I have 2 G6 lites and 1 regular G6 all which were purchased right away and NONE of em have problems. I was constantly playing my G6 Lite to the point where I put 6 hours a day on my kit. Never have any problems, no games mess up, from Sonic Rush, Tony Hawk, Animal Crossing, NSMB, Tetris, Phoenix Wright...the list goes on. I have NEVER had any problems at all. No corruption issues, no games not working...sad thing is I run a production company and so the kits sit in a bowl for when work is slow or there is a break people can play games.....and yet nobody here has said "Yo HC, this cart is corrupt?" But I do try to hire people who are fairly competent so that may help. Bottom line is I make sure one cart is MINE which means no touchy touchy for anyone else and right now one of the G6Lites is MY CARD. I just got in some new kits like the M3lite and everyone knows the rules, I need to test em before they can touch em but all I can say is I have had both G6 lite products at launch and never had any problems at all even under extreme playing. I did have one guy who worked for me that opened a Pepsi upside down and then decided to go on the web and boycott Pepsi saying the product was faulty....sadly I had to let him go.
