* new machines marked as NOT WORKING
Play TV Bass Fishin' [Sean Riddle, Peter Wilhelmsen]

also some debug code to help figure out how video banking / segmentation works in the mode used by boxing in places, and this in places and some PAL machine clones of what we have because they're useful for figuring out register use.

* mode notes (nw)

Star Wars Saga Edition also seems to be making use of additional opcodes, meaning it could also be Super Xavix, or something in-between (unless they're
caused by the bad dump, but it looks intentional)
