Sat, 16 May 2015 23:08:07 -0700 Michael Pavone Adjust H32 vint slot in response to latest test ROM data
Sat, 16 May 2015 23:04:57 -0700 Michael Pavone First pass at emulating a vscroll latch. Titan's Overdrive demo seems to depend on the scroll value being latched early in the line before the HINT gets a chance to change it

Fri, 02 Jan 2015 13:47:34 -0800 Michael Pavone In theory, the Z80 core should work on 32-bit builds now; however, I suspect there is some code that cannot deal with most of the Z80 registers not having a native register so more work will be needed

Tue, 17 Jun 2014 19:01:01 -0700 Michael Pavone Partially working switch to having a vcounter and hslot counter in the context rather than trying to derive them from the cycle count. This should allow for more accurate handling of mid screen mode switches. Interrupt timing is broken currently though
