Notes

same layout as Champion League (v220I, dual program, set 1) --- update 2016-05-18 from Roberto Fresca:

This set has two different programs splitted in quarters.
Both programs are intended to cover playing cards graphics (2nd quarter program), or cans (lattine) graphics to avoid some italian laws... (4th quarter program).
Seems that there's no way to switch between them. They are harcoded through the involved PLD's. Addressing lines lower than A12 are driven normally.

Main program ROM banking through PLDs...
