Switch to the openvr/oculus/openxr branch. And add -openvr to the launch options. The game runs pretty well with it and without any 3D issues like some older oculus games.

Most of those original “under 50MB verified” files are now gone—hosts deleted them, links expired. But the technique lives on in tools like PS2压缩工具 (PS2 Compactor) and ESR Patcher. Today, a responsible gamer can compress their own legally-owned PS2 discs to 200–400MB without losing essential gameplay.
The 50MB promise was never about quality. It was about possibility. It proved that even a bloated, DVD-era console could be squeezed into a dial-up download—if you were willing to sacrifice everything but the soul of the game.
And for a kid with a 512MB USB stick and a library computer, that soul was enough.
Finding PlayStation 2 games that fit under 50MB is rare, as most full PS2 titles were originally distributed on DVDs holding up to 4.7 GB. However, certain early CD-based games, simple arcade ports, and "highly compressed" (ripped) versions can meet this ultra-low size requirement. Verified PS2 Games Under 50MB
While many lists claim "high compression," these specific titles are naturally small or have verified rips that fit the 50MB limit: Prince of Persia Classic: Approximately 4MB. Chess Challenger: Extremely small at roughly 8MB.
Metropolismania 2: A city-building sim verified around 12MB. Billiard Exciting: A sports title coming in at 20MB. Casper Scare School: Verified at 23MB.
Space Invaders Anniversary: A collection of classics at 26MB. Downhill Slalom: A skiing game at 32MB. 21 Card Game: Simple card game at 33MB. Snooker Championship: Verified at 32MB. Monster Truck Arena Edition: A racing title around 35MB. Offroad Extreme: Verified at 36MB. Billiard Coolshot: Verified at 37MB.
Harvest Moon: Save the Homeland: A full RPG experience remarkably small at 37MB. Hot Wheels Beat That: Verified at 40MB. GT-R Touring: A racing sim at 41MB. Power Volleyball: Verified at 42MB. Home Alone: Verified at 43MB. Captain Scarlet: Verified at 45MB. Moto X Maniac: Verified at 46MB. Ocean Commander: Verified at 48MB. 10 Pin Champions Alley: Verified at 50MB. How to Achieve Ultra-Compression
If you have larger ISO files, you can use specialized tools to shrink them for use with emulators like PCSX2 or AetherSX2:
GZIP Compression: PCSX2 supports .gz files. You can use 7-Zip to compress an ISO into GZIP format at the "Ultra" level to save significant space without losing performance.
CHD Conversion: This is the gold standard for emulation. Converting .iso to .chd (Compressed Hunk of Data) provides lossless compression that can reduce file sizes by up to 40-90%.
CSO Format: Primarily used for PSP, some PS2 loaders also support .cso (Compressed ISO) to reclaim storage. Pro-Tip: "Ripped" vs. "Compressed"
Compressed: Uses algorithms (like CHD or GZIP) to shrink the file. It is lossless—the game remains exactly as intended.
Ripped: Developers or "rippers" manually remove "junk" data, like high-quality FMV cutscenes or extra languages, to force a game under a certain size (e.g., 50MB). These versions are lossy and may crash or lack music/videos.
In the context of file sharing and ROM preservation, "verified" typically refers to a ROM that matches the Redump database (a preservation project ensuring 1:1 accuracy with original discs). A Redump PS2 ISO is never under 50MB.
What are these sub-50MB files actually?
This report addresses the user request for "verified" PlayStation 2 (PS2) games highly compressed to under 50MB.
The finding is negative. Based on technical architecture and data compression standards, it is statistically impossible for a standard, playable PS2 game to be compressed to under 50MB. While "ripped" versions (versions with music/videos removed) exist in the range of 200MB–500MB, a sub-50MB file claiming to be a full PS2 game is almost certainly fake, malicious, or a "demo" file masquerading as a full game.
A: None that are verified. The smallest open-world game is Simpsons: Hit & Run after a "dummy remover" (approx 380MB). Anything claiming lower is a virus.
Open with 7-Zip
Test in PCSX2 emulator
Scan with VirusTotal
VR itself is working fine with Euro Truck Simulator 2 using the Oculus branch. Other issues are the common issues related to the game itself, that's mostly VR performance is pretty bad if you are using big maps like Promods, and you will have to live the lower FPS and resolution
Need to opt-in to a beta and force the use of Proton to start the game in VR mode, but works without issues.
