Sonic Wings Special does something that have also been found in some other games.

Here the no$psx developer lists it under "Mis-mastered" files https://problemkaputt.de/psxspx-cdrom-file-formats.htm

They stuck video data at the end of the game for padding. Except it's just the data, not a properly arrange video. If you extract the file that it's contained in as "Normal 2048 bytes/sector", then open that file in jPSXdec, it'll be a 2352 bytes/sector disc with a readable video.

Since this happens in a few places, it's something I think would be worth adding direct support for in jPSXdec.
