If you play Skullgirls or Rivals of Aether on PC, there’s a good chance you either use (or have heard of) taylorsussex‘s Automatic Replay Viewer. This program allows for sets of consecutive replays to be played back automatically, and can start/stop recording software such as OBS with a hotkey. It does this by simulating the inputs required to playback a specified amount of replays, making it useful for recording long sets without the system strain.
If that sounds good to you and you play BlazBlue:Cross Tag Battle, well…
A new version of AutomaticReplayViewer has been released
BBTag is now supported!
