Required modifications to the dumper
You should hook up jumpers to change these pins to their required position, but still able to change back to regular cart dumper.
Everything is done to "chip" 1 only
The "chip" is referred to a 28 pin chip from now on, ignoring pins 1,2,31,32 - I.E. pin 3 on the 32 pin chip is now pin 1 on the "28 pin chip"
CHANGES
Connect pin 20 of the "chip" to pin 6 on the VB edge
Connect pin 28 of the "chip" to pin 8 on the VB edge
Connect pin 7 on the VB edge to Vcc (pin 8 on the VB edge) - for some reason the VB SRAM controller has problems giving power to CS2 quickly enough, so you have to manually power it.
