Some cwcheat/gameshark codes not workiing on psx games

[cunhak9]

Ok , i am testing now multidisc games that i made , Final Fantasy 8 SLUS00892 works fine and the cheat codes(gameshark) works ok , but so far i got 2 games that the codes dont work, wing commander 3 SLUS00019 and Vagrant Story SLUS01040 , i select them in the menu and enable cheats but nothing works :mad: , is there more games that also dosent work with the codes?

edit: some codes for Vagrant story works, some dont!
