Nostlan (formally Bottlenose) is a high quality front-end launcher for gaming emulators which supports Windows, Linux and MacOs. It's currently capable of launching more mainstream emulators with nice features and its future looks quite bright!

Current Features

  • unified UI for mouse/gamepad interaction
  • designed for UHD displays and projectors
  • checks multiple database sites for the highest quality box art
  • nostalgic UI themes for each supported console
  • fancy scroll direction alternation effect on rows in cover view mode
  • most controllers connect to Bottlenose automatically, no setup required including Xbox One, PS4 Dualshock, and Switch Pro controllers
  • gamecube controller adapter supported with gca-js
  • advanced customization: edit launch commands and change game art


Most Recent Changes


  • NES game library and Mesen emulator support! I consider Mesen to be the best nes emulator but it's not available on macOS and can't be run with wine. em-fceux, a NES emulator ported to javascript will be bundled built-in with Nostlan in the future.

  • Ryujinx support (alternate Switch emulator that can run 32bit games, unlike Yuzu)

App UI

  • shows emulator wiki pages for games in the manuals section of the open box menus (only works for wii and switch right now)

User Experience

  • search for games on the game library view just by typing (no search bar), just like with Windows File Explorer

  • increased performance in the game library view due to the use of thumbnail images. Nostlan automatically switches to using the full res game art when you select a game. Scrolling and animations are now smooth even for really large libraries!

  • In your preferences you can now edit or delete the key command Nostlan uses after launching some emulators, such as Yuzu, to put them in fullscreen mode.
