Commander X16 Hardware Changes for Proto #2

This video is mostly focused at the needed changes for programmers on the new prototype HW. It may also be interesting for those interested in some of the other features. There should be no code breaking changes before the end. Also, I recompiled Chase Vault by Matt Hefferman to work on the physical machine and show it playing with sound via the YM2151! You can play Chase Vault yourself in the emulator here: https://www.commanderx16.com/forum/index.php?/files/file/9-chase-vault/ Thanks for a really great game Matt!
