Flash cart stores

Hey guys I have a Nintendo DSI v1.4.5u and had a blue r4i v1.45 revolution cartridge but was a clone and I am planning to buy a new flashcart, it's the r4i-sdhc 3ds rts precisely made for the dsi with version v1.4.5 so If any body knows any flashcart store in dubai tell me b/c I am in dubai right now.

I think the NDS 3DS R4i card works with all models, but I'm not sure since I don't see any results with my current cart, I will also like to know what kind of flashcart to buy at that store front... I also have a DSi at 1.4.5U Firmware that I could use, but mainly my DSi XL is the one I like most because of the resolution, I have one at 1.4.1U firmware...that's all I know.

ok tnx and any other comments are welcome

the R4i Gold 2015 works with all systems.. which is not bad for a "Gold Card"
