Thank you! I should have done that when it said I could, but stupid me thought I had already switched out my original SD for my larger one before I started, oops...
I'm at the last step of Part 5 Section I. I don't have enough space on my sd card to put emuNAND_original.bin, I'm 436 mb short. Is there anything from previous steps that I can delete to make room? In a previous part, it was said that I could remove sysNAND_original.bin. Can I still do that now...
