Got 1 of these i need to sell. Its brand new and unused.
Tested it when i had the DS and it works fine, never needed it though as i had an R4.
Really nice card though, supports SDHC so theres no upper limit on memory card size, unlike the original (not cloned) R4 which only supports upto 2gb.
They're about £24 on Amazon including the postage so i think the asking price is fair, considering its absolutely brand-new.
It'll be posted the same day as payment is made, if its bought tonight i'll post it tomorrow to be with you Tuesday.
Payment by BT or Paypal gift (or paypal and you pay the fees)
Price includes p+p
