well you can still do a couple things, like open your nes up and check pin 3 and 9 see if a resister is soldered there(there is alot of pics of it on the net to identify by) and if you have that then you have to get your converter modded, if you can get it to stick right and want to test without soldering i guess you could try taping hte wire in the right spot on the converter but i deffinatly wouldn't suggest it on the board i feel it's kinda risky on the converter itself personally but for all i know there could be no risk, i mean you originally put the everdrive in the wrong way and tried to boot it so i doubt the wire barly crossing another pin would cause too much damage. your best option would probly be to check the pins inside the nes but i KNOW you need the converter modded because the pin that uses exp6 isn.t used in the converter, it's just unlinked to anything on both sides
