Hello, I have the first model 3ds XL and I intend to play my backup roms (both 3ds and ds) from an SD card. I am uncertain which flashcart has the best features / options. I am looking at the r4i 3ds deluxe and the Gateway 3ds. As I said I am unclear on a few things so please let me know if I am correct in the following: * The gateway only supports 3DS code, so it will not play the ds roms? * Neither support saving for 3ds games, but the r4i supports ds saves? * R4i 3ds deluxe supports online play but not the gateway. * both accept SDHC cards. I don't know any other questions to ask, but I am sure they are there. I have read through a lot of the faq's and I believe I have my facts straight, but again, I would rather be clear. Thanks for your time.
