Fork that flips the screen

[zoe-vb-cs2]

Hello I recently found and compiled a fork of linuxloader2 found at https://github.com/1640675651/nspire-linux-loader2 This does all the screen mirroring that would be required to rotate the screen the correct way to boot linux with the correct rotation on newer models. However despite this it hangs on boot now unlike the one in this repository. What could be a fix?
