I was under the assumption that with cfw and EmuNAND, you will be able to play games that require a higher firmware than the one you're currently on?It depends, 1.0.0 will get the Atmosphere CFW first, but you will be locked out of playing games that require a higher fw.
I don't thing the advantage of have a 1.0.0 will be that big. On the other side, I heard that 1.0.0 consoles are quite sought after on
ebay. Could be worth to buy from the money perspective.
Also, regarding XAW1000. Do the box and console numbers mostly match in terms of 1.0.0? I found another one, and the guy gave the serial number off of the console because he no longer had the box.
