IBM PC's. My question is therefore is this practical
or even feasible? My guess is it's possible, but some
code could be so convoluted that it would be extremely
difficult. In essence the software would need enough
intelligence to reverse engineer another bunch of
code.
Could it be done totally by automation...
You could take the approach of the Atari Portfolio. Provide some RAM
at the expected video memory address for the application to fiddle
with. Then periodically scan that RAM and copy whatever is there
to the screen.
No, it didn't work terribly well with the Portfolio, but it did
help a bit.
