Hiyo, didn't see this until right now. Region switch for the cards, or no?
Just an fyi. You don't need a region mod if you plan on using a Turbo Everdrive as you can play US and JP games on an unmodded console. This is actually the best and cheapest way imo unless you have to have and play the US HuCards.
This is why I never modded it.
Also, someone asked if it's been recapped - it has not. IIRC, the Duo-Rs are safe. I mean yes, my EE background tells me to recap EVERYTHING, but it's not a necessity like the standard Duos and Expresses.
