I've been at this for way too many hours now. So, I had GBA games working properly as of last night running RxTools 3.0, which was the whole reason I was even attempting CFW since I have a Gateway. I chose to install them running under EmuNAND, but not in Gateway mode. After installing several of them, winding up with black squares on SysNAND, I formatted my SysNAND and tried to continue reloading everything I'd lost. Wouldn't work, so I replaced the dbs folder with its files and reset the data, and tried again. Still wouldn't work, so I uninstalled and reinstalled the AGB_FIRM patch. I think I broke something, or deleted the wrong file. Now, no matter what I do, even with a fresh SD card (I've tried three separate ones), with or without EmuNAND installed on them, even after formatting the EmuNAND with Gateway, and trying every build back to 2.5x, nothing will get RxTools to launch, much less install. My SysNAND is at 4.4.0-10U. I don't have any games with a higher firmware available to me at the moment, but I do have Cubic Ninja and a Gateway card. I also tried using Ninjhax to boot SysUpdater to update my SysNAND to 9.2x, but that just boots me back to the Homebrew Launcher every time. Are there any methods I haven't tried yet to update my SysNAND so I can reinstall RxTools? Literally every single guide I've seen so far relies on RxTools in some form or fashion. If I can't get that to boot, would I be able to use a retail cartridge with the correct firmware update on it? Not kidding, I've been at this for at least twelve hours total.
