With this, RoadRiot works, (sound is not nice).
(I didn't know this game, I really don't like it ;)
Build in obsolescence works too (but freezes latter on a black screen).
Some more programs may run better (those with stack problems).
But again, I don't know if the problem is in this part of the code or
somewhere else.
any advise ?
