Okay, so this file format wasn't what I hoped it was. It's another hack. Lots of work to do.

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.

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.
