How to rotate non-MAME emulators using MALA on a cocktail machine

(1/3) > >>

displacedtexan:
I have built myself at MS-Pacman style cocktail and would like to run non-MAME emulators (like fceUltra or Fusion) on it.  Of course I am having difficulty with them using my vertical monitor.

The best video settings for MALA/MAME seem to be a default resolution of 800 x 600 using MALA's rotate feature and MAME's -rol setting.  Everything works fine (most notably horizontal games like Outrun fill up the entire width of the screen).

Unfortunately when I use fecUltra, the screen is rotated 90 degrees. 

But, if I try to rotate the screen using Nvidia's built in tools, everything works fine except black bars appear around all sides (including the left and right side) of horizontal MAME games like Outrun, making the picture really really small.

I know I am not the only person to use MALA/MAME/console emulators on a vertical monitor.  What settings have people successfully used with NVidia's cards?  Specifically, do people use Nvidia's screen rotate, etc?  If so, how what settings (both resolution and mame.ini settings) will allow horizontal MAME games to be displayed properly?

Thanks in advance for the help in making my MAME machine be all that it can be!!

loadman:
Yeah... ;)

I went down that road once and found that a few mame games do not like be rotated by other software ..  :-[

Honest opinon?  Get an ati card with hardware rotation support... every card nvidia has ever made in the history of the company as been crap when you look at visual quality/settings alone.

I don't want to start a flame war, but I have the same feelings when it comes to ATI and linux support.  Now, if your setup is doing exactly what I want mine to do, I may give it a second thought...

Nvidia does have built in HW support for rotation, it's just a matter of getting to it.

I am heading down the right path though.  I have downloaded a program called iRotate at http://www.entechtaiwan.net/util/irotate.shtm which calls my video cards HW rotate function, and can do it via command line... so under MALA's "Other Emu Config" -> "Execution" tab's pre  execution command line I have added the following:

C:\Program Files\iRotate\iRotate.exe /rotate=90

and post execution:

C:\Program Files\iRotate\iRotate.exe /rotate=0

Now I just need to make sure the focus is correct on everything and adjust the emulators screen size to my liking...

Definitely making progress...

Well linux is a poor choice for a mamecab anyway, so linux support isn't an issue.  ;)

Your are on the right track... nvidia's weakest link (amoung an entire chain of weak links) is it's software interface.  I use irotate myself for my ati cards and it works well.
