Rebuild of ZPU firmware to pick up SIO patches from Hias
374 05/17/2015 02:47 PM markw

Patches to improve SIO from Hias. Many thanks!
359 04/21/2015 09:48 PM markw

Add breakout board support. Pass clockin/clockout to pokey (untested).
358 04/21/2015 09:45 PM markw

Made the same as Robins version, which worked!
351 04/08/2015 07:58 AM markw

Simple memory saving support - to help debugging
348 04/04/2015 11:50 PM markw

Added Drive turbo selection. Fixed a few builds. Added which target is building to output. Run up to 3 jobs at once during build.
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.
341 03/27/2015 02:42 PM markw

Latest firmware and added papilio duo to build scripts
340 03/27/2015 02:38 PM markw

Add weak pull-ups on data lines for cartridge/pbi
323 03/15/2015 04:08 PM markw

EDBLL apparently works with lower drive strength - there are some crosstalk issues I read. Added GPIO lower drive strength. Removed 25ohm resistors.
