UAE

UAE is a free Amiga emulator written in C.

Emulated hardware

A 68000/010/020/040 CPU, optionally a 68881 FPU
OCS, ECS and AGA Graphics Chipset (including sprite-playfield collisions)
Up to 2MB Chip RAM and up to 8MB Fast RAM, or 8MB Chip RAM without Fast RAM
Up to 64MB Zorro III Fast RAM, independent of Chip RAM setting (68020+ only)
Up to 1MB Slow RAM, for extended compatibility with problem software
Up to 8MB of graphics card memory, usable by software that supports Picasso 96 compatible graphics cards
4 x 3.5" floppy disk drives (DF0:, DF1:, DF2: and DF3:). It's not possible to read Amiga disks, so these are emulated with disk files.
A hard-disk: either a harddisk image file or part of the native filesystem
Joystick support (with option of mapping joystick to numeric keypad)
Mouse support
Ability to run in various screen modes (for better display quality or better speed)
Full stereo sound support, consisting of 4 x 8bit channels
Simple parallel and serial port support. Note: the parallel port is not really implemented. Though it's sufficient for printing.
State-saving. You can save the state of your emulated Amiga and continue later on.
