Crossrunner

Emulation Accuracy

• Crossrunner emulates the machine at a much lower level than any other Apple IIGS emulator.

• Emulated software will look and feel like the real hardware.

• Developers can test software under emulation with confidence, knowing that it closely matches the hardware.

Ease of Use

• Intuitive Graphical User Interface for all functionality.

• Fully customisable interface and customisable monitor settings.

• 1:1 keyboard mapping

  • No Function Keys required for basic tasks (e.g. Control Panel), but full ADB extended keyboard functionality is supported.

  • If you are using a standard keyboard then use the keys in the same positions. Alt → Open Apple, Windows →  Close Apple, Break →  Reset.

  • If you are using a real Apple IIGS keyboard (e.g. with a Wombat) then it is even easier. Open Apple →  Open Apple, Close Apple →  Close Apple. Control+Open Apple+Esc will bring up the Control Panel, just like a real machine.

• Automatically adjusts emulation settings for games to ensure full compatibility and maximum enjoyment.

• Drag and drop disk images onto drives.

• Paste text into the emulated machine.

Modern

• Supports modern Operating Systems (x64 and ARM64)

• Supports High DPI monitors

• Allows XBox controllers to be used as joysticks, or as SNES controllers (via emulated SNES MAX card)

• Supports Ethernet via Uthernet II emulation

• Automatically downloads from archive.org

• Save snapshots of the machine's state and restore from those snapshots

Debugging

• Fully featured debugger. Step through code, set complex breakpoints, view memory and video pages in real time, visually “race the beam”, profile code, and lots more.

• The only emulator that allows source level debugging – whether your program is written in assembly language, C or Pascal.

Development

• Built-in ORCA compatible development environment. Compile ORCA/C and ORCA/Pascal code inside Crossrunner. Run ORCA Shell scripts.

• Also supports Golden Gate and Merlin 32.

• Seamlessly interoperate between the native filesystem, mounted ProDOS / DOS 3.3 filesystems, Apple Filing Protocol shares and VEDrives.

Scripting

• Fully extensible through powerful scripting integration.

• Build game cheats and assistants, debugging tools, and automate common tasks all through the scripting engine.

Cross Platform

• Windows version available now.

• Mac and Linux ports coming soon.
