Ok, so this is how I print my covers.
I use MS Paint, do page setup, pick Landscape, Legal size Paper and adjust to 100% normal size.
So far this has worked for over 40 game covers I;ve printed.
But when I do this for contra, it balloons its size and tries to print it in like 4 pages or more.
I tried using irfanview and got the same results.
btw I'm using the Custom NTSC (American) cover version
