• .NET 10, the latest of a more modern, cross-platform, high-performance version of .NET Framework
  
• 64-bit support. osu! finally takes advantage of computers made after 2010!
  
• Support for Linux. Natively. Yes, that means Wayland!
  
• Modern renderers, like DirectX 12 and Vulkan
  
• Hardware video decoding
  
• Various rewrites of parts of the engine
  
• Many QOL features, such as a backported Visual Settings and modern star calculation!
  

• Text input is buggy. You can type into multiple textboxes at once, which is a little funky.
  
• MMSliders don't work yet due to a graphical bug, for now I've forced the game to use peppy/worm sliders

  Rendering APIs

  
  By default, RetroGecko will use OpenGL as its renderer. In most cases this appears to be the fastest renderer, but FNA comes with several graphics backends.
  
  To change the renderer in use to experiment with performance, see the options menu in-game.
  In the case you've selected a renderer which crashes or doesn't work, you can open your osu!.<user>.cfg file and change the GraphicsBackend option.
  
  
  
  
• OpenGL (default)
  
• Vulkan
  
• D3D11 (Windows only*)
  
• D3D12 (Windows only, unsupported at the moment)
  
  
  Changing the renderer from OpenGL will usually result in slower performance on desktop GPUs, but on integrated/mobile GPUs you may see a performance improvement from using Vulkan.
  
  Your mileage may vary!
  
  *technically might possibly work on Linux with libdxvk installed if you rebuild FNA3D with FNA3D_DXVK_NATIVE why would you do this i dont know but im being held at gunpoint forced to tell you this
  
  

  Special Thanks

Yeah, you can feel free to download and run it if you still have the link, but don't log in with it or else you'll get banned.

I just don't want people to accidentally run it and get banned D:

RetroGecko b205 is out, with the following additions and fixes!

• Add 'beta' marker to branding
  
• Fix some exceptions not being reported properly
  
• Replace image loading with ImageSharp (resulting in a smaller filesize for the osu.dll!)
  
• Allow setting Background Dim to 100%
  
• Fix flashing being too intense
  
• Fix options in RetroGecko options tab not saving
  
• Compress osu!.db (now called retrogecko_beatmaps.db), resulting in significantly smaller filesizes for large volumes of beatmaps.
  
• Only show one storyboard error when loading beatmaps (should help with newer maps)
  
• Try to lower BASS buffer sizes. Should result in lower audio latency if your computer can support it. I also want to try using WASAPI at some point.
  
• Introduce a basic update checker
  
• Remove a couple outdated libraries, replacing them with the .NET 9 BCL equivalents
  
• Make beatmap importing a background job
  

RetroGecko b213 is out. Just a small hotfix this time!

• Fix beatmap importing causing crashes in the audio engine
  
• Fix not being able to toggle gameplay settings e.g. hit lighting
  
• Fall back to loading .jpg files if a .png was not found
  
• Allow loading menu-background from skins
  
• Fix background dim setting only going down to 30%
