Umm sure but it's nothing but what's included in the github zips of HBL and Loadiine:
apps.zip
What I recommend instead is:
Get SD:\wiiu\apps\homebrew_launcher\ from here:
https://github.com/dimok789/homebrew_launcher/releases (newest)
Get Loadiine GX2 v0.2 (because it's stable) from here:
https://github.com/dimok789/loadiine_gx2/releases/tag/v0.2
Put it on SD so you have SD:\wiiu\apps\loadiine_gx\
Then copy this folder inside your apps folder and rename it to
loadiine_gx_nightly then open up the folder and edit the xml with a text editor. Change title and/or description to "Loadiine GX2 Nightly" so you know which one is stable and which one is newest nightly when you're inside the HBL.
Delete the *.elf file in the nightly folder.
Get the newest nightly from here:
https://github.com/dimok789/loadiine_gx2/releases
Put the *.elf file from the zip in your
loadiine_gx_nightly folder and rename it to
loadiine_gx_nightly.elf in order to have two versions of Loadiine on your SD card to try around with.
This is also a good tip since there are some games that are reported to work better with 0.2 while a few others work smoother with 0.3 nightlies.
Edit: Don't worry, since they're "the same app" (Loadiine) in both cases you can of course continue your savegames from one to another.
That means for games that run like a charm in both (0.2 and 0.3) like Mario Tennis: Ultra Smash it's no problem to start a savegame in 0.2, continue in 0.3, go back to 0.2 on next reboot and continue from there and so on.
Until Loadiine changes the way it handles savegames in a nightly there's no incompatibilites.
