Features

• 68k CPU emulated using the Castaway 68k emulator.
• GUI implemented using the Simple Directmedia Layer (SDL). The SDL has been ported to many platforms, most notably to Unix/X11 and Win32.
• Supports all Atari ST(tm) video modes. Pixel doubling for resolutions smaller than 640x400.
• Configurable screen refresh rate and system timers.
• Configurable RAM size
• Supports TOS versions 1.0, 1.2, 1.4 and EmuTOS.
• Floppy drive support. Access to either the floppy drive (/dev/fd0), or virtual drives (FAT12 file system image files). Support for single-sided, double-sided, double density or high density floppies.

Requirements

• Floppy disk images. The distribution contains an example disk images, and a tool to create an empty disk image.
• TOS ROM image. The distribution floppy disk image contains a program to copy version 1.x ROM contents to disk. Copy this program to a real DD floppy disk, search the attic for your old faithful ST, dust it, crank it up and get a ROM image. Or go for EmuTOS. The distribution does not contain a ROM image.
• SDL runtime. The distribution contains a (possibly outdated) version of the SDL runtime library. Get SDL runtime libraries here.

Non-Features

• No YM2149 sound chip emulation.
• No serial and parallel ports.
• No Joysticks.
• Monochrome monitors are no longer supported, as the support for 1 bit-per-pixel framebuffers has been discontinued. (Don't read this wrong: monochrome mode works, as monochrome can be displayed nicely on a color monitor, thank you!)
