Great, thanks...

I found this but I assume it's incorrect?

Code: Select all

I/O 2 =  Decoded I/O block 2, starting at $9130
I/O 3 =  Decoded I/O block 3, starting at $9140
Another question, each BLK is 8k but a0-a13 is available on the cart port, when would I need a13?

IO2, IO3?

Help me refresh my memory, it's been 20 years :)

IO2 and IO3 is not an address range like BLK5, right?
Or does $9131 also puts I/O 2 high (it is active high right?).
