SMS direct to Genesis
Posted: Thu Feb 18, 2016 1:14 am
Hi there, Im trying to get a simple 32Kbyte SMS ROM to run directly on the Sega Genesis.
From what I understand, I need to ground B30 (!S_RESET) and if I want support for the pause button, I will need to connect B9 to VCC, B10 to GND and Pull B11 high, with a button connected between it and GND. This is based on Raphnet's schematic for a pass through cart from SMS 50-pin to 64-pin SMD here. And also based on my probing of an official SMS cartridge.
Here is my schematic that I am not sure of.
I was trying to make a test cart.... but realized only my Genesis 3 and Nomad are working right now...
Does anyone have corrections for my schematic?
