Title: Windows 7 interlace resolutions
Post by: Cisek on May 12, 2017, 05:29:48 am

Hi

All my interlaced resolutions works only half speed in Windows 7, I mean in mame everything is ok, but if I load a game or frontend and play it in 640x480 it is playing half seed. Any solutions to this?

What hardware, OS, CRT_EmuDriver version, GroovyMame version, etc...?

Maybe post a log from a game that's showing this issue too.

Radeon 4350 with UMSA, Windows 7, crt emudriver 2.0, groovymame 0.170.
I read that setting positive sync should solve the problem, but how to set it in VMM Maker?

IF it's not GM you can't really post a log, but what's an example of an emulator/game that runs at half speed?

It's done by editing the polarity fields in monitor.ini/mame.ini:

crt_range0 15625-16200, 49.50-65.00, 2.000, 4.700, 8.000, 0.064, 0.192, 1.024, 0, 0, 192, 288, 448, 576

0 means negative, 1 means positive.
