I'm trying to Homebrew my Nintendo Wii, and a 2 GB or under SD card is required. However, the Wii will also recognize 4 GB cards if enough junk is put on it. I'm attempting to do this with my Optima 4GB SD Card on Mac OS X, El Capitan (v. 10.11.6). After formatting it to ExFAT, I put a 1.28 GB file on the card. Everything went smoothly. The next time I tried, though, I got an error saying that there wasn't enough space, even though there's plenty left. Here's a screenshot of the SD card info. I know that this is a common problem with USB's, but is there any solution for SD cards?
