So my younger brother went off to college and left his NDS lite. I saw that he had an R4 in the slot but there was no memory card. I managed to dig up a 16gb card and did a little research to figure out how to get the R4 working. I am not too sure what kind of R4 this is. All I know is that its an R4i and thats basically it. The cartridge just says: R4 i Revolution for DS (NDSI/NDSL/NDS) www.r4ultra.com I've also included a picture to be perfectly clear what r4 I have. I have no idea what firmware I need. I tried looking for my exact card but found only ones that said "Upgrade" underneath "R4 i" and those did not work, I only got the neverending loading screen. I called up my brother and he said he's not even sure because his friend set it up for him. Can someone please help? Is it because the R4i isn't SDHC so it can't use my 16gb card? or are all R4i's SDHC compatible? So confused here.
