M1PP Launcher v4.0b

Added

  • Added a standard Windows Setup.exe installer.
  • Added packaged updater support.
  • Added launcher logging under %LOCALAPPDATA%\M1PPLauncher\logs.
  • Added Discord Rich Presence support.
  • Added built-in tosu support for telemetry/RPC.
  • Added uninstall for very simple and easy uninstall.
  • Added console
  • Added Status
  • Added Shortcuts (quick access buttons)

Changed

  • osu!stable is now the active supported client path.
  • osu!lazer is temporarily disabled because M1Lazer is currently shut down for now.
  • Updated the launcher UI for the v4.0b release.
  • Updated the News tab slides and links.
  • Updated the bundled RelaxPatcher build. (Though RelaxPatcher seems to not work)
  • Reworked the launcher build process so the updater is built first and bundled into the launcher.
  • Standardized the Windows build path through build.bat and build-installer.bat.
  • Repo QoL, and other structural changes.
  • Prob some other stuff I can't think of because this took 5 months to release.. ?

Fixed

  • Fixed missing PySide6 bundling in the frozen executable.
  • Fixed qasync backend initialization by forcing PySide6 before import.
  • Fixed fresh installs not being able to launch osu because installdata.json was missing.
  • Fixed launcher-side osu startup polling so it stops after launch verification/injection instead of polling for the entire osu session.
  • Fixed the Mods folder button to use the installed launcher mods directory.
  • Fixed update prompt behavior so stale legacy version metadata does not trigger false update prompts.
  • Fixed installer uninstall cleanup for launcher files, settings, logs, mods, and shortcuts.
  • Prob some other stuff I can't think of because this took 5 months to release.. ?

Removed

Quite a bit of stuff

Notes

  • Download and run M1PPLauncherSetup.exe.
  • Windows SmartScreen or antivirus warnings may still appear because the executable is unsigned and new.
  • M1Lazer is temporarily unavailable, so the lazer option is greyed out.
  • This launcher is for M1PP/private osu!stable routing and is not for official Bancho use.

Also, stop ignoring the text and use "M1PPLuncherSetup.exe" to install the launcher


Hotfix 5/27/26 | Relax Patcher now works as intended lol

IF YOU WANT TO INSTALL THE LAUNCHER, USE THE M1PPINSTALLER.EXE, DON'T USE THE OTHERS

M1PP Launcher Beta 3

Lots of bugfixes. You can download files you can find on https://4ayo.ovh/m1pposu/files/launcher/latest/ here on GitHub.

Bugs Fixed

  • The uninstall process may trigger some anti-virus software.
  • The uninstaller sometimes leaves an empty folder and does not delete it.
  • Mods not injecting.
  • Installer using corrupted osu! installations.
  • Shortcut icons missing.
  • Launcher acctidentally corrupting its own osu! installation during updates (your maps and skins were unaffected by this)

Unfixed Bugs

  • osu! needs to be launched multiple times on first-time install. This is mostly due to the osu! updater not passing the --devserver argument to the osu! client after an update (however it is fixable)
  • It takes a very long time to launch the M1PP Launcher app.
  • Linux and Mac are not currently supported.
  • The installer looks like it's stuck at 99%
  • The launcher needs a logging system so we can diagnose issues more quickly.
  • The code needs more documentation and a cleanup.

M1PP Launcher Beta 2

The first release of the new beta. You can download files you can find on https://4ayo.ovh/m1pposu/files/launcher/archive/BETA2/ here on GitHub.

Known Issues

  • It takes a very long time to launch the M1PP Launcher app.
  • The uninstaller sometimes leaves an empty folder and does not delete it.
  • Linux and Mac are not currently supported. This is planned, but in the meantime, you can try your luck using WINE.
  • The uninstall process may trigger some anti-virus software. We are currently using an extremely hacky implementation with .bat files... yeah.

  • The launcher needs a logging system so we can diagnose issues more quickly.
  • The code needs more documentation and a cleanup.
