[juanvillacortac]

Native aarch64 GLES port for PortMaster handhelds; requires original game files.

Game Information

• New Port for: Star Wars Jedi Knight: Dark Forces II
• URL: https://github.com/juanvillacortac/OpenJKDF2 (handheld/aarch64 fork; upstream: https://github.com/shinyquagsire23/OpenJKDF2)

Submission Requirements

CFW Tests

Ensure your game has been tested on all major CFWs:

• ArkOS
• dArkOS
• AmberELEC
• ROCKNIX
• muOS
• Knulli
• Crossmix (Optional)

Resolution Tests

Test all major resolutions:

• 480x320 — 3:2 aspect ratio tested (Optional)
• 640x480 — internal render resolution
• 720x480 — 3:2 aspect ratio tested (rg34xx)
• 720x720 (RGB30) (Optional)
• Higher resolutions (e.g., 1280x720)

Notes

• Not RTR — user must own the game and copy JKDF2 assets to openjkdf2/jk1/ (GOG or Steam).
• aarch64 only — no armhf support.
• Native GLES 3 (no GL4ES); SDL2 from system, OpenAL bundled.
• Optional Mysteries of the Sith via openjkdf2/mots/ and in-game Expansions & Mods menu.
• Handheld QoL: D-pad movement, inventory on Activate, etc.

Game appears to be missing AmberELEC and ROCKNIX testing (according to your checklist)?

OpenJKDF2 port — release update

New build for Star Wars Jedi Knight: Dark Forces II. For now I'm hoping this is the last release in this round — I'm pretty happy with how it turned out. All that's left on my side is testing on ROCKNIX; on KNULLI (RG34XX SP, Mali-G31) it's running great.

Main takeaway: the game now runs very smoothly at full internal SSAA (1.0) — no need to downscale resolution on an H700.

Engine optimizations (GLES):
• Lite shader with 2 render targets when SSAO is off (less per-pixel work in the 3D world)
• Single-pass scene compositor (was two passes before)
• Lighter framebuffers (no position/normal G-buffer when SSAO is disabled)
• Mali fixes: correct GL symbol loading, VBO uploads without driver stalls, handheld viewport fix for menus/overlays
• Cached shader uniform locations (no per-frame glGetAttribLocation spam)

In practice: similar RAM usage (~400 MB), better FPS, clean pause menu, and SSAA 1.0 is playable on the RG34XX SP.
