About:
DASM is a versatile macro assembler designed for cross-platform development on 8-bit microprocessors like the 6502, 65C02, and 68705. It features a powerful macro preprocessor that supports multi-pass assembly, conditional compilation, and file inclusion. Its primary value is enabling reliable, repeatable builds for retro computing, embedded systems, and game development projects.

Key Features:

Cross-platform support for multiple 8-bit architectures (6502, 68705, etc.)
Powerful macro preprocessor with conditional compilation
Multi-pass assembly for complex label resolution
Flexible output formats for various emulators and hardware

Use Cases:

Developing software for retro computers and consoles (e.g., Atari 2600, NES)
Programming embedded systems with 8-bit microcontrollers
Maintaining and patching legacy assembly codebases

Alternatives:

ca65 – Part of the cc65 suite; more modern but with a steeper learning curve and larger toolchain.
vasm – Highly modular and supports many targets; often considered a direct and powerful alternative.
