you can base on this layout:
https://github.com/dimok789/homebrew_launcher/tree/homebrew_launcher_rpx/channel and edit graphics/meta/rpx files containing HBL specifincs things, so title IDs, names etc.)
OK so lemme get this straight: I can take those three HBL channel folders, leave the code and content folders alone, simply editing the files in the meta folder to match my app, then pack with NUSPacker and install the result with WUP Installer? That's how I read your post, but it doesn't really make sense to me that the code and content folders aren't really important :S
Also where does the RPX come into play? I don't see one in the HBL hierarchy that you linked to...
P.S. Many thanks for porting NX-Shell to WiiU-Shell! That's what I'm trying to install
I'd love to pick your brain about enabling USB support in it too, if/when you have the time
EDIT: Nevermind about the RPX question; just found it on my own USB with FTPiiU-Everywhere. For anyone else who's interested, it should go into the code folder
EDIT: OK I've had a go at downloading the HBL channel code/content/meta files, changing all values in all files that made sense to change, and packed it all with NUSPacker. Everything up to that point has gone smoothly as far as I can tell, but now WTF do I do with the NUSPacker output?!?!
I put it in a folder called "WiiUShell" in sd/install, and tried to run WUP Installer but it told me "no installable content found". I remember the folders having a weird, cryptic-looking name when I recently injected some old Wii games as VC titles, so does that have something to do with it? What is the "magic" name my install subfolder should have, and why isn't that part mentioned here?!?!
EDIT: OK I give up...just tried using
@TeconMoon's VC injector to create a similar package, copied the output folder name (which had the format "WUP-N-<4 letter title ID>_<Hex title ID>") and renamed my sd/install folder to that (updating the hex title ID part of course)...but to no avail! Still get "no installable content found" from WUP Installer. So I'm utterly and completely fucking lost
I've already wasted ~2 hours on this fucking bullshit, so screw it!
