About
Crossrunner emulates the GS at a lower level than the others and is the reference many developers test against: cycle-accurate timing, so the Ninjaforce Megademo and the FTA disks look and feel like the hardware. It pairs that with a friendly GUI, 1:1 keyboard mapping (Alt and Windows keys as Open and Closed Apple, Ctrl-Alt-Esc for the Control Panel), drag-and-drop disks, text paste and a cross-development environment with a debugger. Windows only.
