1. The files "Private" and "boot.elf"; do i need to keep those on my sd card or can i take em off. 2. Another file appeared on my sd called log. can i delete this? Thats it. Thanks!
The "private" folder may contain some save data or channels if you have moved any to the SD card. If you didn't have a private folder before you started installing homebrew, you can safely delete it.
