No, restart your game.
Try using homebrew to write another save file (find another main file around the net), then you should be able to get to the continue screen.
You're best off restarting, something got corrupted (likely on transferring).
PKHeX recognizes unreadable pk6 files inside the save, so you're best off dumping the undamaged pkm's and restarting.
Their portraits are affectionately referred to as 'mugshots'
a/1/6/0 - trainer mugshots
You can unpack the GARC with pk3DS and can use png2bclim to convert then between formats (or just use pk3DS for that too).
Adding/Removing items does not alter any ingame flags. Those flags are currently un-researched.
It's still best to progress the story to get the relevant items naturally.
You'd have to unpack the narc if you wanted to see individual script files.
I'm pretty sure SDSME has a script editor in which you can just goto the end of the script list...
Depends what actually is corrupted; if you saved a backup (probably not) you can compare files.
It's quite likely that whatever method of writing it back to the save failed; if you transferred it via ftp you might have had some communication issues.
Boxes can be dumped via the Tools dropdown.
It's related to the new legality checks, will fix tonight as I know the cause(s).
Thanks for the test cases, they will be helpful.
edit: fixed, ty for the report

You would have to look at the individual script that the overworld file assigns to that entity. If I had to guess, it'd be a callstd or another nonstandard wild encounter script in another script file.
The problem is that you are trying to trade them online.
Read the stickies of this subforum and of the site; we do not offer assistance on how to cheat online, which includes trading hacks or battling with them.
Read the changelog in the OP.
Ram2sav is no longer supported (you should be using homebrew), and save exporting has been moved to the main ribbon at the top via File.
