Carts with P0 and P1 roms?? ODD / EVEN?? High /Lo rom banks??
« on: December 24, 2014, 08:01:35 pm »
Hello all,

In opening up quite a few carts while looking for donner cart for "Super Famicom Wars".
I came across some carts with 2 roms inside. One marked P0 and one marked P1.

Are these ODD / EVEN or HIGH LOW rom splits? So you could use 2 X 16mbit chips to run a 32mbit game??

Did some searching on here and web for P0 P1.. but didn't find any info.

Thanks in advance.

D.

It all depends on the exact connections in the cart. Grab a datasheet for each chip and find out the pinout, there should be a chip select signal to control which chip does respond.
