Yoh'. So, just a quick forward of "I'm not stupid, just stressed, over worked, and scatter-brained". k? k.
Here's the deal. I have a N3DS, 9.0.0.20 FW. I'm running PastaCFW 1.3b7. I formatted my mSD card, got rid of my emuNAND, etc. Put all the files on the card. Good to go.
If I just load the CFW, it doesn't get ARM11 access. So I load brahma and install that exploit, then load PastaCFW. Until I did that I got errors trying to install cia files about some AM(?) process or something. Guy in second video didn't mention that and I had to find out via the "outdated" one above it, which I ignored the first few hours of working on this as its "outdated". Also that info isn't in the OP instructions anymore.
So I got that far. Installed some 3DS cia files. I used FBI to install BBM, FBI, and some other cia files. They work.
Installed some GBA games (the reason I deleted the precious emuNAND)... Black screen, then system reset. And yes, for the record, others have installed them without issue. They're also region-free.
I think there is an error in my process. I can't figure out where exactly I'm messing up, so input would be nice. Halp?
If I figure this out, I will write a succinct tutorial. Fo' realz.
