Atari800 is an Atari 8-bit computer (400, 800, and XL and XE series) and Atari 5200 game system emulator for DOS, Windows, Amiga, Atari ST, Mac, and Linux/UNIX. It includes support for Atari cartridge ROMs, popular Atari disk images files, running Atari binaries directly from the host system, and accessing the host filesystem from within the emulated Atari.
The Catweasel Floppy Read/Write Tools are a set of tools for owners of Catweasel MK1 ISA and Catweasel MK3/MK4 PCI universal floppy disk controllers. cw2dmk reads several kinds of floppy disk, some of which ordinary PC controllers have trouble with, and save them in the DMK disk image format used by TRS-80 emulators. It can also handle any disk written using a Western Digital 177x/179x floppy disk controller, a PC-style NEC765-compatible controller, or a Digital Equipment Corporation RX02 controller. dmk2cw writes any DMK image back to a floppy. jv2dmk and dmk2jv3 convert images between DMK and JV1 and JV3 formats without requiring Catweasel hardware.
Dapple ][ is an emulator for the Apple ][, ][+, and //e computers (and to some extent the //c) supporting from 48-3136 K RAM, parallel ports, 2 Disk ][ drives, and a real 1.40 MB floppy drive. It is written in gcc and nasm (the nasm component is not currently source-available). It supersedes Dapple, which has many of the same features.
Game Launcher is a cross platform, universal front end for emulators. The main goal is to provide a user interface that is easy to use and attractive, yet does not look like a traditional user interface with windows and such. Game Launcher should work with any emulator, but it has been known to work with MAME, Nesticle, RockNES, zSNES, snes9x, Callus, Stella, z26, and Versions are available for Unix, DOS, and Windows.
