gb-recompiled AGENTS.md

gb-recompiled AGENTS.md is an instructions file for Codex, OpenCode from arcanite24/gb-recompiled. It costs 2,762 tokens per session, scanned A, original, MIT.

A set of repository instructions for developing GB Recompiled, a project that turns Game Boy ROM programs into generated C code linked to a shared runtime. A ROM is the software image read by a Game Boy.

In plain words
What is it for?
Use it when building or testing the recompiler, working on Game Boy or Game Boy Color support, checking accuracy, generating projects, or following the project's documentation and validation rules.
Why use it?
It explains where the compiler, runtime, tests, tools, documentation, and generated output live, reducing the chance of changing the wrong part or using copyrighted game files incorrectly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gb-recompiled AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Working on GB Recompiled

Project and documentation map

GB Recompiled turns Game Boy ROMs into generated C and links that code with a shared runtime.

The main areas are:

  • recompiler/: ROM loading, decoding, analysis, IR, code generation, and the gbrecomp CLI
  • runtime/: CPU fallback, mappers, PPU, DMA, timers, audio, persistence, SDL, and ImGui
  • tests/: repository-owned synthetic and unit regression tests
  • tools/: accuracy, trace, differential-log, frame, audio, and benchmark helpers
  • roms/: local test ROMs; do not commit copyrighted commercial ROMs
  • output/: ad hoc generated projects and launcher builds
  • logs/: durable repro captures, state dumps, frame captures, and benchmark results

Documentation roles:

  • README.md: short public introduction and successful first build
  • RUNTIME.md: generated-executable controls and diagnostics
  • ACCURACY.md: current external-ROM test snapshot
  • GBC.md: CGB implementation and validation status
  • ANDROID.md: Android generation and APK workflow
  • GROUND_TRUTH_WORKFLOW.md: trace-assisted coverage, including its limits
  • NATIVE_PATCHES.md: exact-ROM native replacement manifest and callback ABI
  • PORT_MODULES.md: exact-ROM read-only port/frontend module ABI
  • TODO.md: prioritized live backlog
  • docs/CODE_IMPROVEMENT_AUDIT_2026-07-12.md: audit evidence and completed P0 remediation
  • docs/RECOMPILER_CORRECTNESS_AUDIT_PLAN.md: current correctness roadmap
  • docs/NL0_POST_WIN_PERFORMANCE_TRUTH_2026-07-14.md: three-game attribution, estimator, build footprint, and NL-0 decision
  • docs/NL1_ARITHMETIC_TIMER_RESULT_2026-07-14.md: retained timer optimization and scalar-oracle evidence
  • docs/NL2_LAZY_PPU_RESULT_2026-07-14.md: rejected lazy-PPU experiment and measured limits
  • docs/APU_EVENT_BATCHING_RESULT_2026-07-14.md: retained lazy APU scheduling and deterministic PCM evidence
  • docs/NL4_GENERATED_BUILD_RESULT_2026-07-14.md: retained generated chunking and compiler-memory evidence
  • docs/NL3_POST_SCHEDULER_REPROFILE_2026-07-14.md: post-scheduler compiled-region eligibility decision
  • docs/NL5_NATIVE_PATCH_SDK_RESULT_2026-07-14.md: native replacement tracer-bullet design and gates
  • docs/NATIVE_RECOMPILATION_STRATEGY_2026-07-14.md: active performance and AOT execution strategy

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
