Fix 480i interlace. Vsync needs to be on exactly the right row, also the AN2 must be disabled by clearing bits 0 or 1 on dmactl.
346 04/04/2015 02:45 PM markw

Split the concept of hsync, vsync and composite sync. When composite sync used tie vsync high. The offset hsync pulse of pal/hsync is only present for 15khz composite sync. Remove rom selection since its unused.
339 03/27/2015 02:23 PM markw

Allow 64k carts to work. Switch keyboard to PS2 port 2.
337 03/26/2015 11:17 PM markw

The banks have a hole from 64k-256k, use this for the os rom, freeze and directory cache
333 03/26/2015 09:55 PM markw

Added low memory type 2 - for papilio and its 512k
321 03/15/2015 04:00 PM markw

Space reduction to fit onto a Spartan 6 LX9. Allow disabling stereo and covox. Also replace pokey non-linear table with a piecewise linear function rather than a LUT
319 01/12/2015 10:50 PM markw

Fix write through problem
296 12/13/2014 08:00 PM markw

Fix for hscrol and mode 8
295 12/13/2014 02:03 PM markw

Direct mode for control by usb firmware. Added mapping for 2nd, 3rd and 4th keypads. 2nd is on f4 to f6 etc, 3rd is as 1st but with control. 4th is as 2nd but with control.
291 12/13/2014 01:53 PM markw

Connect some signals used by svideo
