melonRA Changelog:
Linux: Accepting a Netplay invite through Discord without having melonRA open would show an "Unknown protocol" error message, this was because it wasn't registered properly with the rest of apps in the OS, it now handles it properly.
Netplay: Errors whilst syncing up instances and saves with the "hidden consoles" used for Netplay.
Netplay: Closing the room closes the open UDP port after a while.
Netplay: Closing a room with nobody connected is now instant.
Other minor Netplay fixes.
Rewind kept its history after inserting a cartridge or booting up firmware. Meaning that, rewinding could make you rewind to a previous game. This has been patched.
Other general fixes.
Casual mode offline unlocks were dropped if the saved login expired when its sent, now it is kept for the next login. And now the text is clearer when you play offline.
