Marathon Trilogy (Aleph One)
Aleph-One-Marathon/alephone
Aleph One: an open-source continuation of the Marathon 2 and Marathon Infinity engine, born from the Marathon 2 source code Bungie released under the GPL in 2000; Bungie released Marathon Infinity’s source as well in 2011. It plays all three Marathon games, originally released for the Mac, and dozens of community scenarios, from new levels to total conversions, picked with a scenario chooser. There are builds for Windows, macOS, and Linux (as a Flatpak), and the three games are on Steam as Classic Marathon, Classic Marathon 2, and Classic Marathon Infinity, with achievements and Steam Workshop. It can run at 30 fps like the original or with interpolation at 60 or 120 fps or uncapped, and it adds 3D audio with HRTF, Lua scripting, game recording with video export, and multiplayer and co-op for up to eight players over LAN or the internet, with a lobby to find games, dedicated servers so no router setup is needed, and monthly leaderboards with an optional lhowon.org account. The latest release, 1.11.1 (September 30), fixes bugs and security issues. Each game’s download includes its data, which Bungie allowed to be distributed for free in 2005 and which the project distributes under a limited license Bungie granted it in 2021.
You needNo copy needed: Bungie has allowed the three games to be distributed for free since 2005, and each of the project’s downloads already includes the game data, which can also be downloaded separately from its website. Plus Windows, macOS, or Linux.
Bugdom
jorio/Bugdom
Bugdom, Pangea Software’s 1999 Mac game, updated for Windows, macOS, and Linux by Iliyas Jorio with Pangea’s approval, after Pangea offered to let them port it once their Nanosaur port was done. The original used QuickDraw 3D, which never went past Mac OS 9, so until this port, playing it required a PowerPC Mac running OS 9. Version 1.3.0 (December 29, 2020) made it work on modern systems at any resolution beyond the original 640×480, with widescreen touch-ups and built-in save and settings dialogs, and 1.3.1 replaced the QuickDraw 3D code, which had been running on Quesa, with a renderer made for the game. Later releases added smoother movement at high frame rates, controller-driven menus, an option to constrain the picture to 4:3, Retina and Apple silicon on the Mac, and ARM64 Linux; the latest, 1.3.4 (January 3, 2024), fixed gameplay differences that showed up above 100 fps. Since then the code has moved to SDL 3, not yet in a release. It fixes gameplay bugs but aims to stay faithful to the original, with no changes to its design. The downloads, free or pay-what-you-want on itch.io, include the whole game, which the author publishes under the CC BY-NC-SA 4.0 license with permission from Pangea Software.

Nanosaur
jorio/Nanosaur
A port of the Nanosaur source code that Pangea Software released in 1999, updated for macOS, Windows, and Linux with Pangea’s permission. To carry it over, the author wrote Pomme, a partial reimplementation of the Macintosh Toolbox API; the first release rendered with a fork of Quesa (an implementation of QuickDraw 3D) and since 1.4.2 it has its own renderer. It adds arbitrary resolutions and fixes gameplay bugs without changing the game’s design. Unlike almost every project in the catalog, the repository includes the Data folder with the game’s audio, models, images, and movies, released by its owner. The code is licensed CC NC-BY-SA 4.0. The latest version is 1.4.4 (February 5, 2023), with packages for macOS, Windows, and Linux (x86-64 and ARM64 AppImages).
You needNo copy of the game is needed: the data comes with the port, released by Pangea Software. Just macOS, Windows, or Linux.
Mighty Mike
jorio/MightyMike
Mighty Mike, Pangea Software’s top-down action game set in a toy store, updated for Windows, macOS, and Linux by Iliyas Jorio. It came out for the Mac in 1995 as Power Pete and was re-released as Mighty Mike in 2000. It aims to stay as faithful as possible to the original in gameplay and graphics, with a few enhancements: a widescreen mode, an uncapped frame rate with movement interpolation, and twin-stick controller support. Version 3.0.0 (April 12, 2021) made it work on modern systems; 3.0.1 added an option that remaps colors from the Apple RGB profile the game was made for to sRGB, and a maximum windowed zoom setting; and 3.0.2 (January 28, 2023) added its own OpenGL-based renderer and builds for ARM64 Linux and for Mac OS X Tiger on PowerPC, with a Windows-only hotfix on February 5. Since then the code has moved to SDL 3, not yet in a release, and the next version will require macOS 10.13. The downloads, free or pay-what-you-want on itch.io, include the whole game, which the author publishes under the CC BY-NC-SA 4.0 license with permission from Pangea Software.

