Basic CRT EMU driver questions
Calamity:
After looking through your logs everything seems fine but for the -video ddraw, that could be the problem, try changing it to -video d3d if using "magic" resolutions.
You need to add the same monitor_specs line to VMMaker.ini and to mame.ini, otherwise GM won't follow. There's a slight difference in syntax, check this thread: http://forum.arcadecontrols.com/index.php?topic=116023.0
Unfortunately, the lower vertical refresh limit doesn't work very well and can be underflowed when the horizontal frequency is forced to keep below its max value (15800). This happens because the horizontal frequency value (= monitor-breaker value) check has higher priority. This is a flaw in the modeline generator I'm aware of, I'll try to fix it at some point.
Tatas:
Interesting. I have a sneaking suspicion that I don't have a mame.ini file. I know I haven't created one from the command line. Also, would I be hurting myself if I haven't installed directx yet? I don't think I did that when I built this XP x64 build. Could that be affecting the ddraw?
Tatas:
OK, I was correct. I was not using a Mame.ini file. I have used the switch -createconfig with groovymame and I now have one. I also installed DirectX just in case it was needed. I've attached the VMMaker.ini and Mame.ini files that I'm using. I switched to d3d for -video and I think I have the monitor_specs variables set correctly. For some reason things still aren't working. I'm trying to use the magic resolutions approach, but a lot of games are still having issues with the flipping screen. I've attached two zip files, one testing with NTSC as the mode, and one testing with CUSTOM/GENERIC). They also contain a txt output file for two games, one for Mortal Kombat which does not flip in NTSC mode, but does with CUSTOM. The other game is Killer Instinct, which is still flipping the picture with either mode. Any ideas? Sorry to be such a pain on this, I just would really like to have things looking good and I'm sure your program can do that. Unfortunately I've got a party coming up soon that I was hoping to have the cabinet working for. Could you show me how to remove a few of the extra modes that cause Hyperspin not to launch when using the default CRTEMU driver method(120+ modes) as a last resort? I'd at least like to have most of the games working well until I can figure out the "Magic" modes. Thanks again
Calamity:
It's definitely odd because the only mode which doesn't flip is mk with hfreq of 15.2 KHz, everything with a higher hfreq flips... can you check this with Arcade_OSD?
You would need to use a line like this:
monitor_specs0 15200-15500, 49-65.00, 2.000, 4.700, 8.000, 0.064, 0.160, 1.056, 0, 0, 288, 448
And keep lowering the 15500 value until it gets fixed.
Anyway if that's the issue I don't undestand why it should work with the normal approach (120 modelines). In order to reduce the number of modelines, edit the TotalModes option in vmmaker.ini with a value of 80-90 and recalculate the modelines. Find the figure that keeps HS working in your system.
Tatas:
Thanks a ton Calamity. I'll try that. When using the magic modes. I see that in the Arcade OSD, most modes are set as Native, but there are around 4 or 5 maybe that are custom. Most of them display ok, but a few do flip. I will post back with the results. Thanks.
