What's New:
- Fixed up DACs, incorrect channels were sometimes being set, and some ports were wrong.
- Added "-nodelay" startup option to the docs. Totally forgot about it, my bad.
- AY will now be reset with nextreg 6 (bits 0-1)
- Fixed a CSpect crash when a streaming file wasn't there. (esxDOS emulation)
- I now try and detect if you've accidentally provided a ZIP file instead of an SD card image.
