Chicken&Dumplings

Hi all - Is there a way in which the screen size can be changed? I've got the shining force games downloaded and trying to run through Teknoparrot (and GLARH v3.6.7) on my arcade cabinet with a windows 7 pc using a CRT monitor (800x600). The games will load in which I can see the intro and get to the menu to read the iccard (f2), from there I cannot progress because I think any menu button I need to press in order to progress is offscreen. I can cliick the ic setup button, but looks like the only i might be able to do is copy my iccard? Overall, I see about 75% of the screen (can see some of the timer at top and 'elect' in the top left corner). There are some settings in GLARH in which it does change the screen display but it also messes up the cursor to where the mouse click appears. Has anyone had success with resizing this game and if so, what settings or files did you have to update? Thanks!
