Problem with SDL games

Hi!

I have problem with running SDL games written for BeOS (i.e. kobodeluxe, wolf3d or rocks’n’diamonds). They work only if are executed from terminal, otherwise they’re instantly exiting. There is workaround for this problem - writing shell script which executes game from it’s directory, for example:

cd /boot/apps/Wolf3d
sdlwolf3d

But is it possible to run these games without ugly terminal window?

Thanks in advance
