openMX 0.10.0

openMX is MX Unleashed (PS2, 2004) rewritten from scratch: the original's physics, tricks and timing, proved
tick for tick, on today's screens at any resolution, with split screen, online play and mods.

Download

Platform	File	How to play
Windows 10/11	openmx-windows-x86_64.zip	Unzip, then drop your ISO on openmx.exe once; start openmx.exe after
Linux / Steam Deck	openmx-linux-x86_64.tar.gz	Unpack, run ./openmx your.iso (or drop the ISO on it) once; ./openmx after. For Steam (with artwork): run add-to-steam.sh
iPhone / iPad (iOS 15+)	add the source in one tap	Easiest: add the source in one tap (Feather, AltStore, SideStore), or add https://fizl0.github.io/apps/source.json under Sources by hand; install openMX from it and updates arrive there. Then put your ISO in Files → On My iPhone → openMX. Touch controls or a controller. Signing it yourself instead: openmx-ios.ipa (unsigned; Sideloadly, AltStore…)
Browser	openmx.dev	Nothing to install

Every download above runs the native sim: the original's physics on your machine's plain floats, faster
than the PS2's arithmetic and not bit-for-bit with it. The menu's corner and --version say "native sim";
online, it meets every other native build of 0.10.0. (The exact, PS2-arithmetic build is tools/build.sh --exact-sim.)

What you need

Your own disc image of MX Unleashed (USA, SLUS-20767). No game data is included, and the game reads
your ISO on your own machine: nothing is uploaded.

New in 0.10.0

• The native sim. Every download now runs the original's physics on your machine's plain floats instead of copying the PS2's arithmetic: about twice as fast, so split screen on a Steam Deck holds 60 fps. It is no longer bit-for-bit with the original (rides feel the same, but can part by a hair over time). Online games meet only other native builds of the same version, not 0.9.x. A recorded tape now names its sim; tapes from older versions still play, but may drift from what was recorded. The menu's corner and --version say "native sim"
• The splash shows a New version notice with its Update, Download or Refresh button, and the build's version (or commit) small in its corner; the website's header shows it too
• The Kiowa helicopter: park it, switch into it, fly it and wreck it, with its engine, rotor wash and wreck sounds
• The rider is drawn from the riding ragdoll, with the original's give in the body
• Knockable props (free06's eyeballs, free09's balls) are knocked by a fallen rider, by the biplane and by each other; the biplanes in split screen and online hit each other
• Trucks you hit move as physical bodies, and a bike can ride on top of them
• Flips score as the original's again (the flip-at-the-start scoring is gone)
• Worlds can be downloaded from the mod store, on the desktop and in the browser, which now sees every mod the store installed; an MX World load can be cancelled
• The Garage's bike, paint and class pickers answer at once, one step per press
• MX vs. ATV handling works online: the room carries the Handling setting
• Under World Sky Global each map keeps its own sunlight
• Automatic render scale judges by the graphics card's own time, so it no longer drops and stays low
• Browser: pads the browser does not map keep their d-pad and triggers