Otto Matic
jorio/OttoMatic
Otto Matic, Pangea Software’s 2001 Mac game, updated for Windows, macOS, and Linux by Iliyas Jorio with Pangea’s permission. It came out as a Carbon app for Mac OS 9 and Mac OS X, shipped bundled with some Macs of the time, and was later ported to 32-bit Intel Macs, but it stopped working when macOS 10.15 dropped 32-bit apps and, with them, Carbon; Pangea’s last official release was 3.0.9, from February 2008. Version 4.0.0 (August 21, 2021) brought it to modern systems with the UI and scenes reworked for widescreen, modern controller support, new menus, and many gameplay and cosmetic fixes. 4.0.1 (January 31, 2023), the latest release, stabilized the physics for high frame rates, raising the non-vsync cap from 100 to 500 fps, and added seamless terrain texturing, smoother motion, settings to center and scale the infobar and to turn off automatic camera alignment behind Otto, Retina on the Mac, an ARM64 Linux build, fairer saucer abductions so every human can be rescued, and fixes for softlocks and level-specific bugs. Since then the code has moved to SDL 3, not yet in a release. It aims to stay faithful to the original, with slight updates to presentation and handling. The downloads are free and include the whole game, which the author publishes under the CC BY-NC-SA 4.0 license with permission from Pangea Software; on itch.io you can pay what you want.

Cro-Mag Rally
jorio/CroMagRally
Cro-Mag Rally, Pangea Software’s 2000 racing game for the Mac, updated for Windows, macOS, and Linux by Iliyas Jorio with Pangea’s permission. It’s a port of the original Mac OS 9 version that aims to be the best way to play it today: it fixes bugs that got in the way and adds a few new features in the spirit of the original, such as split screen for up to four players on one computer (the original topped out at two), a subtly animated interface tweaked for widescreen displays, an optional race timer with a scoreboard, the option to change the character’s outfit on the selection screen, a proportional font with the accented characters of every language in the game, and a restyled physics editor. The OS 9 version’s NetSprockets network multiplayer is missing. 3.0.0 (June 27, 2022) was the port’s first release, and the latest, 3.0.1 (February 7, 2024), brought rebindable left stick and D-pad controls, Retina and macOS Sonoma Game Mode support on the Mac, Wayland on Linux, and better Italian and Spanish translations. Since then the code has moved to SDL 3, not yet in a release. The downloads, free or pay-what-you-want on itch.io, include the whole game, which the author publishes under the CC BY-NC-SA 4.0 license with permission from Pangea Software.

Nanosaur II: Hatchling
jorio/Nanosaur2
Nanosaur II: Hatchling, Pangea Software’s 2004 Mac game, updated for Windows, macOS, and Linux by Iliyas Jorio with Pangea’s permission. It continues the first Nanosaur’s story, but this time you fly a pterodactyl loaded with weapons: there’s a three-level adventure mode where you shoot down enemy dinosaurs and rescue eggs, and six two-player levels with racing, capture the flag, and battle. It’s a port of the original Mac version; compared with Pangea’s last release, 2.0.7 from 2008, it improves widescreen, mouse, and controller support, makes terrain texturing seamless, adds optional story subtitles, revamps the menus, lets you scale the status bar, fixes minor gameplay bugs, and shows the story slides in high resolution. The only release is 2.1.0 (December 17, 2022); since then the code has moved to SDL 3, fixed animation hiccups at high frame rates, and gained a Russian translation, not yet in a release. The downloads, on GitHub and, free or pay-what-you-want, on itch.io, include the whole game, which the author publishes under the CC BY-NC-SA 4.0 license with permission from Pangea Software.

