With this Homebrew, you can install and uninstall Adrenaline as well as the custom LiveArea theme easily. This release installs “adrenaline_fix2.zip” but you can manually replace the files inside this vpk if there happens to be an update. If you find any bugs please let me know. 
Download: AdrenalineEasyInstaller.vpk (v1.02)
Adrenaline EasyInstaller is updated to v1.03 and open-sourced now as well! Yes, I keep my promises!
You now no longer need to manually download and place the 661.PBP firmware file. Everything is automated now!
Note: If you already got Adrenaline up and running you don’t need to do anything!

Have fun 🙂
