GSSquared Apple II GS Emulator version 0.8.0 Released

From Jawaid Bazyar:
I am pleased to announce the release of GSSquared v0.8.0.

GSSquared is an Apple II series computer emulator.

Supported platforms

• Apple ][
• Apple ][ Plus
• Apple //e
• Apple //e Enhanced
• Apple //e Enhanced with 65816 CPU and Super Hires Video
• Apple IIgs ROM 01

Pre-built binaries

• macOS (Intel and Apple Silicon)
• Windows 10+
• Linux AppImage (should run on many Linux distros; tested on Ubuntu 22)

This release brings full 3.5″ floppy support on the Apple IIgs, a much-improved Control Panel for managing disks, and better handling when you quit with unsaved disk changes.

Features

• Apple IIgs 3.5″ floppy drives now support WOZ disk images for reading and writing, including many copy-protected titles. Copy-protected titles include Alien Mind, and Tomahawk.
• 5.25″ and 3.5″ floppy emulation has been significantly improved. Copy-protected WOZ images that previously failed should now work, and changes to mounted disks can be saved back to the original image file when you unmount.
• The Control Panel has new, clearer drive icons for 3.5″ AppleDisk drives and hard drives. Icons match the machine you are emulating — Disk II on early Apple II models, AppleDisk on the //e and IIgs.
• BazFast, the built-in SmartPort hard drive, can now mount multiple disk images at once. Drag a .pmap file onto a BazFast icon to load a whole set of volumes in one step — handy for multi-disk setups like a hard-drive collection with separate ProDOS volumes.
• When you quit or power off, GSSquared now properly asks whether to save any disks that have unsaved changes.
• You can launch GSSquared directly into a specific machine from the command line: -p PLATFORM (for example, -p iigs). Closing the window will then exit the emulator automatically.

Accuracy

• Floppy disk timing and head movement are more accurate, which helps games and copy-protection schemes that depend on precise disk behavior.
• Mounting a disk image on the wrong kind of drive (for example, a 140K floppy image on a hard drive) now shows a clear error instead of failing silently.

Bug Fixes

• The debugger open/close key is now F10, so it no longer conflicts with keys used inside Apple II software.
• Fixed a Windows build issue.

Internals

• The floppy and IWM disk code has been reorganized and rewritten as a foundation for future storage improvements.
• Documentation for disks, WOZ images, and BazFast has been updated.
