Title: Vertical games on horizontal monitor at their native res
Post by: donluca on February 04, 2016, 03:55:06 pm

Simply put: if I have a monitor like a Nanao MS9 which supports 24Khz, can I use it to play vertical games at their native resolution and refresh without rotating the monitor?

The idea is to use the higher resolution offered by 24Khz monitors (512x384, I believe) to play vertical games at their native resolution (for example 320x240) and refresh without rotating the monitor (by playing them at something like 512x320 with black borders on left and right)

Is it possible with VMMaker to achieve this?

also interested to know this  :lol , I have the option of a POLO 15/25AUTO , maybe it's a better choice than a 15khz-only POLO?

Bumping in the hope that Calamity-senpai notices this. :P

Sure, just make sure to adjust the lower progressive line limit:

      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, 320, 400, 0, 0

You'll need VMMaker 2.0 to use these settings.

I'm intrigued by this.
My monitor is capable of 25kHz provided I move a jumper over on my chassis, it doesn't auto switch. Can I use similar setting to the one's you've mentioned above Calamity? Up until now I've only been stuffing around with 15kHz but like the idea of running the higher res vertical games at native resolutions on my horizontal screen. Also what would this do to my 15 kHz horizontal games and those vertical games up to 256 lines?

EDIT: From what I can gather, if my monitor were set to 25kHz it wouldn't be able to display 15kHz games as the scan rate would be too high.

Please remind me... is VMMaker 2.0 compatible with Windows XP 32bit? And is it compatible with the old CRT Emudrivers? (I have an X300SE)

My current setup is GM 0.167 (iirc, it might be 0.166), CRT Emudriver 1.2b and the latest pre-2.0 VMMaker available.

Also, does GM automatically pick the correct resolution or do I have to create custom .ini to tell GM to run vertical games with 512x320 res?

- The standalone CRT Tools package may be used with previous versions of CRT Emudriver, both for Windows XP and Windows 7/8. Just make sure to generate a fresh video mode list using the new tools.

GM picks the resolution automatically if you create the correct preset.
