at-72g famicom cart connector flipper

for famiclones with the board labled at-72g. probably useable in similar famiclones.

If youre looking here i imagine you know how to mod consoles so i wont go through the how to.

this system doesnt connect expansion audio, so i added through hole pins for pin 45 and 46 so that you can easily re-enable it.

i havent tested this. but it should work. measurements are “super close”. it may need a need shaving. unless its super off im not going to update this design.

feel free to use the library on github. it is a full famiclone cart connector library for eagle that i made.

for use with rom hacks like megaman minus infinity. replaces chr ram. pull rom pin 31 and connect to pin 32. goes on the back of the pcb.
