I'm not. Not only could the GCW firmware possible be ported, but the GCW looks really trashy. And judging from video of an owner, is: The LE was supposed to contain 16GB storage (over normal 8) and 512MB RAM (over normal 256MB). His LE, of the first 40?, contained 4GB Storage (half the normal) and 256MB Ram. And the LE bezel blocks a portion of the bottom of the screen. All of the original 40 were plagued with issues, (if not all of them containing a misized bezel) and were nicknamed 'frankenzeroes'. It's like a quality control disaster.
With the X you're getting roughly the same specs in a better shell for about the same cost, it's just about the software.
I don't thnk you could get a GCW even if you tried. l've contacted the GCW creator regarding a purchase and never heard back from him.
I have a GP2X Wiz and really like it; thinking maybe l should have gotten a caanoo instead of the NGX.
