Legend:
--------
(s) means this pin connects to the System
(r) this only connects to the ROM
(w) this is a SRAM/WRAM connection only
AUD : these pass to the resistor network
CHR : these connect to the CHR ROM and/or fami's CHR pins
PRG : these connect to the PRG ROM and/or fami's PRG pins
WRAM : this hooks to the WRAM
CIRAM : the RAM chip which is on the fami board

`----------'
- 1: On some VRCVI carts, these are reversed. This affects some registers.
- 2: This passes through a small pulse shaping network consisting of a resistor, diode, and cap.
