Okay, so I recently received an R4i SDHC 3DS RTS card for my DSiXL. My DSiXL version is 1.4.5 so it's updated to the newest version. The website that I bought the card from says that it works with the 3DS, 3DSXL, 2DS, DS, DSi, AND the DSiXL, the one that I have. The website that I bought the card from told me to go the official site, www.r4i-sdhc.com, and download the latest firmware which is "R4i SDHC 3DS Kernel V1.79b". I downloaded it and put into the root of my card just like they say to. I had "R4iMenu", "moonmemo", "moonshl2", "R4.dat", and "game", with a total of five game in that folder. When I tried to play it, after clicking the game icon, it just took me to a black screen, and never did anything. Later, I tried a different firmware, which was also suppposed to work on my DSiXL. It was "Wood R4i Gold V1.64". I put everthing into the root along with a "game" folder, with the same five games. It loaded up and I got the R4i screen with a way to browse different files. (they looked like R4i menu files and such.) But none of the games were there. I have no idea what is going on. if anyone has an idea, it would help. (And I know that its not a fake card, because it worked with the second firware KINDA, and I've ordered from the same site before.) Thank you.
