Fixture Runner - Loading and execution infrastructure

Structs

FixtureRunner

Canonical entry point of the systemless library.

FixtureRunnerConfig

Configuration knobs for FixtureRunner. Use FixtureRunnerConfig::default for the canonical defaults (10M-instruction budget, 0x10000 load base, arrow-keys NOT remapped to numpad, guest-controlled menu bar) — only override fields you actually need.

VfsFileSnapshot

VfsFileStat

VfsFileSummary

Enums

MenuBarPolicy

Host presentation policy for the classic Mac menu bar.

Constants

DEFAULT_POWERPC_SCREEN_DEPTH

Default direct-color display depth for native PowerPC applications. Imaging With QuickDraw (1994), p. 6-16, defines 16 bits per pixel as a supported Color QuickDraw screen and offscreen graphics-world depth.

DEFAULT_REALTIME_CPU_MHZ

Default emulated CPU speed from the canonical machine profile.

DEFAULT_REALTIME_INSTRUCTIONS_PER_SECOND

Default 68K realtime CPU budget used by scripted realtime mode and by GUI sessions that do not load a PowerPC executable.

DEFAULT_REALTIME_PPC_CPU_MHZ

PowerPC clock exposed by the native 604 machine profile. The Power Macintosh 9500/120 paired a 120 MHz clock with the same 604 processor reported by the PPC Gestalt implementation. https://support.apple.com/en-hk/112050

DEFAULT_VBL_HZ

Compact Mac video hardware refreshes at approximately 60.15 Hz.

Functions

decode_fakeptr_pc

If pc matches a GetTrapAddress fake-pointer pattern, return a human-readable hint identifying the trap that the game most likely tried to JMP/JSR through. Else None.

default_realtime_instructions_per_tick

Returns the per-VBL instruction budget for the loaded guest architecture.

dump_wait_stats

Print the wait-elision diagnosis counters (no-op when env unset).
