openMX 0.10.3

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;
online, it meets every other native build of 0.10.3. (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 0.10.3

• Big worlds load far faster and use less memory. "Every game: one world" starts riding in about 4 seconds instead of 30, and needs about 1.9 GB instead of 2.7 GB; the other combined worlds load about four times faster. Far-off ground is drawn at lower detail and streams in as you ride, so a Steam Deck no longer runs out of memory on them
• Track and world pictures in the track pick are made once and kept, instead of being re-shot in the background (which could take a big world's worth of memory)
• Fog is now one slider, from the original's distance out to the whole map, showing how far you can see
• Settings with three or more choices open a dropdown list
• A Button Icons setting (Auto by default) picks which controller's button pictures the game shows
• The track pick has a Favourites filter in place of Wrecks, and the Worlds filter now lists MX Unleashed's own disc worlds
• Game Modifiers by machine: pick Bike, Biplane, Kiowa, Cars or World and see only that machine's settings; online, the cars' modifiers reach every player's cars
• A new Untamed handling choice rides the bike with MX vs. ATV Untamed's tuning, backflip and 360s
• Holding R1 with Cross or Square now does the plain trick when there's no R1 version of it, instead of nothing
• Driven cars bump into the riders' bikes in split screen and online, and a crashed rider's bike gets hit by planes flown into it
• Knocking props about makes their collision sounds, as in the original
• A reset (L1+R1 or a wreck's put-back) shows the rider at the new spot at once, camera and all
• The biplane camera keeps the plane in view through a climb or a loop
• The splash screen's button hint no longer floats above the bottom of the screen
