This is for 27c010:
Pin 1 is VPP and should be tied to GND imo.
Pin 2 is connected to hole 24 (A16)
Pin 24 is connected to GND
Pin 30 is NC
Pin 31 is P (should be connected according to datasheet). GND should be fine.
I had cases where when I left P floating the EPROM wouldn't work. So make sure you read the datasheet for it. ]]> http://nintendoage.com/forum/messageview.cfm?catid=22&threadid=180901 2018-03-22T14:41:45 -05.00 Kamel85 7   ]]> http://nintendoage.com/forum/messageview.cfm?catid=22&threadid=180901 2018-03-22T14:40:42 -05.00 Kamel85 7
So for the chr its just solder down as is for a 27c010, and for the prg (also 27c010) i need to ground pin 24 and route pin 2 to the hole under pin 24? ]]> http://nintendoage.com/forum/messageview.cfm?catid=22&threadid=180901 2018-03-22T06:39:28 -05.00 Kamel85 7 https://wiki.nesdev.com/w/index.php/SxROM

iirc the chr pinout uses the usual nintendo prg pinout. if your chr is over 128K it'll take extra work to install. ]]> http://nintendoage.com/forum/messageview.cfm?catid=22&threadid=180901 2018-03-21T19:00:37 -05.00 Kamel85 7
