The Birdman64 1.1.0 added local split-screen two-player multiplayer to the native port of Pilotwings 64 for PC. The project changelog registers the change in October 13, 2026. Now, each participant can control their own pilot during the same flight test. However, version 1.1.0 did not yet appear among the public packages on the release page consulted on this date.
Birdman64 runs the Nintendo 64 game natively on Windows and Linux, without a conventional emulator. To do this, it compiles the decompiled open-source code of the game on the user's computer. Furthermore, the program requires its own copy of the American ROM of Pilotwings 64. The project does not distribute the original game.
Birdman64 1.1.0: how does multiplayer work?
In the main menu, the player will be able to choose between one or two people. In split-screen cooperative mode, both perform the same test simultaneously. According to the developer, each pilot maintains independent controls, objectives, HUD, sounds, results, replays, and photos. The feature also works with all aircraft and extra activities listed in the changelog.

The image shows the side-by-side split. In addition to this format, the menu allows choosing a horizontal split, with the images one above the other. The user can also assign a second controller, enable collisions between pilots, and share the best score with the main progress file.
Each player's radar displays the other pilot with a light blue arrow. This way, participants can locate their flight companion. The feature is described in the changelog, but has not yet been submitted for independent evaluation by Allves Games.
What else changed in the update?
Besides multiplayer, version 1.1.0 fixes a bug that could close the game after saving a photograph. Snow now also fills the entire screen in widescreen, without limiting the image to the old 4:3 aspect ratio. Finally, the missing button warning remains visible when controller remapping expires.

These changes are in addition to the previous port features. Among them are expanded aspect ratios, modern controls, graphic filters, and high refresh rates. However, results vary depending on the computer and settings. The changelog does not present a new independent benchmark for version 1.1.0.
When will it be possible to download Birdman64 1.1.0?
As of the inquiry on October 13, official releases page it still identified version 1.0.2 as the most recent one. It offers packages for Windows x64 and Linux, but it predates the 1.1.0 multiplayer. Therefore, downloading these files does not guarantee access to the novelty described here.
The code and changelog for 1.1.0 are already available in the repository. However, source code is not a ready-to-use installer. For this reason, this article does not present a button labeled as an updated download for version 1.1.0 until there is a corresponding verified package.

Birdman64 is different from other Nintendo 64 game initiatives, such as the Conker Recompiled. Meanwhile, the native port of Wayne Gretzky's 3D Hockey also explores modern controls in a platform classic. Each project has its own requirements and development.
For now, local multiplayer is documented and illustrated by the developer himself. Confirmation of a 1.1.0 installer and stability testing with two controllers still depend on further checks.
