Games which are known to be buildable and playable on POWER9 Raptor systems, potentially with necessary tweaks needed in order to run.

Title Compatibility Hardware Tested Software Tested Notes
Minecraft Java Edition - Minecraft ★★★★ Blackbird C1P9S01? Void Linux Cannot use the native game launcher, text to speech as they are built for x86. multimc from repos, openjdk 8 or 11, default 4kB page kernel, getting >60fps easily regardless of the resolution (rx 5700 xt), works out of box. https://forums.raptorcs.com/index.php/topic,118.0.html

Xonotic ★★★ Blackbird C1P9S01 Debian 10.6 Infrequently locks up the desktop session requiring a hard reset. I have yet to determine the cause.
Veloren Blackbird C1P9S01 Debian 10.6 Fails to build on nightly rustc due to packed_simd. (error[E0635]: unknown feature mmx_target_feature) Awaiting packed_simd_2 with the 0.3.4 Veloren release. Veloren 0.3.4 is released, so it might be productive to test again.

Vega Strike ★★★★ Blackbird C1P9S01 Debian 11.3 Edit ~/engine/src/gfx/background.cpp, prepend signed (around line 238) so that it is signed char tcoord[4][4];. Vega Strike should then build and run successfully.

DeSmuME - Nintendo DS Emulator ★★★★★ Blackbird C1P9S01 Debian 11.3 Works without issues.
Dolphin - GameCube/Wii Emulator Blackbird C1P9S01 Fedora 32 (rawhide) Because of lacking JIT, the performance is dreadful. Dolphin's Cached Interpreter mode is a lot faster since these tests were run, so trying again with Dolphin 2409 or higher might be productive. It also might be productive to test with a game that's known to run at full speed in Cached Interpreter mode on x86_64, such as Cave Story.
ECWolf - Wolfenstein 3D ★★★★★ Blackbird C1P9S01 Fedora 32 (rawhide) A couple glitches but generally works fine (icculus version) https://forums.raptorcs.com/index.php/topic,98.msg871.html#msg871

ET: Legacy - Wolfenstein: Enemy Territory ★★★★ Blackbird C1P9S01 Fedora 32 (rawhide) The game plays perfectly. The only downside is lacking support for any game hosted with x86_64 server. https://forums.raptorcs.com/index.php/topic,266.msg2023.html#msg2023
SuperTux ★★★★★ Blackbird C1P9S01 Debian 11.3 Works without issues.
SuperTuxKart ★★★★★ Blackbird C1P9S01 Debian 11.3 Works without issues.
OpenSpades - Ace of Spades Blackbird C1P9S01 Debian 11.3 Fails to build due to AngelScript dependency.

Naikari ★★★★★ Blackbird C1P9S01 Debian 11.3 Works without issues. Ignore the python3-pip dependency and just install meson directly from your package repo to avoiding polluting your system with python pip packages.
SpaceCadetPinball - Full Tilt! Pinball ★★★★★ Talos II (T2D9P01?) Fedora 34 https://www.talospace.com/2021/10/tonights-game-on-openpower-space-cadet.html
Shockolate - System Shock ★★★★★ Talos II (T2D9P01?) Fedora 34 Does not support higher resolution game assets. https://www.talospace.com/2021/08/tonights-game-on-openpower-system-shock.html

DOSBox - MS-DOS Emulator ★★★★★ Talos II (T2D9P01?) Fedora 31 https://www.talospace.com/2020/01/dosbox-jit-on-ppc64le-and-how-you-can.html
Extreme Tux Racer ★★★★★ Blackbird C1P9S01 Debian 11.3 Works without issues.
Sonic Robo Blast 2 ★★★★★ Blackbird C1P9S01 Debian 11.3 Works without issues. Assets need to be extracted from the installer from other releases, copy into ~/SRB2/assets/installer/)
GearHead 1: Arena ★★★★ Blackbird C1P9S01 Debian 11.3 Tile sprites have vertical artifacting, affecting some text as well. Similar artifacting found in ffmpeg issue 8802.
mGBA - Game Boy Advance Emulator ★★★★★ Blackbird C1P9S01 Debian 11.3 Works without issues.
Cube 2: Sauerbraten ★★★★★ Blackbird C1P9S01 Debian 11.3 Works without issues.
Falcon-mkxp - RPG Maker XP / VX / VX Ace ★★★★ Talos II (T2D9P01?) Debian 11.5 Apply PR #5 and PR #6; build instructions will then work out of the box. Briefly went in-game without issues (audio works fine) in Coming of Age v2.2.1 and Saori's Ecchi Adventure v1.06 (the latter required copying win32_wrap.rb from the former, and downloading+extracting the RTP via InnoExtract). FPS counter shows well over 200fps on AST2500, but this may be inflated due to an FPS counter bug (seems more like 20fps in practice).
OpenJK - Star Wars: Jedi Knight - Jedi Academy ★★★★★ Talos II (T2D9P01?) Gentoo Works without issues. Gets 25fps at 800x600 with LLVMpipe (patched to use 64 threads).
OpenTyrian - Open-source port of the DOS shoot-em-up Tyrian ★★★★★ Blackbird C1P9S01 Void Linux Compiles on void linux without issues. Runs perfectly even on highest scaling.
LinApple - Apple IIe Emulator forked from applewin ★★★★★ Blackbird C1P9S01 Void Linux Compiles and runs on void linux without issues.
NBlood - Blood ★★★★★ Talos II Gentoo Works fine.
EDuke32 - Duke Nukem 3D ★★★★★ Talos II Gentoo Works fine.
GZDoom - Doom I && II, Heretic, Hexen, Strife, Chex Quest ★★★★★ Talos II Gentoo Works fine.
Shadow Warrior ★★★★ Blackbird ? https://www.talospace.com/2023/01/tonights-game-on-openpower-shadow.html
ZGloom - Gloom ★★★★★ Talos II Fedora 36 https://www.talospace.com/2022/09/tonights-game-on-openpower-zgloom.html
Rigel Engine - Duke Nukem II ★★★★★ ? Fedora 36 https://www.talospace.com/2022/07/tonights-game-on-openpower-duke-nukem-ii.html
dRally - Death Rally ★★★★★ Talos II Fedora 35 https://www.talospace.com/2022/04/tonights-game-on-openpower-death-rally.html
mkxp-z - RPG Maker XP / VX / VX Ace ★★★★★ Talos II Fedora 38 Builds from source for ppc64le without issues; does not build from source for ppc64 BE. Official binaries available for ppc64le. YJIT not available on POWER due to limitations of upstream Ruby (but I'd be surprised if many games need it). Briefly went in-game (didn't test audio) in Saori's Ecchi Adventure v1.06 on ppc64le. On AST2500 with Lanczos scaling to 1200p, gets ~23fps (on Plasma X11) or ~55-85fps (on Plasma Wayland). Uses SDL_image (with vendored libjxl), and is subject to the JXL POWER SIMD performance issues thereof.
Ren'Py ★★★★★ Talos II Debian 12.0 Builds from source without issues (didn't try Debian's package, but probably it works fine too). Played through the full intro and first event of Harem Hotel v0.15.1 without any issues (didn't test audio) on ppc64le (didn't test ppc64 BE).
FTL: Advanced Edition ★★★★ Talos II Gentoo Works fine on ppc64le with box64. The game loads quite slowly (a couple of minutes), but once loaded, is playable (albeit still slow).
