hi everyone.
just looking at the snes cart connector pinout, it apears to be 8 bit (correct me if i'm wrong). so is it possible connect a 16 bit eprom like the 27C160 to the snes cart connector? or do you some how just leave the I/O pins from bit 8 through to bit 15 unconnected?
Best regards
Declan

Hardware means nothing if you don't have good software.

Looking at the datasheet's description of that particular chip, you tie "BYTEVpp" to low, and use "Q15A-1" as the lowest address bit. This chip can then be read in an 8-bit fashion.
I assume this means,
cartridge bus A0 = Q15-A1 of the chip
cartridge bus A1 = A0 of the chip
cartridge bus A2 = A1 of the chip
cartridge bus A3 = A2 of the chip
obviously, with an 8-bit bus, Q8 through Q14 would remain unconnected.
Q0 through Q7 is your data.
Again, just search for "27C160" in Google for the datasheet if you don't have it already. It explains it quite well, but I want to kick in the nuts the author who decided to use VIL and VIH for H and L, and then arbitrarily call CS "E" and OE "G".
