Hey all.

I recently picked up a Generation NEX Arcade stick and think it's actually pretty great. The only problem with it really is that as it's wireless, it can only be used with the rather crappy NEX Famiclone and not real hardware. To address that, I'd like to add in an NES controller cord to the stick, but am wondering if this is even possible.

Here's the info I know about it.

The main board has a gloptop for a 4021 with no obvious places for soldering wires to.
Looking over the board there seems to be test points scattered about, but nothing is labeled.
Looks like its common ground as the Joystick microswitches are daisy chained and so are the B and A buttons.
It's powered by four AAA's so 6v total. Would NES VCC 5v be enough to satisfy the stick?

Would it be possible to run a cord and control the stick and maintain it's wireless functionality? The wireless is great for use on the NEX and I'd like to keep it intact if I can.

I've got lots of soldering experience and have done several NES related mod projects in the past.

Any help is much appreciated.
