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

285 12/11/2014 10:36 PM markw

Share the USB PS2 override logic. Wire up USB to controllers on the MCC216

283 12/07/2014 11:27 PM markw

Capture SIO commands using a hardware state machine - too time critical to easily merge with USB polling otherwise (without much code refactoring...). Now drive emulation works on MCCTV with USB:)

274 11/22/2014 11:20 PM markw

Fixed warning

273 11/22/2014 11:20 PM markw

New mode for full OS and no basic rom

272 11/22/2014 11:20 PM markw

Fixed warning
