I think the LCD's should always display in their native resolution when in fullscreen mode. Much better to let the dosbox code decide the small tweaks as LCD's differ from one to next piece. Demanding the absolutely correct refresh rate emulation is almost "fetishistic". Maybe the right aspect ratio …

Ej, nice work "stari". I'll try to modify the patch when i have time to add some additional features like correct aspect ratio on 1280x1024 LCD's. But maybe you will come ahead of me. "Nadaljuj z dobrim delom".
