Oh,. yes, that problem with not enough memory sounds familiar to me, too
I discovered it lately when I tried to run 'Giddy 3', the sequel to the known series of Amiga Dizzy clones. Pity it is a PC version and not an Amiga one....
Fortunately I only owned a C64 & A-500 and no PeeCee until '97, and I think I didn't miss anything.
A 512k ram expansion always did the job for me when having memory problems with Amigagames
