Black-screen problem with some games

[Game_Freak]

Hi.
I have some games that i can´t get to work, the screen turns black when they start. I don´t know, but i think it´s either RGB or PAL-fix I need for this games.
I have looked at gamefreax.de and dccopyworld.com, but there was nothing for those games, and yes i have searched in this forum for answers, but I couldn´t find anything.
Please can anyone help me with some place to download, if there is some fixes for those.
Is there anyone else that have the same problem or is it only my DC?
I have a Pal DC, Sony TV that can handle 50/60Hz PAL/NTSC, RGB-Cable

The games is:
Kanon
Jet Coaster Dream
World Neverland
Lets Make A Baseball Team
Climax Landers
NBA 2K
NFL 2K
Golf Shyounyo 2
Card Captor Sakura
Photohunter
Pocke-Kano
Revive
Dinocrisis 2 (Jap)
