Hardware/nes specs:
So to start off I have a GQ-4x4, with the 16 Bit EPROM 40/42 pin ZIF adapter. (Not using the adapter atm) using USB only, no power adapter.
I ordered a bunch of Eproms, namely M27C512, AM27C010, M27C1001, and others. The ones listed are the ones I have in hand.
I have the CIC disabled(Pin4) on my NES front loader, and a Blinking light win installed. All other OEM hardware. Works with any original game I have.
Famirom for rom splitting to bin files.
Doing the work
I picked up a copy of Wheel of Fortune (Aorom) with a cracked case for cheap. I used http://bootgod.dyndns.org:7777 and found Jeopardy! (RevA) to be usable for a test run. Both of which only have a PRG to write. I used Famirom to spit out the .bin file of Jeopardy then imported the bin and used USBPrg (GQ-4x4 Eprom app) to burn an AM27C010 a 1m(128x8) chip. Did a blank check, wrote successful (I think). I'm thinking great, lets get the PRG off of the Wheel of Fortune and replace it with our freshly written AM27C010 with Jeopardy on it. Tested it and nothing, just a purple blinking screen. (Without wiring anything). Put the original Wheel of fortune PRG back on and test it, booted right up to the original donor game like a champ.
Confused am I doing something wrong
Puzzled I looked online and found docs online about wiring axrom boards Link here ( http://poorstudenthobbyist.blogspot.com/2014/10/making-your-own-nes-reproduction.html )
Wiring More specifically the part where it mentions 32pin eprom wiring for axrom boards about a 1/4 the way down:
128KB PRG ROM:
Bend up pins 1, 2, 24, 30, and 31. Connect pin 1 to hole 30, Connect pin 2 to hole 24, Connect pin 24 to pin 16, Leave pin 30 and pin 31 disconnected
256KB PRG ROM:
Bend up pins 1, 2, 24, 30, and 31. Connect pin 1 to hole 30, Connect pin 2 to hole 24, Connect pin 24 to pin 16, Connect pin 30 to hole 1, Leave pin 31 disconnected
Verified continuity to wires/pins/vias - I tried both of these wiring methods with no results.
Did I not wire it correctly, does it need wiring, or did I write the chip wrong. I left everything default when burning the chip and importing the bin file. Even did a blank check after I wrote it and it did indeed have data on it. Can provide pics if needed of my hack job of wiring or anything else. Someone point me in the right direction?
I'm trying to burn "Jeopardy! (USA) (Rev A)".
