request to emulate the Microdisc. It has received a copy of the ROM. The ball is entirely in its court now.

Extended analysis to spot IRQ and NMI vector changes, for titles that simply adjust those then exit. Ensured Oric emulator can type and load quickly on an Oric 1 just as well as on an Atmos.

The emulated Oric now has access to both versions of the BASIC ROM and picks between them based on the static analyser's recommendation.
