Pacman

[Kegster]

I'm having trouble setting up Pacman and Ms Pacman as the middle of screen is fuzzy
like a frequency issue. Using super resolutions I'm not sure how to create game specific ini's and
using them. When I try they don't work. If I'm using normal resolutions I can create
those ini's and they seem to have more flexibility for vertical games. I know there are compromises
when playing vertical games on a horizontal monitor but the results I'm getting are unplayable.

I'm using an 6450 card on a Kortec multi-sync monitor
My log is attached

Thanks

Playing vertical games on CRT is always best on a rotated CRT imho. You are very limited with vertical lines on a CRT which makes a vertical game look pretty bad on a horizontal oriented monitor. Mame is trying to scale the game to the pixels it has available (usually 240) which isn't quite enough for properly interpolating the horizontal width (eg 320)

It's true, a vertical game on horizontal monitor isn't the best option...

In my case, for these games than transposed vertical lines exceed 240 narrowly (256 or 288), i prefer configure it for 240 with pixel perfect.

For example por pacman machine.

In /ini/source create pacman.ini file with
  resolution 2560x240
  unevenstretch 0
 
You can adjust vertical position with slider if you prefer top/bottom lines depending on the game.

(*) I'm sure it's possible do the same playing with crt_range but it's more friendly for me this method.
