Title: GroovyArcade & 288 lines with horizontal monitor
Post by: BeeryGaz on December 27, 2013, 05:55:06 am

I'm trying to get 288 line games to display correctly on my horizontal monitor.  I'd prefer not to tweak the h-size POT so I'm happy to go with virtualized resolutions, but I'm not sure how to do this on the Linux version.  re is no vmmaker.ini and no monitor_specs_0 lines in mame.ini so I'm a bit lost (I'm running a radeon X800 with a 15Hz generic monitor).

Hi BeeryGaz,

That's very easy to achieve. Just grab the generic_15 preset from here: http://forum.arcadecontrols.com/index.php/topic,116023.0.html (http://forum.arcadecontrols.com/index.php/topic,116023.0.html)

crt_range0  15625-15750, 49.50-65.00, 2.000, 4.700, 8.000, 0.064, 0.192, 1.024, 0, 0, 192, 288, 448, 576

As you see, it is defined to cover the range from 192 to 288 progressive lines. Just modify it as you like, e.g 192 to 256 lines:

crt_range0  15625-15750, 49.50-65.00, 2.000, 4.700, 8.000, 0.064, 0.192, 1.024, 0, 0, 192, 256, 448, 576

This line goes into mame.ini, obviously. Remind to edit the "monitor" option in mame.ini, to "monitor custom", so that the custom crt_range line has effect.
