Windows 7 interlace resolutions
« 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.
Hantarex Polo 15KHz
Sapphire Radeon HD 7750 2GB (GCN)
GroovyMAME 0.197.017h_d3d9ex
CRT Emudriver & CRT Tools 2.0 beta 13 (Crimson 16.2.1 for GCN cards)
Windows 7 Home Premium 64-bit
Intel Core i7-4790K @ 4.8GHz

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.
Important note: posts reporting GM issues without a log will be IGNORED.
Steps to create a log:
 - From command line, run: groovymame.exe -v romname >romname.txt
 - Attach resulting romname.txt file to your post, instead or pasting it.
