The Playstation memory card protocol can be found here:
    http://utils.zophar.net/library/pad%20and%20mem%20card%20data.txt

The problem is, the 8MB cards are "paged" - the most common method to switch
between pages is to use the joypad (hold select and then fiddle with R1, R2,
L1, L2 etc). You'd still get access to the first megabyte (15 PSX memory
blocks), though.

You might be better off using the 1MB cards instead. Remove the case and
solder a different connector onto the edge connector. This should make the
cards a bit easier to swap. Or you could have a look for a device called the
"Playsaver". The construction info shows you how to make a memcard connector
out of an old IDC edge connector.

HTH.
