Yes the VGA box works great on dreamcast, but that's because dreamcast was designed to include vga output. PS2 was not, not sure about gamecube, but there is some post saying you can mod a composite cable to run on your monitor. Anyway, a tv card or third party vga box for the ps2 will not look half as good as the dreamcast vga box. Seeing it is your only option to play games in your room, you might have to settle with one of thoes options.
