Well, I most likely won't buy all of them, I'm no Donald Trump.
The games listed as bought are still under way to me, with the exception of Virtual-On and De La Jet Set Radio. Obviously I haven't tested these "bought" games with VGA yet.
Anyway, does anyone have any experience with these games and their VGA-compatibilityness (not even a real word, I know)?
