I just checked some names against scene releases and I think some names here are wrong/uncompleted:

I've taken a look at the games. The Korean one I have no idea; I don't speak, read or write Korean. As for the others:

http://redump.org/disc/17877/
The title on PSP cover is NBA as can be seen here: https://gamefaqs.akamaized.net/box/7/3/ … _front.jpg
So, no change necessary.

http://redump.org/disc/30810/
The US title has no 'Split/Second' subtitle as can be seen here: https://gamefaqs.akamaized.net/box/8/8/ … _front.jpg
And for reference a Europe cover: https://gamefaqs.akamaized.net/box/8/8/ … _front.jpg
So, no change necessary.

http://redump.org/disc/4682/
The cover indeed has 'Sudoku Battle Action' on there as can be seen here: https://gamefaqs.akamaized.net/box/8/1/ … _front.jpg

But I'm not sure if it's actually part of the title or just some description or 'genre' of the game. Most websites like Wikipedia, Gamefaqs, webshops etc. all just call it 'Zendoku'. So, change maybe necessary, but in my opinion it should stay Zendoku.

EDIT: the title on the spine is just 'Zendoku' so I think it's pretty clear now the title should not be changed.

In Japan the game is called Tenchu 4, but in Europe/USA the four is swapped for the subtitle 'Shadow Assassins' as can be seen here: https://gamefaqs.gamespot.com/psp/95515 … ins/images
So, no change necessary.

The Korean title for that game as listed on the official Korean PlayStation website is 삐뽀사루 겟츄P!, which only differs in spacing and punctuation from what's on Redump. The straightforward romanization is Ppipposaru Getchyu P!, but if you want to match other discs like http://redump.org/disc/4563/, it should be something like Ppipposaru! Get You! P!
