could you help me

well my psx works great is there a way to make the screen smaller and not full screen plz help

Hiya, you're obviously referring to an emulator, anyway to change the size of the screen, go to Config > Video > Configure (Button which should appear on video plugin small window) and then according to the plugin you have you should be able to change screen size and resolution on the window which appears. One or two plugins don't allow you to configure, give it a go and come back to me!

Crazy!

He is probably talking about the emulator pSX, which doesn't use plugins.
There should be somehing within the options which will let you play it from a window.
And please use a descriptive thread title next time...

With pSX you can adjust the screen size as you wish without even clicking on anything. The pSX has a stretch screen feature built into it so i doubt he is reffering to pSX.
