I agree it's a hell-of-a job, but why not treat it the same way as the
problem of programs not allocating CHIP memory correctly ( you remember,
back in the old days when 512K was alot :-) of memory ). Wouldn't it
be possible to have a program that worked the same way ATOM worked with
the conversion to fast memory? And if the programs still don't work,
tough!!!! If the companies that wrote them aren't far-sighted enough
( actually, if they are just not-near-sighted :-) they should be looking
out for something like that ...
Of course, it's the customer that suffers, but if someone buys one of these
new machines ( or the new version of AmigaDOS or whatever it takes ) they
will have to be aware of the fact that some of their older programs
might not work.
I mean, hell, I still have a 1000 and I'm all for you guys going full
ahead and making these new machines as good as possible. I won't be
buying another machine until it has memory protection anyway ... I'd
really rather it be a 68020/68030 Amiga with lots of amazing (not
necessarily compatible) graphics capabilities ...
