#1 Incompatibilities with GDK found

[Cinek]

In my opinion GDK uses the register lcd-control
(LCDC) in a strange way.
Well, but I have to admit, too, that I have some
timing problems with the CPU.
The problem is: I don't know the exact "tick-counts"
for each opcode in certain situations.
I figured out that the register LCDC is handled not
correctly in my emulator, but implemented in the
way it is, it plays more games than when I would
fix it for GDK.
This is a difficult situation and I have to learn
more about this bug first.
