Re: 29f160 wiring help
Ground the unused address lines.
Unused inputs should always be connected to something unless the datasheet specifies that an input is internally pulled up or down. And I haven't heard of a commodity flash memory with pullups or pulldowns on its address lines.

Re: 29f160 wiring help
Ok, ty... At that moment i've got :29L323DT 32mbit (4Mx8/2Mx16),29F160BE 16mbit (2Mx8/1Mx16) and 29LV800CT 8mbit (1Mx8/512Kx16) all TSOP48. How to write the game... Can i Just write it in one chunk or have to split and use multiplexer?
Re: 29f160 wiring help
Look at the datasheet, if it can run in 8-bit mode, you don't need a multiplexer.
HOWEVER. The letter "L" indicates a 3V part. Do not use one in your (or anyone else's) SNES without adding additional protection parts, 3V ROMs will damage the console and/or be damaged by it.
