Hey this BrMSX seems to be good. :-) Hmm... Maybe I should try it someday.

Ok, don't get me wrong... My goal is not to make proggrams, that are not
usabble in emulators. This thing I said was just speculation of my mind.
Anyway one thing, that I don't belive, that Any MSX2 emulator has is a
correct VDP speed... So if we make a proggram, that waits lineinterrupt,
starts a massive copy, waits few scanning lines and terminates copy
operation before it was completed and then calculates, how much it copyed
then... I bet there is no emulator, that can make this right.
(Hey I have only once heard about software, that changed color of box
before it was completely drawn. So maybe there is no any need to emulate
that right ?)
