Anyone knowledgeable on #msx coding ( @reidrac ) know about the VDP acid test?
I find it hard to believe many games conform to this standard - an extra call and return per vdp register write at minimum seems absurd.
There are a couple things like this in the technical handbook that don't appear to have actually been implemented in practice, or abandoned in favor of better code.
Added "supporting" objects with individual gravity, which will be the basis for moving platforms and maybe also lifts. Free bonus iso-sort glitching too.
