besides, i found following issue. please confirm.

1. Description "in / on" were not same.
   "Shows the game you are currently playing as part of your profile in Discord." common interface description for discord.
   "Shows the game you are currently playing as part of your profile on Discord." in "Big Picture" mode description for discord.

2. Crash occurs when changing language under "Big Picture" mode.

3. please add following string for "Big picture" mode, "Widescreen Hack, Multitap, Audio Control, Configuration, General, System, Graphics, Audio, Save States"

4. open rewinds will cause "big picture" mode halted, especially can't access "setting".

5. switch the multitap will cause halted when the game is running.

6. some one told me he found a bug. his original text as follow.
   "Hello, can you reflect a BUG in duckstation to the author? That is, if you use the button of the handle to use the rewind function, as long as you press it, it will keep rewinding and cannot be canceled. (under normal circumstances, long press the button to rewind the tape, and it will be normal after releasing); If the rewind shortcut key is bound into the keyboard, then the rewind function is normal, it is strange, the handle key rewind will go wrong."

Not sure how you managed to rewrite the entire qttranslations.cpp file, maybe line endings. I cherry-picked the ts update in 23356fad452a1fa33cc6dcf2fc0fee6e1f97bcff.

Missing strings and crash on rewind enable should be fixed, I'll look at the others when I have time.
