After a netplay savestate load, the GGRS session's internal frame counter
must be reset to match the savestate's frame, or desync detection fires
immediately on resume.
Changes:
- Patch vendored ggrs 0.13.0 to expose set_current_frame(frame) on
P2PSession and SyncTestSession, with internal SyncLayer and InputQueue
reset methods to clear stale saved states, checksum history, and input
queues
- Add [patch.crates-io] ggrs = { path = 'vendor/ggrs' } in Cargo.toml
- Add netplay::reset_frame(session, frame) wrapper function
- Record current GGRS frame in Savestate.netplay_frame during
create_savestate when in netplay context
- Call reset_frame after load_savestate in netplay context
- Add tests: advance 120 frames, reset to 60, verify current_frame()==60
and clean resume with matching inputs; reset to 0; idempotent reset
