Personally, I'm not sure why you wouldn't want the timestamps on auto-saved replays, but one solution that could allow the option to still work would be to append a number if the replay already exists, e.g. if replay.nxrb exists, save the file as replay_2.nxrb, then replay_3.nxrb, etc. I don't know how manually saving them works anymore due to using the auto-saving, but if it's automatically choosing the save location and filename instead of prompting the user with a system dialogue box, this might still be a good idea to prevent accidental replay overwriting.
