## プロジェクトの歴史と使われ方

ATasm is a mostly MAC/65-compatible 6502 cross-assembler for Atari 8-bit development. It lets programmers write Atari assembly on modern hosts while producing Atari-native load objects, disk images, and emulator-related outputs.

### プロジェクトの歴史

The README traces ATasm to Mark Schmelzenbach in 1998 and explains that it was created from a desire for a fast Atari-specific cross-assembler after using OSS MAC/65 on real hardware and finding other cross-assemblers lacked Atari-specific directives and conveniences. The current fork documents modifications by Peter Hinz from 2021 through 2025.

The version history records an initial public 0.90 release, GPL release at 1.00, Atari-specific output work such as XFD/ATR and emulator state-file support, undocumented opcodes, MAC/65 compatibility improvements, list/debug output, CC65 header generation, VS Code/Altirra bridge symbol dumps, long branches, trigonometry table helpers, procedure scopes, and .GUARD/.NOTIFY directives.

### 採用の歴史

ATasm occupies a niche but durable package-manager slot: retrocomputing developers need a small native assembler that can be scripted from makefiles and editors instead of running original Atari tools inside an emulator. The supplied metadata shows Homebrew, Fedora/DNF, and Nix packaging.

Its adoption is tightly connected to Atari emulator and cross-development workflows. The README explicitly names Atari800Win, Atari800, and Atari++ state-file targets, and later releases added outputs used by CC65 and VS Code/Altirra tooling.

### 使われ方

The command is `atasm [options] <file.m65>`. Users enable undocumented opcodes, raw binary output, include paths, predefined symbols, XFD/ATR output, emulator state-file merging, symbol/list output, CC65 headers, ATasm include files, and JSON symbol dumps for editor integrations.

### パッケージ好きにとっての重要性

ATasm is a compact example of why niche retro tools survive in general-purpose package managers: it is small, C-based, scriptable, compatible with old source idioms, and bridges modern build systems with emulator/debugger ecosystems.

### タイムライン

- 1998: Original ATasm copyright and project origin.
- v0.90: Initial public release.
- v1.00: Package explicitly released under the GPL.
- 2019: v1.09 fixed multiple buffer-overflow CVEs.
- 2025: v1.30 added .GUARD and .NOTIFY directives.

### Related projects
