so, I followed this guide:
http://www.dbwbp.com/index.php/13-elect ... -snes-cart
to upgrade the SRAM of a 1A1M-20 board from 16 to 64kb, and I'm getting a WEIRD problem
Anything that gets written to the SRAM is offset by 4.
I fill zeroes, I get 8kb of solid 04s.
I fill FF, it comes out as FF, because that's as high as it goes.
What might cause that?
Could the capacitor next to the SRAM have been damaged when I mounted it on the reverse of the board to fit the larger SRAM?
