The Infinite Mac project, which simulates the Macintosh environment from 1984 to 2005, now supports running various versions of the BeOS operating system directly in a web browser. The system utilizes the DingusPPC emulator, which was updated to improve compatibility with BeOS hardware requirements.
The integration process required several technical fixes for the emulator. These included correcting ADB emulation to prevent modifier keys from appearing stuck, fixing color depth notification sequences, and adding support for little-endian video memory access. Additionally, the developer adjusted the emulator to handle HFS partition mounting and ROM mapping more accurately.
To ensure compatibility with early versions of BeOS, such as Developer Release 8.2, the developer implemented a system date override to bypass a software expiration date set for April 1, 1997. The project also features dynamic configuration to match screen resolutions with browser window sizes.
The developer expanded the project's library by adding system CD images, including early versions of Rhapsody and Mac OS X. These files are hosted on Cloudflare R2 to ensure reliable streaming, as the developer noted increasing instability when loading data directly from the Internet Archive.
