I'm getting an R4, but I don't know which SD card I should get. There's so many, and I don't know which will be compatible with th R4. Can anyone help? :ph43r:

Ummm, A MicroSD?

You may also want to consider other possibilities like the m3 DS real. Since the R4 is the cheapest, it can't be the best. If it is then the system is flawed.

I don't know anything in R4DS or M3DS Real either, I know only DSTT, in DSTT, you only need one skin and first delete the default skin and replace it with another skin.... The SD card is MicroSD... DSTT has Soft Reset, R4DS also have Soft Reset, DSTT has..... DMA Read, If anyone don't know DMA Read is, its Direct Memory Access, If DMA is not on, the game might slower like in No$GBA, DSTT and R4DS has cheats, but R4DS will request the user to create a save and load the Cartridge, DSTT AUTOMATICALLY creates a save and after that, the game is loaded, R4DS can handle many skins, sorry for the offtopish
