The one on the left is klonoa 2 lunatea's veil ( realised 2001)
And the one on the right is klonoa door to phantomile  (originally released in 1997 for the ps1 then it was remastered for the Wii in 2008)
I was lucky enough to find these cheep used on Amazon klonoa 2 I got for 18$ a brand new sealed copy can go for 120$ the Wii game I got for 15$ but a brand new one can go for 90$ to 100$
But the original ps1 version can go for 50$ used and a brand new sealed copy can go for ( get this )
350$ to 500$ I'm not kidding....
Thankfully u can buy the original ps1 version on the PS3 for 6$ but they didn't put the ps2 game on the store tho >:(