⑂ Fork of softdorothy/GliderPRO
Glider PRO (Aerofoil)
elasota/Aerofoil
Aerofoil: a port of Glider PRO, John Calhoun’s classic paper airplane game for the Macintosh (1994), from the source code the author released under the GPL-2.0. It offers a 90s-style interface, gamepad support, high-quality upscaling with color correction, a full port of the level editor, import tools that unpack and convert most community content, and a new touchscreen interface for mobile devices. The game’s data (the application and the houses, meaning the levels, by Calhoun, Kim Money, Jonathan Chin, Ward Hartenstein, Shawn Brenneman, Steve Sullivan, and others) is published alongside the code, so the repository includes it (about 49 MB) and the downloads already bring it. The Windows releases go up to 1.1.2 (November 10, 2021); the macOS one is 1.1.0 (May 14, 2021). There’s also a browser (HTML5) version on itch.io. The Android version has been discontinued because of its maintenance demands, and its Google Play listing was retired in August 2025. The last commit is from September 6, 2026.
You needNo copy needed: the author published the game with its code and the data comes with the downloads. Plus Windows or macOS (or a browser, with the itch.io version).
Bugdom 2
jorio/Bugdom2
Bugdom 2, Pangea Software’s 2002 Mac game (the sequel to Bugdom), updated for current systems by Iliyas Jorio with Pangea Software’s permission. Version 4.0.0 (October 8, 2023), its only release, brings cross-platform support for macOS, Windows, and Linux (x86-64 and ARM64), widescreen, better mouse and controller support, seamless terrain texturing, and minor gameplay fixes. The repository includes the original instruction manual in eight languages and a list of cheat codes, and its last commit is from February 2025. The code and data are published under the CC BY-NC-SA 4.0 license with permission from Pangea Software, and the downloads are free, with an optional pay-what-you-want donation on itch.io.

Billy Frontier
jorio/BillyFrontier
Billy Frontier, the “cowboys in space” game Pangea Software released in 2003 for PowerPC Macs, updated for macOS, Windows, and Linux by Iliyas Jorio with Pangea’s permission. It’s an arcade-style action game with duels, shootouts, and stampedes. In shootouts you turn by slamming the cursor to the screen edges, with the mouse wheel, with horizontal trackpad scrolling, or with the keys. The latest version, 1.1.1 (September 6, 2023), smoothed that turning, added settings for wheel speed and direction, fixed graphical artifacts in smoke and flames, fixed right-edge turning on Retina Macs, and updated SDL to 2.28.3; there are downloads for Linux x86-64 and ARM64, macOS, and Windows. The downloads include the whole game, which the author publishes under the CC BY-NC-SA 4.0 license with permission from Pangea Software.

Ares (Antares Windows edition)
Hardpartying4u/Antares-Windows
An unofficial Windows fork of Antares, the open-source port of Ares by Nathan Lamont (Bigger Planet), with its own changes: a native MSVC build, integer interface scaling, rebindable controls with presets (classic, modern with mouse, and modern with WASD), box selection, right-click orders, control groups with a bar, wheel zoom, XInput and DirectInput gamepads, and an Arena mode with four battles. It removes network play and the demo from the menu. It ships the original art and a 2× and 4× AI-upscaled version (Real-ESRGAN) chosen in the video options. Ares appeared in 1998 and its source code and media were released in 2008: the game’s data is in the repository and the release, under CC BY-NC-SA 3.0, and the code under LGPL 3 or later. Version 1.0 (October 21) is a zip of about 142 MB; on first launch it downloads about 12 MB of sound effects. 98 of its last 100 commits list Claude as a co-author.
You needYou don’t need your own copy: the game’s data was released by its author in 2008 under a non-commercial Creative Commons licence and is included. 64-bit Windows 10 or 11, and an internet connection once, on first launch, to download the missing sound effects.
Prince of Persia 2: The Shadow and the Flame (Mac)
dmucli/pop2-port
An unofficial native port of the 1993 Macintosh version for macOS, Linux, Recalbox, and retro handhelds. The original 68k program was decompiled with Ghidra and translated, function by function, into C, and a reimplementation of the classic Mac Toolbox runs it on top of SDL. The translated code is in the repository (src/game/), but the Ghidra project and the game data are not: the data is read from a disk image of your copy. It adds save states with pictures, rewind, an on-screen menu, statistics, gamepad support, and optional cheats (infinite health or time, jump to any level). It is verified by replaying every call on the original 68k code with the Musashi emulator, which only remains in development builds. Version 0.2 (October 17) publishes packages for macOS, Linux (x86_64 and arm64), Recalbox, and PortMaster of 1.2 to 2.5 MB; there is no Windows version. 63 of its last 100 commits list Claude as a co-author.
You needYour own disk image of the Macintosh Prince of Persia 2 (floppy, CD, or hard disk) in a common format (.hfv, .dsk, .img, .image, .toast, .iso, .cdr, or MacBinary .bin); an emulator disk (Basilisk II, SheepShaver, Mini vMac) with the game installed also works. Plus macOS 12 or later on Apple Silicon, 64-bit Linux (x86_64 or arm64), Recalbox, or a handheld with PortMaster.
