Problem with s40 games

I've downloaded some java-games for my nokia 6230i, and everything works fine, except the fact that the games don't cover most of the screen. The game screen is much smaller than the phone's screen, and the game goes to the upper-left corner of the phone screen. I don't think I can explain it any better. Does anyone know how to help?

This just happens with these phones.
The games are made to user certain pixels, and There is much more on the newer phones, so its the way they come out!

My nokia 6230i does it too, and i dont think there is anything to do about it.
