CTRG1 = Graphics Roms, S1, M1
CTRG2 = Program Roms, Sound Roms

NOTE: On CTRG2-B, The "A" lines start at "A1". If you trace this on an actual cart, you will see that this is actually "A0" (A0 - A18).

These are from a very hard to read copy of the schematics, so I hope that I got the pin names correct.
