not the correct resolution for 448x224 games

[OlDirty]

I just set up my system with an Egret 2 (Nanao MS9 chassis) in vertical position. I use that just for vertical games such as shmups. Problem is, that a few cave games are running in the wrong resolution (see pics).
Instead of 448x224 they are running in 512x448i.

I tried "vertical" "rotation_l" and "rotation_r" in the Mame.ini but the resolution stayed the same.

So i played a bit with VMMaker, but i'm not sure what to choose on the "Settings" page. Could someone give me an advice. Thanks

Is it possible to rotate the windows desktop or can't groovy mame cope with that? I read once that groovy mame doesn't like it when the desktop is rotated. But maybe that was in the past.

You don't have a 448x224 mode. Either add it to the modelist in VMMaker, or better, go the super resolution route.

I tried to use super resolutions with this guide http://geedorah.com/eiusdemmodi/forum/viewtopic.php?id=301

Unfortunately the picture is squeezed for all the games now  . Something what is not clear to me.

Then, in the MAME tab, I'm only going to browse to my GroovyMAME folder, but I won't be listing modes from XML by now. What I'll do is to check "Export settings to GroovyMAME", so future monitor settings will be synchronized with VMMaker.

Do i have to browse in the MAME tab to the Mame64.exe and also check "Export settings to GroovyMAME"??


EDIT: I selected "desktop rotates too" even my desktop was still horizontal  . This caused the games to bee to narrow. Problem solved and also ESPGaluda seem to run now in the correct resolution.  Sorry for all that..

Try forcing -aspect 3:4 in mame.ini.
