emucap 0.18.0

Core binaries: Windows x86-64, Linux x86-64, and macOS Apple Silicon. Emulator adapters are built separately using the maintained recipes.

Added

• Xbox host API 3 adds frozen native RAM batches with ordered, overlapping ranges and an NV2A
  writer barrier. Rebuild with adapters/xemu/build.sh.
• openMSX frozen read_memory_batch reads multiple validated ranges in one native command and
  reports a native stop boundary (runtime_generation, stop_epoch, memory_mapping_epoch).
• Agent-controlled openMSX host pacing through debug operation execution_speed: arbitrary
  supported percentages or unlimited speed, with native readback and preserved execution state.
• Common batch and pacing contracts: adapters advertise memory_batch_capability and
  execution_speed_capability with the method; Control admits requests against them before
  forwarding, verifies replies, and returns busy for pacing changes during another operation.
• NP2kai, MAME PC-98, MAME Neo Geo, Mesen2, Mednafen, Flycast, Dolphin, DeSmuME, PCSX2,
  PPSSPP and Mupen64Plus advertise read_memory_batch and execution_speed. Dolphin, DeSmuME,
  PCSX2 and PPSSPP status now report frame.
  NP2kai paces its own frame loop; MAME keeps its native governor with a maintained throttle hook.

Changed

• Compact, self-contained agent guidance uses live tool metadata for memory and CPU selection;
  recording setup and interpretation are available through debug(operation="describe").
• NP2kai frame steps, input pulses and pointer moves follow the pacing policy (launch default 100
  percent). Set unlimited for maximum-speed stepping. A paced advance that would outlive its
  host budget returns interrupted with reason: "host_deadline" and the reached count.
• NP2kai and MAME read_memory read without device side effects where the native view allows it,
  so PC-98 graphics VRAM reads no longer drive GRCG/EGC latches.
• openMSX requires host API 6 (patch 0005); rebuild the native host with adapters/openmsx/build.sh.
• MAME and NP2kai builds scrub Homebrew toolchain overrides like the other native adapters.
• Mesen2 requires host API 5 (patch 0014). Mesen launches are silent unless sound:true, and
  Mesen read_memory uses the debug view. freeze_policy.savestate_safe moved to the dynamic
  status field halt_savestate_safe.
• Mednafen frame steps, deferred frame operations and probes follow the pacing policy, and
  pause from a running guest stops at the current frame boundary instead of one frame later.
  The build scrubs Homebrew toolchain overrides; rebuild with adapters/mednafen/build.sh.
• Flycast paces on a host clock over generated audio samples instead of the audio device, so
  pacing no longer depends on an audio backend. Frame steps park at the reported vblank and a
  pause from a running guest parks at the current vblank; both previously ran one more frame.
  Rebuild with adapters/flycast/build.sh.
• Adapter builds run their git commands without fsmonitor, whose daemons held the build lock.
• Dolphin requires host API 7; a budget-stopped advance reports reason: "host_deadline" instead
  of deadline. Dolphin builds configure from a fresh CMake cache with the bundled fmt.
• DeSmuME paces at the DS refresh rate instead of a fixed 60 frames per second and builds
  optimized; a frame step that spends its host budget returns interrupted with
  reason: "host_deadline" instead of an error. Rebuild with adapters/desmume-nds/build.sh.
• PCSX2 requires host API 7; a budget-stopped frame advance reports reason: "host_deadline", and
  a launch whose PINE socket path exceeds the Unix socket limit is refused with that reason.
• PPSSPP headless debugger sessions are now paced at 100 percent instead of running unthrottled;
  set unlimited for the former behavior. Rebuild with adapters/ppsspp/build.sh.
• Mupen64Plus requires host API 6 (core patches through 0007); a pause or speed change no longer waits out a
  slow limiter sleep, and a budget-stopped frame step returns interrupted with
  reason: "host_deadline" instead of an error. Rebuild with adapters/mupen64plus/build.sh.

Validation scope

• Batch reads and pacing are implemented across the advertised adapters. Runtime checks cover
  selected games and profiles; exhaustive fault, output and platform qualification continues.
  Further snapshot presentation-history work, including Mednafen integration, remains open.

Fixed

• N64 native snapshots preserve interrupt-jitter state. Native M64P file loads validate and retain
  their input before releasing the frozen guest, so rejected inputs preserve RAM and registers.
  Legacy snapshots lack the historical jitter sequence; PJ64 and slot imports retain their
  existing behavior. Rebuild the maintained Mupen64Plus host and bridge together.
• Native pacing anchors reset after actual debugger/frame parks, preserving the first resumed
  interval at low speed. Repairs cover MAME, DeSmuME, Mupen64Plus, Mednafen and Flycast.
• Pacing requests reject concurrent operations before waiting on the session lock. Native pacing
  mutation failures close unverified control sessions while preserving the last confirmed policy.
• DeSmuME, PCSX2 and PPSSPP memory batches use one native acquisition per request.
• PPSSPP reports network-governed pacing before local limiter settings.
• Flycast loads a saved state deterministically. A frozen stop now parks at the end of the SH4
  timeslice instead of inside the vblank scheduler callback, where a load let the scheduler finish
  the tick with the pre-load timeline; the same state gave different guest memory and input
  outcomes from run to run. A state saved by an earlier build, which lacks the pending scanline
  event, gets it rescheduled from the restored video state on load. Rebuild with
  adapters/flycast/build.sh.
• MAME Neo Geo CD (neogeo_cd) supports native save_state/load_state and therefore probe.
  Shared MAME patch 0008 registers the CD controller state, marks CDZ save-capable and keeps the
  Neo Geo post-load hook off the audio ROM bank the CD models lack. Rebuild MAME with
  adapters/mame-neogeo/build.sh and adapters/mame-pc98/build.sh.
• WonderSwan status lists its input buttons (X1–X4, Y1–Y4, A, B, Start); it previously offered
  none although set_input accepted them. Rebuild Control and reconnect.
