Game Information

• New Port for: Olduvai (a native engine recreation of Prehistorik, 1991; the player supplies the game files)
• URL: https://github.com/ksokolowski/olduvai
• Testing Thread URL: https://discord.com/channels/1122861252088172575/1563980715471929570

Authorship & Testing

• I wrote and understand this script/patch myself, or clearly marked which parts came from an AI assistant and reviewed them
• I can explain every non-standard line in my launch script

AI assistance, plainly: the launcher and the packaging scripts were written with
Claude (an AI assistant); I reviewed them and tested them on my own devices. The
engine is my project.

CFW Tests

Ensure your game has been tested on all major CFWs:

• AmberELEC (testing thread)
• dArkOS: tested on ArkOS4Clone, the ArkOS fork on my R36S (RK3326, 640x480)
• muOS (testing thread)
• Knulli (TrimUI Smart Pro, 1280x720)
• ROCKNIX
  -> [x] Libmali (testing thread)
  -> [x] Panfrost (testing thread)
  -> [x] Adreno (Optional) (testing thread)
• Other (add here)
  • ROCKNIX community build on the Powkiddy A12 and A13 (RK3128, Mesa lima on the Mali-400; 1024x600, armhf)

The community results are in the testing thread linked above.

Resolution Tests

Test all major resolutions:

• 480x320 (Optional)
• 640x480 (R36S, and the testing thread)
• 720x720 (Optional) (testing thread)
• Higher resolutions (e.g., 1280x720): 1024x600 (A12, A13), 1280x720 (TrimUI Smart Pro)

File Structure

As the template: port.json, README.md, screenshot.png, cover.png,
gameinfo.xml, Olduvai.sh, and olduvai/ with the two binaries
(olduvai.aarch64, olduvai.armhf), olduvai.gptk, fonts/ (OFL, for the HD
text), licenses/, and three empty folders for the player's files (game/,
mt32-roms/, soundfonts/, each with a PUT-FILES-HERE.txt).
build_release.py --do-check is clean for the port.

Script Conventions

The launcher follows Powermanga's. The lines beyond it, and why:

• XDG_CONFIG_HOME="$GAMEDIR/conf", OLDUVAI_BUG_DIR: settings, saves and
  bug reports stay inside the port folder.
• OLDUVAI_PANEL="${DISPLAY_WIDTH}x${DISPLAY_HEIGHT}": the engine fits its
  render scale and aspect to the panel PortMaster reports.
• The PROFILE choice: panels under 400 lines start in the Classic (DOS) mode,
  taller ones in Enhanced; the player can switch in Options - Style.
• The SoundFont loop: if the player added a .sf2 / .sf3, it plays the
  General MIDI music (the synthesizer is compiled in).
• chmod +x on the binary at run time: the exec bit does not survive every
  way the package reaches a device.

Binaries and the C++ runtime

The 0.9.11 release (build a69e920), built from the public repository with
zig's clang for aarch64-linux-gnu and arm-linux-gnueabihf, glibc floor
2.17. From the device each binary loads only libSDL2-2.0.so.0, libc,
libm, libpthread and libdl; nothing is bundled in libs.<arch>/.

The C++ runtime is LLVM's libc++, linked in statically. I know AGENTS.md
warns against static libstdc++, and I read that as being about a second
copy of GCC's runtime colliding with the system one that a C++ GPU driver
(the libmali blobs) loads into the same process. libc++ keeps its symbols
in its own std::__1 namespace, so it does not collide with the system
libstdc++, and no C++ exception crosses into SDL or the driver. It also
keeps the binaries free of any GLIBCXX version requirement. If you would
still rather have the usual build against the device's libstdc++, say so
and I will provide one.

The armhf binary assumes no hardware divide, so it runs on Cortex-A8 / A9
cores too.

Hi @ksokolowski

I don't see the testing matrix in the Olduvai testing thread on our discord server

Can you please add in the OP (I'll ask in discord as well just icymi :D):

CFW Tests:
[] AmberELEC
[ ] dArkOS
[ ] MuOS
ROCKNIX
-> [ ] Libmali
-> [ ] Panfrost
-> [ ] Adreno (Optional)
[ ] Knulli

Resolutions:
[ ] 480x320 (Optional)
[] 640x480
[ ] 720x720 (RGB30) (Optional)
[ ] Higher resolutions (e.g., 1280)

We need it fulfilled before we can review the PR :)

Hi @ksokolowski

I don't see the testing matrix in the Olduvai testing thread on our discord server

I have copied this testing matrix to post on Discord. If there are some edits needed there still please let me know - and naturally if any Discord admin can help that would be also great. This is my first contribution to PortMaster :)

No problem, there is always a first time. Thank you for coming to PR your own game/engine, that's not often we see this ;)

[cdeletre]

I only have minor CR, overall it's very well packed for a first port ;)

[cdeletre]

Can you please replace with this optimized png (smaller file size).

You can also optimize by yourself with https://jantrueno.github.io/PortMaster-Wiki/tools/png-compressor/ if you prefer.

It's missing few entries:

Duplicated, must be removed :)

[ksokolowski]

Thanks for the review, @cdeletre! All three are done in 05ca3e5:

• cover.png optimized (380 KB down to 130 KB)
• store and availability added to port.json
• duplicate olduvai/screenshot.png removed

build_release.py --do-check shows no errors for the port. Ready for another look when you have time.
