CPC ROM emulator using a Raspberry Pi Pico

[RetroDave]

This looks like a great project.

I'd be very interested to hear how version 2 is progressing, especially the disk controller support. 

It would be great to have a cheap and simple to build floppy emulator. Existing CPC options seem limited and expensive. 

The memory expansion would be good too if that's possible. 

There are some similar projects for other platforms that are Pico based like the A2Pico card for the Apple II and PicoMEM for ISA PCs.
