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.
Pass s4_n,s5_n and cctl_n through 6502 timing adaptor. Only accept request at start of cycle.
Patches from Hias. Fix timing to allow The!Cart to work. Start of PBI work.
Added some glue to talk to 6502 style bus with phi1/phi2 etc. Connected to GPIO including phi2 out. VBXE carts not running more reliably. In theory other carts such as The!Cart etc should work now, need to test...
