The light is for debugging purposes. I don't think it matters. I helped someone else prep for GW and apparently he got the same thing, but it installed nicely :]
well I think I was wrong, I went to the test on GW menu and it lightered XD but thanks again XD
btw 2Hack, do you know if it's possible to choose the language I want to boot the game on GW ?for example if I use an eur rom, I can't made an US 3DS menu on every language that have there to boot in on that one õ3o
