Im using Blaster Master to make something and I forgot it was an SL2ROM, so im taking a look at its pinout. It turns out that SL2ROM is an SLROM board, 256 PRG 128 CHR BUT the prg uses a mask rom pinout and the CHR uses an EPROM pinout.
SL2ROM CHR:
5+ 1 32 5+
A16 2 31 5+
A15 3 30 5+
A12 4 29 A14
A7 5 28 A13
A6 6 27 A8
A6 7 26 A9
A4 8 25 A11
A3 9 24 /CE (Attatched to cart edge 21)
A2 10 23 A10
A1 11 22 /CE (Attatched to cart edge 65)
A0 12 21 D7
D0 13 20 D6
D1 14 19 D5
D2 15 18 D4
GND 16 17 D3
So aside from this, I know that SF1ROM uses an EPROM pinout for the PRG. I wonder why they did this?
Also why is the chip revision number the same for the CHR? (NES-VM-0). When they did that with Bases loaded (SFROM), they had a different PRG revision for SF1ROM (NES-LD-2)
