Not again. Not again. Please, not again. On a whim, after yet ANOTHER failed attempt at installing Mario Golf - World Tour, I went into Settings, Data Management, Nintendo 3DS, Software on my SysNAND, thinking I might be able to delete the failed install from there, rather than booting into EmuNAND, deleting it, then having to reboot back into Gateway mode. It didn't show anything under Software after about a minute of looking for files. So, I just backed out and booted back into Gateway mode. My SD card is now empty. Not again. Dear infernal Loki, not again. I JUST got everything working perfectly (except Mario Golf) two nights ago. I have installed 95% of my entire ROM collection as .cia files two times now, each time taking about two or three days, working on it for hours every single day, sometimes until 4AM. It's all gone. I have to start over AGAIN. Don't make the same mistake I did. Stay completely away from Data Management on your SysNAND. I've never wanted to chuck my 3DS out of a window before, but, right now, that doesn't seem like a bad idea at all. Not again.
