Sorry, two WIPs in one day. Got excited and couldn't wait.
Changelog:
- ADDQ, SUBQ shouldn't update flags when targeting an address register
- ADDA should sign extend effective address reads
- JSR was pushing the PC too early
- some improvements to 8-bit register reads on the VDP (still needs
work)
- added H/V counter reads to the VDP IO port region
- icarus: added support for importing Master System and Game Gear ROMs
- tomoko: added library sub-menus for each manufacturer
- still need to sort Game Gear after Mega Drive somehow ...
The sub-menu system actually isn't all that bad. It is indeed a bit more
annoying, but not as annoying as I thought it was going to be. However,
it looks a hell of a lot nicer now.
