[Wii U] RetroArch on the Wii U does not install correctly

Description

When downloading RetroArch from the Homebrew App Launcher onto my Wii U, the install breaks and does not function at all.

Expected behavior

After installing, RetroArch is added to the Homebrew App Launcher as retroarch.elf. cores are stored in their own folder and can be installed and launched from RetroArch itself.

Actual behavior

In addition to retroarch.elf, all cores were added to the Homebrew App Launcher. Launching any of those cores causes the Homebrew App Launcher to return the error "not enough memory". Launching retroarch.elf results in a black screen lasting a few seconds, and then the program crashes back to the homebrew app launcher.

Steps to reproduce the bug

1. Get a Wii U with Homebrew App Store and Homebrew Launcher installed and at their newest versions.
2. In the Homebrew App Store, download Retroarch.
3. After the install has completed, exit the Homebrew App Store to the Homebrew Launcher.

Bisect Results

Seems to have happeded during the latest update to the Homebrew App Store (v 1.8.5, ULed 22/03/2020) but the problem could have been present in previous versions as I have not updated in a while.

Version/Commit

• RetroArch: Version 1.8.5 according to Homebrew App Store

Environment information

• OS: Wii U os, version 5.5.3 (latest US release)

Start by reproducing the installation through the Homebrew App Store and checking the resulting Homebrew Launcher contents, including retroarch.elf and the core files. Compare the observed package layout with the expected layout, then verify that retroarch.elf launches and that cores remain available from RetroArch without triggering the memory error.
