This scrub is why Brawl ran in slow motion and included random tripping because the 5 melee players scared him with enjoyable competitive gameplay.
It's probably because they didn't want to pay Dolby licensing fees, not because it makes a 2 second difference in the loading screen.
~~even see how this would affect the loading screen considering I run live AC3 encoding on an old laptop much older than the switch and it has zero effect on the boot and login time.~~ nvm it was a GC game.
Basically every Wii game shipped with Dolby Digital no issue.
