This is a wrapper/port of the Android version of Half-Life 2 (v1.16.29 - 1.17.0025, nillerusr Source engine port).
It loads the original game's ARM64 libraries, and runs them as-is in a minimalist fake-Android environment.

You're going to need:

• the Source Engine .apk HERE and Half-Life 2 Files (from a legally obtained copy of the game)

To install, create /switch/hl2_nx/ on your SD card and lay it out like this:

/switch/hl2_nx/
  hl2_nx.nro
  lib/                  <- all 27 .so files from the APK's lib/arm64-v8a/
  lib/episodic/         <- EP1/EP2 libclient.so and libserver.so from the episodic APK
  assets/extras_dir.vpk <- from the APK's assets/
  files/                <- the fonts from the APK's assets/ (dejavusans.ttf,
                           dejavusans-bold.ttf, DroidSansFallback.ttf,
                           LiberationMono-Regular.ttf, Itim-Regular.otf)
  hl2/                  <- from the game data (the big one: hl2_pak, textures, sounds, maps...)
  episodic/             <- episode 1 (Optional)
  ep2/                  <- episode 2 (Optional)
  platform/             <- from the game data

Episode One / Two need episodic libclient.so and libserver.so in lib/episodic/ from HERE.

This will not work in applet/album mode — use a game override (hold R on a title) or a forwarder. The Switch needs the full application memory pool

A config.txt is created next to the nro on first run:

• screen_width / screen_height — passed as -w/-h when both set; -1 lets the engine pick
• gamedir — game to launch: hl2 (default), episodic (Episode One), or ep2 (Episode Two)
• args — extra Source command line
• lang — Source language name (default english)

You need devkitA64 plus the following pacman packages:

• switch-sdl2
• switch-sdl2_image
• switch-mesa
• switch-libdrm_nouveau
• switch-zlib
• switch-ffmpeg

• nillerusr for the Android Source engine port this wraps
• TheOfficialFloW & fgsfds for the so-loader lineage
• Masagrator for the hl2_picker
