I have the R4i-SDHC WIFI 1.4.X. I have an sdhc card which has only the firmware that they have from their site (v1.80b) When plugged into the DSi XL, it shows up only if it is inserted when the DSi-XL is on. When I click on it, it says, An error has occured. Press and hold the Power Button to turn the system off. Please see the Nintendo DSi Operations Manual for help troubleshooting. What do I do? I know my card works on 1.4.5, because there are many people that I have seen in videos on 1.4.5 and it works fine. My card is legit, I bought it from the official website (r4i-sdhc) and I did the truth inquiry thing and it says ok. Thanks, Oalecj Edit: Here's the exact card... https://imgur.com/a/gWlmPE Edit 2: It actually worked on another firmware, but I'm not sure what that was since it was a while back.
