The problem was related to some video timings, but it's not that easy to 
fix at the moment, because it requires 2 cycle precision in the CPU 
emulation (and all cycles are rounded to 4 for now, because it's the 
most common case in STF/STE).

I added a temporary hack, so the demo will run at least, but it should 
be reworked with a complete new cpu emulation after 1.8 is released.
