So I'm planning on buying myself a Nintendo 3DS. Searching for flash carts in my country, I've only found a few R4 ones. Thing is, I've heard many are fakes, and if you could please help me by telling me which one of the following is good, that would be great. Those are the options: -"R4i 3DS WiFi" -"R4i RTS Dual Core v1.45 v10.6" -"R4i RTS Dual Core v1.45 v10.1.0.27" I know they would run DS games only. Thanks.
