New GPIO layout for PBI implementation
Keyboard as joystick1. Escape to exit menu. Disable keyboard gpio when gpio off!
Merged in first cut cartridge emulation support from Hias. Excellent:-)
Start connecting up switches/gpio again. So far joystick... Also connected antic refresh to sdram.
Added ZPU - it works. Need to add GPIO joystick back in...
DE1 working with SRAM against common core. Plenty of features lost!
