A larger memory chip ought to work as long as you aren't trying to use the 
additional memory.  One problem is that the additional address line(s) may be 
floating.  If these lines see different logic levels over time it will create 
glitches in the video.  The simple fix for this is to ground the additional 
address line(s).
