Gets to menu, crashes if starting new game/loading game. Game plays sound for keyboard input but doesn't add characters on text input fields.

Only Win32 on Steam, retail disc has Linux installer, mac was separate SKU. Mac and Linux builds used SDL 1.2, Windows didn't use SDL at all.

There's an SDL2 patch out there somewhere, but mainline is still 1.2. Good test case if nothing else.

Game is closed source, engine is open: http://www.icculus.org/hge-unix/ (SDL only on Linux/Mac).

Game uses ManyMouse (https://icculus.org/ManyMouse) for input, and is probably hardcoded to XInput2, so Wayland is going to be an issue.

This _was_ SDL 1.2 at one point, but the Steam version is now on SDL 2.0. Not sure if any older versions using 1.2 are still distributed via other platforms.

I thnk there's an SDL2 patch out there? But it originally shipped as 1.2, and the game was GPL'd.

Open source! Newer builds might be SDL2, but it was 1.2 for a loooooong time

Everything seems to be working except keyboard input on the sign-in screen. Keyboard input seems to work fine during gameplay.

Likely won't even start on modern machines without effort, before getting to SDL itself.

This has been updated for SDL2 since going open source, but the Linux original was 1.2

"prboom was one I hit (original not later forks) and use of 1.2 actively broke stuff til I hacked some env vars."

Unfortunately only the remastered version is sold on Steam - the Linux version sold in an old Humble Indie Bundle used SDL 1.2. I'm not sure what the remastered version uses.

YUV overlays currently unimplemented, so the test apps fail. sdltheoraplay --opengl works, because it doesn't use a YUV overlay at all.

Original FTP site host was taken down. Lutris has a mirror for the necessary client files

They have nightly builds and AppImg installer; Steam build can be installed via: https://github.com/dreamer/luxtorpeda

Not sure about nightly builds, but Fedora build for version 1.9.2 depends on SDL1.2

Lutris build: https://lutris.net/games/aliens-versus-predator-classic-2000/ ; preparation for Luxtorpeda/Steam build: https://github.com/dreamer/avp-forever

Open source port of Arx Fatalis. Supports SDL2, but portable binaries (http://wiki.arx-libertatis.org/Download#Portable_Binaries) use SDL 1.2. Needs the original data files, available on GOG and Steam. Initial testing looks good.

When moving the mouse in the main menu for the first time, the red trail always starts at the upper left corner. Maybe related to https://bugzilla.libsdl.org/show_bug.cgi?id=1612 ?
