Capcom Fighting Collection 2 not working on CRT - Crt Emudriver - How to 640x480

[Sarda]

I have an arcade cabinet where I use a 15khz monitor with Crt Emudriver for years (previously, soft15khz)

I was planning on playing CvS2 Ranked online on it in the new Capcom Classics Collection 2 for Steam but the game will crash everytime at startup if the resolution is below 800x600

I've tried in several different ways, editing the configuration files with no success. Disconnecting the CRT monitor and remote accessing the machine, removing the 15khz resolution and bringing it to higher resolutions remotely will make the game run, but as soon as I save settings and return to 640x480i, it will crash

I tried adding 1280x960 on VMMAKER so that it could boot than use Special K to force a 640x480 resolution but the x960 resolution will not show up due to the VmMaker

I know this is a limitation on Capcom Classics Collection, but running modern CvS2 on the cabinet would be amazing to play ranked online and I'm trying how to solve it

Does anyone have any idea on this? Thank you!
