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
