The quiz is open to all members except staff.
We decided to go down the GBA route so long time members with the forum from the start have a better chance to win, as they will have followed the GBA scene closely, wheras newer members are more likely to be more DS orientated.
The ItouchDS can run Sakura firmware, has SDHC and cheat support and is an all round, great budget card. With Sakura fw it's basically an M3 Real.
With the newer firmware the card is also very stable, and we will be updating the ItouchDS review to reflect that.
I was lucky enough to have a few of these cards some months ago, and then, as well as now, I haven't encountered any of the problems mentioned in the review.
We haven't finalized the questions just yet, but once we have done so the quiz will be open.
Good luck!
