It's been a while that I've worked with a 28 pin rom with anything other than an nrom, but I think that the 28 pin roms and eproms all have the same pinouts. You can double check that using the information in this document:

http://nesdev.parodius.com/rom.txt

Using this document, you know which pin of the connector edge and which pin of the mmc1 goes to which pin of the rom (watch that many pins on the connector edge go through the mmc1 and therefore the mmc1 is where you use a multimeter to test those lines). For example, put a multimeter on pin one of the mmc1. Test to make sure that it goes to A14 on the eprom. ]]> http://nintendoage.com/forum/messageview.cfm?catid=22&threadid=6791 2008-03-24T19:28:32 -05.00 dave2236 6 http://nintendoage.com/forum/messageview.cfm?catid=22&threadid=6791 2008-03-24T18:10:06 -05.00 dave2236 6 So you'd need 27C512 as your EPROM.
