Title: Super resolution - Galaga/Pacman modeline on horizontale CRT @60hz
Post by: dirtybb on April 15, 2016, 11:01:15 am

Hi,

I would like to have your opinions and advices about that,

What is the best modeline (super resolution) that i can use in order to play Puckman or Galaga @60HZ and that offer the best "video feeling" on an Horizontal CRT (NAC MS9-29) ?

In other word, what is for you the best compromise ?

Cheers, Dirtybb

In my experience, interlaced modes in the 24 kHz range look really nice. So if you're not allergic to interlace, you can use 2560x768i or even 2560x800i.

Notice that the ms929 preset won't do interlaced modes in the 24 kHz range by default. You'll need to redefine it like this (both in VMMaker 2.0 and GroovyMAME):


      crt_range0  15450-16050, 50-65, 3.910, 4.700, 6.850, 0.190, 0.191, 1.018, 0, 0, 192, 288, 448, 576
      crt_range1  23900-24900, 50-65, 2.910, 3.000, 4.440, 0.451, 0.164, 1.048, 0, 0, 384, 400, 768, 480
