Just started to experiment with running raine (my cab is currently running a super-crappy pII-400

)
I've got "arcade monitor mode" to work - . . .
except the top two inches of the screen sort of "fold over" to the right, sort of leaning over at about 45 degrees.
The raine.cfg file doesn't have much explanation for the four arcade monitor options that I can find (h timing, v timing, center x and center y), but says that
"Altering these values by any significant amount may lead to damamge to your arcade monitor, and you do so at your own risk", so I don't want to fiddle too much . . .
Any thoughts?
