I spent a good chunk of the afternoon on this. Someone once posted the Neo AES BIOS traceroutes here, and it's helped me a great deal. This info may help someone else, so it's time to pay it forward.

Note- cartridge slot (”CS”) is numbered according to IC numbering designation, assuming same orientation as BIOS eeprom.
Note- U20 has inverted orientation to most other board IC’s. This guide uses accurate numbering for that IC.

BIOS eeprom pin Destinations

1 - 5V
2 – CS-27
3 – CS-3
4 – U6-3, CS4
5 – U6-2, CS5
6 - U3-3, CS7
7 – U3-4, CS8
8 – U3-7, CS10
9 – U19-19, CS11
10 – CS12
11 – U3-14, U19-18, CS13, U20-10
12 – U3-13, U19-17, CS14, U20-11
