Hi, I have 3ds XL with version ver 7.1.0-14u. I am about to order sky3ds from modchip direct. I am interesting in playing just the ROM. I don't want to other stuff like homebrew etc. do i keep my dsi version as it is or do i upgrade to latest version? please advice. http://www.modchipsdirect.com/sky3ds.html Will this card work fine? will this card also play all DSi(.nds) roms?
