feat(platforms): add launcher controls for MiSTer, Batocera and ReplayOS - #1680
Conversation
Add controls for MiSTer and MiSTeX cores (menu, reset, save/load state, stop), Batocera via hotkeygen, and ReplayOS via its net control API. Save states take an optional slot argument. RetroArch and Kodi gain pause and resume. Games started outside Zaparoo on MiSTer, Batocera and ReplayOS now report their launcher and controls.

Explanation
Issue
#544requires MiSTer controls for save state, load state, persistent RAM save, reset, and menu toggle when supported. The reviewed MiSTer implementation adds save/load state, reset, menu toggle, and stop.coreControls.controls()inpkg/platforms/mister/controls.gohas no persistent RAM save control. The code and tests cover savestate capability checks, slot validation, and clear unavailable errors, but they do not implement or establish the required persistent RAM action.Resolution
Add the MiSTer persistent RAM save control with capability-aware advertisement and clear failure behavior, and add automated tests for supported and unsupported cores. If MiSTer has no supported persistent RAM action, document and encode that unsupported result in the capability behavior instead of omitting the requirement silently.

Explanation
Issue
#544identifies MiSTer support as its remaining scope. The pull request also adds substantial launcher-control implementations for Batocera and ReplayOS, plus pause/resume behavior for RetroArch and Kodi. These changes are not needed to implement MiSTer controls and are not supporting tests, refactoring, or documentation for that issue.Resolution
Move the Batocera, ReplayOS, RetroArch, and Kodi feature changes to separate linked issues or pull requests, or provide direct linked-issue scope that requires them.

Review comments at @pkg/platforms/batocera/controls.go:
- Around line 55-56: Update the fast-forward mapping in the Batocera control
definitions so it works with RetroArch hold bindings: use a toggle binding, or
provide a separate key-down/key-up control path that holds the mapped keys until
release. Keep the rewind mapping unchanged.
Review comments at @pkg/platforms/mister/controls.go:
- Line 88: Update Platform.StopActiveLauncher to return the error from
ReturnToMenu when no process is tracked, rather than logging it and returning
nil, so the stop control propagates failure to reach the menu.
Review comments at @pkg/platforms/replayos/tracker.go:
- Around line 461-463: Update checkAndUpdateRunningGame to reconcile launcher
metadata when pendingROMPath arrives after the core is already active. Refresh
the current active media’s LauncherID and LauncherControls from
systemInfoFromROMPath instead of returning unchanged metadata solely because the
core did not change.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Return an error when stop cannot reach the menu.
If no process is tracked, Platform.StopActiveLauncher calls ReturnToMenu but logs its error and returns nil. This new stop control consequently reports success even when the core remains open. Propagate that failure from StopActiveLauncher so the control reports the actual result.
