can for example give command:
debug set_watchpoint write_io 0x8 {} {set ::MyValue ... with this custom command:
wp_after_input 0x8 {} {wp_set_input $::MyValue}
... in theory it works well ... command at $[format %X [expr [reg pc]-2]]"}

control the individual bits by using keys 0-3 and see easily how it is done. Instead of being impressive, ... that results either B or 0. On VDP we can't do "IF A AND 1 THEN R=B ELSE R=0" approach because these are areas and VDP does not have "IF". This is why we do AND A(0) against all bits of B. Result ...

Also A0 to A13 failed also.
Great stuff. I've ...
