Emulators

The most complete and polished emulator for Atari 8-bit systems

Excellent portable emulator for Atari 8-bit home computer systems

Atari800Win Plus

Excellent emulator for Atari 8-bit home computer systems with long legacy usage

A Unix and Win32 based emulator of the Atari eight bit computers, namely the Atari 400 and 800, the Atari 400XL, 800XL and 130XE, and the Atari 5200 game console. The emulator is auto-configurable and will compile on a variety of systems (Win32, Linux, Solaris, Irix).

Obsolete, but good emulator for Atari 8-bit home computer systems. Author of this emulator also owns original ROM images, usable for other Atari emulators.

A8E is a freeware Atari 800 XL emulator. It uses the SDL library for the user interface and the audio and graphics (via OpenGL) output.

Development tools

MADS is a multi-pass crossassembler designed for 6502 and 65816 processors. Binaries are generated mainly for Atari 8-bit systems (supported are AtariDosII and SpartaDOS X formats).

Mad Pascal Compiler

Great new cross development system for 6502 microprocessor by Tebe, resembling Pascal, specifically made for Atari home computers. It is based on Sub-Pascal 32-bit real mode compiler for 80386+ processors v. 2.0 by Vasiliy Tereshkov, 2009

A freeware 6502 cross-assembler Windows with original syntax extensions. It is mainly targeted at Atari 8-bit computers, but it can be also used for programming Atari 2600/5200/Lynx, Commodore C64, Apple ][ and others.

This is a fast interpreter for the BASIC language on the Atari 8-bit computers and the Atari 5200 console.

cc65 is a complete cross development package for 65(C)02 systems, including a powerful macro assembler, a C compiler, linker, librarian and several other tools. It is based on a C compiler that was originally adapted for the Atari 8bit computers by John R. Dunning.

A 6502 command-line cross-assembler that is compatible with the original Mac/65 macro assembler released by OSS software. The aim of ATasm is to provide Atari home-brew coders with a comfortable and powerful toolset.

A C-compiler for 6502-based platforms creating optimized and readable assembler code. The language is 95% standard C with a few limitations and a few extensions.

A middle-level programming language for 8-bit microprocessors, this language focuses on performance, compactness, simplicity and readability.

TurboBasic XL parser tool

This program parses and tokenizes a TurboBasic XL listing in a flexible format and produces any of three different outputs

A new high level programming language for MOS Technology 6502 microprocessors. It is meant to be used for development on 8bit computers like Atari 800, C64 etc. A work in progress!

Effectus Compiler

Interactive 6502 disassembler for Atari binary files on Windows.

Graphics editors

The Graph2Font (G2F) program treats the image as fields with dimensions of 4x8, 2x8, 8x8 pixels. At the beginning this program had been used only to convert graphics to chars but now it also allows you to do multicolor graphics for the 8-bit Atari.

Atari Interlace Studio

Excellent graphics manipulation program for most Atari 8-bit Atari graphics formats by Tomasz "TeBe" Biela.

A set of utilities for easier developing on Atari 8-bit machines, including editors for graphics, character sets, different text modes, player/missiles and even editing source code with direct compiling to selected programming language

RECOIL - Retro Computer Image Library

RECOIL is a viewer of pictures in native formats of Amiga, Atari 8-bit, Atari Portfolio, Atari ST, Atari Falcon, Commodore 64, Macintosh 128K, MSX, SAM Coupe and ZX Spectrum computers.

Excellent player/missile editor for Atari, inspired by the "Atari Player Editor" by Paul "Playsoft" Lay. The application was written in javascript, it works directly in the browser.

Interesting display list editor for mixing different text and graphic modes, written in JavaScript. It allows you to automatically generate source code of your custom display list.
