can some one please clarify, why this is optional (self choose)?
There are so many Games needing the "Mode 3" to run correctly,
and on the other side so many (if not all) Games that run without Mode 3 also start with Mode 3 enabled.
So wouldn't it be a good thing to make Mode 3 fixed integrated in patched HDL,
and instead have this free space then used by other new yet unreleased patches?
