"RetroArch" matching MCP tools:
- Reads RetroArch emulator status: playing/paused state, loaded system, game basename, and CRC32. Required before toggling pause or frame advance to verify current state.MIT
- Retrieve a single RetroArch configuration value by parameter name via the Network Control Interface to access filesystem paths and settings without manually parsing the config file.MIT
- Display a single-line notification overlaid on the RetroArch window for debug output, progress markers, or user alerts. The message fades out after the configured timeout.MIT
- Restore the emulator to its previously saved state by loading from the currently selected save slot. Undo changes and revert to a known baseline.MIT
- Load a save state from a numbered slot without altering RetroArch's current-slot pointer. Use to access specific bookmarks while preserving ongoing save location.MIT
- Decrement the current RetroArch save slot by 1. Use before saving or loading to target a lower-numbered slot.MIT
- Read up to 4096 bytes from the libretro core's system memory map and return them as a hex dump. Use when the loaded core advertises a memory map.MIT
- Read up to 4096 bytes from emulated memory using the CHEEVOS address space, returning a hex dump. Use as fallback when the core lacks a memory map.MIT
- Increment RetroArch's current save slot pointer by one, enabling targeted state save and load operations.MIT
- Write byte sequences to emulated game memory via the libretro core's memory map for cheats, debug pokes, and state mutations. Returns the number of bytes actually written.MIT
- Write byte sequence to emulated memory via CHEEVOS address space. Fallback when core lacks memory map. Verify changes with read.MIT
- Toggle RetroArch's pause state to pause if running or unpause if paused. Use retroarch_get_status to confirm current state before toggling.MIT
- Step emulation forward one frame at a time while paused. Use for precise input timing, animation inspection, or letting emulation initialize after a reset.MIT
- Trigger a soft reset of the running game, equivalent to pressing the console's reset button, to restart from the reset vector. Unsaved progress is lost.MIT
- Save the emulator state to RetroArch's currently selected save slot for creating rollback points or bookmarking game states.MIT
- Capture a PNG screenshot of the current emulator display and save it to RetroArch's configured screenshot directory. Use to verify game state or inspect visible effects of control commands.MIT
