Oh god damn it all...
The only reason I even halfway considered going with CFW at all -
AT ALL - was for the promise of being able to launch GBA and DSiWare, particularly with what I already legitimately owned, let alone for some of the VC out there that started to show up including some really choice games for the respective system(s).
The only reason I even thought to use RxTools in the first place was for the promise that I could re-use the same emunand I already had with the Gateway 3DS.
With the Gateway, it was literally just... run the DS installer, go into the settings, launch Gateway mode. And now, with cheat hunting on top of it.
So far, nothing about CFW is working as it should for me.
After a really obnoxious process to even find out how to turn off the antivirus long enough to get the supposed required binary files, moving them to the 3DS SD card, re-starting the steps I'm familiar with, it did actually launch the emunand to my surprise. But as soon as I tried to launch either the GBA or the DSiWare, it immediately gives me "An error has occurred" on the black screen, and the Home button no longer even works. forcing me to have to turn off the system.
Please remind me again, why everyone and their dog here keeps acting like CFW is so easy on the 3DS? I am seriously so aggravated right now, and wondering if it's even worth putting any more effort into this hot mess.
