KEGS-OSX is an emulator that allows users to run Apple IIgs software on modern macOS operating systems. The software recreates the Apple IIgs environment with high precision, enabling a nostalgic experience for old-school computer enthusiasts.
The key features of KEGS-OSX are fast 65816 emulation and the ability to emulate low-level 5.25" and 3.5" drive accesses, including nibble-copiers. KEGS-OSX can also emulate classic Apple II sound and 32-voice Ensoniq sound, which is played in 16-bit stereo at 48KHz (converted to 16bit 44khz, as that is the best Macs can do). Additionally, KEGS-OSX can emulate all Apple IIgs graphics modes, including border effects, and can handle mixed displays (superhires at the top, lores at the bottom).
KEGS-OSX always performs 60 full screen video updates per second and comes with both mouse and joystick support. It can emulate all Apple IIgs memory "tricks" for full compatibility, and its low-level ADB keyboard and mouse emulation enable Wolfenstein 3D to run. The clock chip emulation makes the Unix time available to the Apple IIgs, while the emulated battery RAM remembers control panel settings.
In this release, the sources are now compiled with GCC 4.01 from XCode 2.4.1, and the sources are now universal, working on both PowerPC and Intel processors. The sources are also compiled on an iMac Intel computer, and a small fix for backward compatibility with Mac OS 10.3 without Core Data calls has been added (for Yannick).
Overall, KEGS-OSX is an excellent software tool with several impressive features that allow users to emulate classic Apple IIgs systems on modern UNIX-based platforms with ease. Its optimization for Cocoa integration and multi-media capabilities make it a valuable addition to any software collection.
