Quicker and easier would be to try reading from the AY [i]data[/i] port. Floating bus => 128K, same as AY [i]register[/i] port => +2A/+3. Might make debugging on some emulators harder though. -

Trust me not as I'm not that techy, but I think the +2A and +3 can't use the floating bus trick to know if the ULA is drawing the border or not. That's what made many games such as Arkanoid not work with those models. -
