Asserter was renamed to TestWrangler and gained a new start method. This is done automatically by default,
but in games where preparing the game state exceeds the startup schedule this could cause problems. If you want to
start playback / recording manually, set PlaybackTestingOptions::manual_start to true and call
TestWrangler::start when the game is ready. This function is idempotent so you can safely call it multiple
times.
Fixed several bugs, including not sending gamepad events on playback, which made certain setups not work.
Look at the examples and try your best.
