long time lurker, firstly big shout to Calamity for such a fine project.
After hours of reading got everything set up, Windows, MAME, GroovyMame, mame.ini, CRT Emudriver with VMMAKER pointing to GroovyMame v182
Tested some normal games and problem games, all fine and verified with a good resolution and correct frequency (MK2, Toki, Rtype, Snow Bros, 1942, Galaga, Pacman, Elevator Action, etc) I was surprised at how tolerant my NTSC Trinitron is, accepting Vertical frequencies as low as 54Hz (MK2) with no problems, running nice and smooth.
Examples of 2 good working games.. C:\MAME182>groovymame64.exe mk2
SwitchRes: [mk2] (1) horizontal (400x254@54.706841)->(400x256@54.706841) Average speed: 99.95% (8 seconds)
C:\MAME182>groovymame64.exe rtype
SwitchRes: [rtype] (1) horizontal (384x256@55.017605)->(384x256@55.017605) Average speed: 99.98% (2 seconds)
2 of my non-working games are Xexex (54.253471) and Psychic 5 (53.800000) Xexex gives a stable screen but the image is starting half-way on the screen
(example pic) it doesn't roll. Psychic 5 is not stable, the picture is rolling - likely too low frequency for the TV.
All the non-working games so far are running at low Vertical Hz and I suspect that could be the reason but not sure how to fix it.
I tried changing the frequency range for Generic_15 crt_range0 from 15625-16200 49.50-65.00 to 15625-16200 54.50-65.00 but VMMAKER kept saying there was an error in my setting, so I had to revert it back (error in monitor range, ignoring). I'm stuck at trying to find a solution getting these games working.
A few details..
display: SONY NTSC Trinitron
Windows 7 X64
HD 4600
Groovymame 182 (also tested on version 171)
CRT Emudriver 2.0 and VMMAKER 2.0 beta 9 , monitor mode: Generic_15
I have attached logs of Xexex and Psychic 5, plus some working games and my mame.ini (renamed as mame.txt)
Any help appreciated, pulling my hair out on these last few games.
