Topic: AHK-script to change resolution

Hi guys!

I have installed CRT emudriver on a windows 10 PC with an AMD r7 260X. I run a VGA-cable to an UMSA-converter and SCART to my B&O MX4000 consumer CRT. It's a european model that does both 50 and 60 hz.

I use Retroarch 1.90 with switchres. The later versions have been giving me trouble with audio crackles.

Some times when I have been running a game in a 240p resolution in Retroarch, the resolution doesn't change back to 480i (my desktop resolution) after I quit Retroarch. This happens especially often with the Mupen64-next core.

To solve this I'm trying to use an AHK-script to easily change the resolution back to 480i. However, it's behaving strangely. When I run it while in 576i (PAL-resolution), it changes to 480i with no trouble. But when I run it in while in the super resolution that Mupen64-next leaves after quitting, nothing happens. When i manually switch to a 240p super resolution in windows and try the script, again nothing happens.

My AHK-script looks like this:

r::
ChangeResolution(32,640,480,60)
return

ChangeResolution( cD, sW, sH, rR )
{
    VarSetCapacity(dM,156,0), NumPut(156,2,&dM,36)
    DllCall( "EnumDisplaySettingsA", UInt,0, UInt,-1, UInt,&dM ),
    NumPut(0x5c0000,dM,40)
    NumPut(cD,dM,104), NumPut(sW,dM,108), NumPut(sH,dM,112), NumPut(rR,dM,120)
    Return DllCall( "ChangeDisplaySettingsA", UInt,&dM, UInt,0 )
}

My resolutions for CRT emudriver look like this:

## Desktop ##

320 x 240 @ 60.000000 desktop
640 x 480 @ 60.000000 desktop
640 x 480 @ 30.000000 desktop

2560 x 512 @ 50.000000 retroarch
2560 x 576 @ 50.000000 retroarch

Any idea how I can get the script to change the resolution back to 480i from a 240p super resolution?

Thanks in advance!
