I have RocketLauncher on my LB setup working perfectly but only for a small number of games, notably Gamecube games like Resident Evil 2 and 3, using an old Dolphin emulator for audio compatibility and bezel reasons, plus a handful of 3Ds games that use both screen during gameplay requiring bezels and some Daphne titles that can run with bezels.
I guess I could remove it and won't lose much but since it just works and took me years to make it function at the current level, I see no point in removing it.
