Work in progress, it's going to take a while. Layer2 is now wired, and sprites are buggy. Tiles are not implemented at all, and it won't be able to boot NextZXOS for a while because it requires FAT handling. Clock speed is kind of random right now, needs to be worked on to match a real Next. It has no idea about loading NEX files at all, although all things considered, it's a pretty well specified format, shouldn't be a lot harder than loading traditional snapshots.

BUT, it implements NEXTREG and it can correctly composite the existing graphic mode layers and sprites in the specified order. Z80N emulation seems to be good, with a test harness to match Z80N behaviour against CSpect across all extended Z80N instructions.

I was able to boot it using a +3 ROM set, and used Layer 2 to paint a red pixel using the Next machinery and it worked. A fully-featured Next is probably months away.
