So, what you are saying is that the claims in the documentation we got about
the Net Yaroze is wrong when it states we have 2MB of memory to use! Because
of the kernel we only get 1.44MB. The documentation has a FAQ section in
which is effectively asked "What sort of game can I make in 2MB?" and the
answer is effectively "Anything. Ridge Racer, Tomb Raider etc." I think that
is very misleading and should be re-written to say 1.44MB instead of 2 and
that those games spool the level data off the CD and do not keep it all in
memory. Also those games were written with a full development kit which may
give the programmer more memory.
