IMHO P2/P3 beeing inverted should not cause a problem as long as the register default value is $ff. This one should cause a problem only for TED reading the default bank.
But in case of Dream World the demo starts up in the highest memory bank (according to the control register at $fd16 as it's $ff by default) which is 7 for 512k then writes 3 to select bank 3. It does not care about inverting physical lines.
