Does BOOM have high resolution (640×480, etc.) video settings?
No, that didn’t make it into Phase I. We were concerned about just turning on other resolutions without proper scaling of menus, status bar, etc. and so chose to defer that to Phase II when we’d have time to do it right. *NEW* There is now high resolution available in the Windows port of BOOM called PRBoom. See the GoGetIt page for download info.
