I just received an R4 Revolution for DS cart and I can't make it work with my Nintendo DS phat. I am using a 1GB Kingston micro SD card, my PC recognizes it, it is formated to Fat32 but also tried it with FAT, and I can never get it to work, when I start the DS, "Couldn't find the SD/TF card" message pops up on the upper screen. Tried newest and older firmwares, official, wood, always the same result. Any ideas what am I doing wrong? Error message appears right after the health and care thingy. Also tried formating with SD card formater. EDIT: Forgot to mention that I even put the paper under it, still didn't help. Post Merge: [time]1442557233[/time] Finally got it to work! Problem was, I was pushing the microSD card in too deep into the R4... and was not making contact I guess, if I leave a few millimeters out hanging it is working fine! Thanks for the help! Hope this helps somebody else as well!
