A FAN-MADE mod called AstroQuest now RUNS Astro Bot Rescue Mission, the 2018 PlayStation VR exclusive, on a Meta QUEST 3, either STANDALONE on the headset or streamed from a Windows PC. The project went public on GitHub, where its developer, Bigmak94, posted versions 0.11 through 0.13 on October 3. It is FREE and open source, but it is also NARROW: it supports exactly ONE regional build of the game, and you have to DUMP it yourself.
Road to VR reported on October 5 that Bigmak94, who previously BUILT a Super Mario Galaxy VR mod, said in a Reddit post that the AI agent Claude did the HEAVY work of MODIFYING shadPS4, an open-source PlayStation 4 emulator. Road to VR called it the latest example of AI-assisted coding driving an EXPLOSION in VR modding.
What the mod actually adds
According to the AstroQuest README, the emulator is shadPS4 on the PC and an ARM64 fork of it on the headset. The project adds what the game EXPECTS from a PlayStation VR: headset TRACKING and reprojection, the PlayStation Camera’s view of the controller (rebuilt from the Quest’s HAND TRACKING around the gamepad), the 3D SOUND engine, the MICROPHONE the game uses for blowing at objects, and fixes for timing and resolution under emulation.
Control still runs through a GAMEPAD. The README asks for a PS5 DualSense, which stands in for the PS4 controller with its buttons, sticks, touchpad, motion sensors, rumble and light bar. A DualShock 4 may work but is UNTESTED. On the PC path, the Quest’s own Touch controllers can stand in.
The performance gap is real
The developer’s own comparison table is CANDID about what a MOBILE chip can do:
- PS4 + PS VR: 60 frames per second, 960×1080 to 1440×1536 per eye.
- Quest 3 standalone: 30 fps in levels and 45 in lighter scenes, 816×870 to 1440×1536 per eye.
- PC via Virtual Desktop: 60 fps, 1440×1536 up to 3600×3840 per eye.
The README says the standalone build is “fully FUNCTIONAL and playable” but that the Quest 3’s GPU is “pushed to its limits,” so visuals run at LOWER resolution and fidelity than the original console. For the PC route, it lists Windows 10 or 11, a Vulkan 1.3 graphics card, at LEAST 16 GB of memory (the emulator requests about 14 GB), and Virtual Desktop with its VDXR runtime.
The fine print matters MORE than the demo
The project ships NO game files. Players need the European release, CUSA12392, version 1.00, dumped from their OWN PlayStation 4, as either the game folder (about 13 GB) or a package made from that dump. The README is explicit that a package downloaded from the PlayStation Store is ENCRYPTED and cannot be used, and that the timing and resolution fixes apply ONLY to that one version. Other regions are UNTESTED. The Quest 3S shares the Quest 3’s chip but, per the README, NOBODY has tried it.
Installing means putting the headset in DEVELOPER MODE and sideloading an APK with adb or SideQuest. The developer also describes the project as a WORK IN PROGRESS, built and tested by ONE person on one Quest 3 and one PC, with Worlds 1 and 2 played through on the standalone build.
AstroQuest is licensed under GPL-2.0-or-later, the same license as shadPS4, and states that it is not affiliated with or endorsed by Sony Interactive Entertainment. Sony has NOT commented publicly on the mod as of publication.
Why it matters
The mod lands in a BUSY stretch for headset-hopping hacks. Metaverse Watcher has tracked a Titanfall 2 VR mod and work bringing PS VR2 Sense controllers to Steam Frame in the past WEEK alone. The PATTERN is consistent: platform-locked VR software is getting PORTED by small teams, sometimes a SINGLE person, with AI coding tools in the loop.
For players, the honest read is that AstroQuest is a PROOF that first-generation PSVR games can RUN on Meta hardware, not a POLISHED replacement for the original. For platform holders, it is another sign that EXCLUSIVITY in VR is getting HARDER to enforce once the original hardware AGES out.
