I am a reseller in Holland for different products and I would like to buy R4 cards for nintendo DSI. For days Im searching for original R4 cards that support Nintendo DSI, SDHC and RTS. But it is very hard for me to find a supplier or manufacturer that has the original R4 cards. Everyone is blaming each other that they have the original and the rest is fake/clone. The following website http://www.linfoxdomain.com/nintendo/ds/ tells me that the R4 of r4rts.cn is the original DSI card. But when I contact this manufacturer I get a reply from the following website: www.gamekool.com They represent themself as the general agent of R4. But with a google search on this company I find some bad reviews and also of the blacklist of gbatemp. Is this maybe also fake or scam? Or can I trust this company? I am interested in the R4 cards because the market on Holland ask for this brand. Can anybody help me out with a manufacturer/supplier, that has original cards and delivers fast? Thanks in advance.
