Sorry, guys. I have detected an error on my GERBER. A21 byte signal is not passing through any LVC244A, so it is reaching with +5V pulse logic for the 64mbit roms.
This is the new version with a fix that passes A21 byte signal from romboard to one of the LVC244A, and the output is following the original destination pinout with the jumpers selection. Sorry
