I'm curious as to why people usually recommend bending pins up. I've found it much better to cut traces on the circuit board. This way you can remove the EPROM and reprogram it easily. Cut traces are easy to reconnect if you cut the wrong one.
yea i like bending up because if i cut a wrong trace the board is done. i did see that A15 can be ignored on snes boards. not sure how i would go on from there though

As I understand it, LoROM uses A15 as a positive enable and doesn't use it on the ROM itself. HiROM uses A15 OR A22 as an enable, but it does route A15 to the ROM.
ok, so how would i wire A16-A19 on the board then?
