I want one that doesn't have a yellow screen, will have an early enough firmware for gateway and I'd like to know how difficult it would be to put in one of the 3DS capture bits myself.

I want one that doesn't have a yellow screen...
...will have an early enough firmware for gateway...
...and I'd like to know how difficult it would be to put in one of the 3DS capture bits myself.
That's kind of a crap shoot.
Look for any box with the copyright date of 2011 or 2012.
Find me somewhere that sells the capture card by itself and I'll tell you how hard it is to install it.
No date or code could help me with the screens? No one sells the capture card on its own? It's been a long while for me, I kinda forgot what my options are at this point.
