Robert Szeleney released version 3.9.1d of his OS,
SkyOS, including a number of fixes, while he ported the first game to SkyOS, Quake I (

Syllable also recently got a port of Doom and Quake. In other small OS news,
ReactOS has a preliminary graphics system able to run simple Windows binaries (
screenshot, running inside the Bochs emulator). The team expects more and better compatibility to come when the WINE port gets finished.
