If I get that right, you want me to use the same line 
numbers in both versions?

So it is supposed to work on a PAL TV, when ~70 lines 
are just missing?

Hm... in all my (Mega Drive / Super NES) experiences, a 
difference between 50/60 doesn't make any difference, 
neither in sound nor in gameplay. 

That's just for the simple fact, that you normally don't 
know the *other* version and are used to *yours*

My train of thought was like this:

- The manual says do 38 PAL VBLANK lines.
- I wanted to keep 192 visible lines. 
- Now I thought I've to add all the missing scannlines 
to the overscan.

(BTW: Anybody interested in a full PAL res version can 
easily compile one, all you need to do is adjust the 
timer values and the SCREENSTART variable. Most of the  
game runs fine when using the higher PAL resolution, 
it's mainly that the obstacles aren't adjusted to the 
bigger playfield.)

That way the

Ok, that can be easily adjusted. 
What's with the 262 lines PAL BIN? Would it be centered?
