So i've spent almost 6 hours trying to get all this to work correctly. Most of my dead ends are at errors like The trucha bug error. Cannot set revision to 0 while downgrading. Well , i have homebrew installed, everything seems to be working mostly. I've followed at least 5 guides claiming to work for 4.3u No luck. So all in all im asking for help from my fellow GBAtemp members. I cannot for the life of me get any backups to work with any type of backup launcher. Always comes up with some type of error. Can anyone send me a link or guide me in the direction to a guide that actually works for playing backups on 4.3u Thanks for all your time.
