True, but normally if it doesn't playback for an editor, it will also NOT playback for a very large portion of other marpers if the record settings are stated improperly. And, of course if it is said to playback by the recorder themself and this recording doesn't playback by anyone else, it effectivly does NOT playback.(posted 9009 days ago)Unfortunatley there are some games that "sometimes" playback based on which millisecond random seed you start the playback on. These are nigthmareish because sometimes the recorder (me a long time ago with flipshot) could play back the recording twice once right after the other but never be able to play it back again after dozens of trys. These recordings will also get nuked from marp, since a recording that works once in a 1000 playbacks shouldn't be archived. People (me and my beloved flipshot) will just have to consumate the patience to wait for mame -playback to work with that game and then record again with much improved skills.
Also if it doesn't playback for a "confirmer", the score will just stay unconfirmed for someone else to confirm it with the right guessed settings.
