My Eprom cart's do not work. Since I am not using a socket, I am not scratching the PCB. I am lifting the legs of the eproms.

Like the picture above, is how I wired my cartridges.

I KNOW THAT MY EPROMS ARE PROGRAMMED CORRECTLY. ( I programmed them, verified them, and re-read them and played the image from the eprom on Snes9x, and I got my friend to read the eprom at his house too so I can guarantee you that the eprom is indeed programmed with data, and that data is tested working.) The header was removed with Snestool and I checked the buffer on my willems programmer to make sure there was no header, it is also 1048576 bytes, so again, eprom is not the issue.


I used phone cables and ripped them open and use the insulated 22gauge? wire from inside them as wiring. I used a Lufia rom (in a Xardion NTSC cart) and a Dragons Lair rom (inside an David Crane's amazing tennis cart).

Is it my wires? What kind of wire should I use then?

Thanks

Your wires are fine, it looks like a really clean way of doing it

Find a pinout of the EPROM chip, and of the SNES edge connector. Then use a multimeter to make sure every pin matches and goes where it should

Thanks tom for the help on IRC.

New question, A16, 17, 18, 19 and *0E = ???? on the edge connector

Your game is LOROM, so A15 on the cart is ignored. BA0 goes to ROM A15, BA1 -> ROM A16 and so on

OE means Ouput Enable and is the same as RD for read
