A simple but inaccurate method is this: PRINT (256-INP(&HFF))*16 It relies on the fact that in page 3 mapper page 0 is selected and most mappers return unused bits as 1. It is inaccurate because it won't work on mappers that don't return all bits (like turbo R's) and because when there is more than one mapper in the system, it shows the size of the largest one.
