Following its unveiling at the Chaos Communication Congress, developer hikari_no_yume is actively developing Loss32, an experimental OS blending Win32 apps via Wine and ReactOS elements on a Linux kernel. It aims to emulate classic Windows interfaces while supporting native Linux apps, with a Debian-based proof-of-concept planned.
Since proposing Loss32 at the 39th Chaos Communication Congress in late December, developer hikari_no_yume has begun building the project using mature open-source tools. Unlike ReactOS, which builds a custom Windows NT-compatible kernel from scratch after nearly three decades in alpha, Loss32 leverages the Linux kernel, Wine compatibility layer, and ReactOS userland components for quicker advancement.
This enables a Windows 95/98/XP-like experience without reinventing the wheel, plus native Linux application support. It simplifies setup for users seeking Windows functionality on Linux without manual Wine configurations or desktop tweaks. ReactOS developers note potential driver incompatibilities with a Linux base.
Loss32 is not yet downloadable, but an initial proof-of-concept on Debian Linux is forthcoming. Contributions are encouraged via the official website, underscoring efforts to merge Windows and open-source worlds.
