Hi, I've built several repro carts for the SNES with an AM29f040b, thet definately work:) There's a picture of a 'Little Magic' cart i made at; http://www.digitpress.com/forum/showthread.php?t=120604 /WE definately needs to be tied to VCC. Make sure the ROM image you are trying to use is exactly 512...

You need to connect #WE to VCC, not to #OE. Otherwise the flash chip will be in write mode every time a read is attempted. Make sure you re-flash the chip before trying again, you may have corrupted the data stored on it.

Kind Regards, Andy.
