Monitor presets
elvis:
Did some testing tonight on my Chinese knockoff cabinet "Megalo City 29":
https://wiki.arcadeotaku.com/w/Sega_Megalo_City_29
No idea what the CRT or chassis is. Tube is made in Mexico, chasis has "Model-988" printed on it, but no other useful branding.
arcade_15 caused convergence issues along the top half-inch of the screen. Reducing the VSyncPulse down fixed that, and my final working mode across as many ~15KHz 4:3 horizontal games as I could test in GroovyArcade 2018:
crt_range0 15625-15750, 49.50-65.00, 2.000, 4.700, 8.000, 0.064, 0.142, 0.324, 0, 0, 192, 288, 448, 576

Bonjour à tous! :-)
First I'm french so excuse my poor english level... :P
Second I would like to know if my emulation system is 100% optimized to run my Groovymame (0.158), CRT Emudriver (9.5) and Switchres on my PAL TV.
So here is my devices:
Mame 0.158
Windows XP Pro 64 bits
Micro atx Gigabyte mother board
Intel Xeon X3380 CPU
4 Go ddr2
Ati radeon X1050 GPU
To match with my french PAL TV I've set these monitor presets:
GroovyMAME format: crt_range0 15625-15750, 49.50-65.00, 2.000, 4.700, 8.000, 0.064, 0.192, 1.024, 0, 0, 192, 288, 448, 576
VMMaker format: monitor_specs0 15625-15750, 49.50-65.00, 2.000, 4.700, 8.000, 0.064, 0.192, 1.024, 0, 0, 288, 448
Is it the preset for my PAL TV and I would like to know which preset I must use for my Sony PVM 2950?
Thank you for your help! ^_^

Sega Astro City w/ MS9 chassis, is it better to run this preset or just Arcade Monitor 15khz preset?

Dracrius:
Could I use the info from this Timing Calculator to make a preset? I tried setting the calculator to "VESA 1600x1200" and it has all the values I'd need but they are represented as pixel counts not microseconds.
I ask because I tried editing the VESA 768 preset but every resolution from VESA is very distorted. So rather then having to adjust a single resolutions (with Arcade 31) I'd have to adjust EVERY resolution with my monitors OSD if I use a VESA preset. I'd rather understand how to make a proper preset for my monitor. Unfortunately I can not find an online copy of the manual or Timing chart for my monitor as that seems to be the easiest way to get the needed information.
When I tried to edit the Arcade 31 preset it would break and not generate any modelines at all when I hit generate.
I'm trying to make 480 my lowest so 240 plays at 480 and 768 as my max with 384 games being displayed at 768.
This is what I tried to do to Arcade 31 and idk why it didnt work. I went back to edit Arcade 31 because its modelines match my monitor. All except 384 but I'd rather those games played at 768 anyways. I am trying to double resolutions so that when I add scanlines they go over those duplicate lines. I'm guessing I will still have to adjust the 768 res if I can get it to be used but adjusting one resolution is no big deal.
--- Code: ---monitor "arcade_31", "Arcade 31.5 kHz - high resolution", "4:3"
crt_range0 31400-31500, 49.50-65.00, 0.940, 3.770, 1.890, 0.349, 0.064, 1.017, 0, 0, 480, 768, 0, 0
--- End code ---
Dracrius:
Figured out why the Arcade 31 Preset wouldn't accept resolutions higher then 512. It was one or both of the sync frequency's. I adjusted both the maximums to match my monitor as I can at least deduce those from the information I have. My new Arcade 31 Preset is as follows.
--- Code: ---monitor "arcade_31", "Arcade 31.5 kHz - high resolution", "4:3"
crt_range0 31400-93750, 49.50-75.00, 0.940, 3.770, 1.890, 0.349, 0.064, 1.017, 0, 0, 480, 1200, 0, 0
--- End code ---
Since there is no 1600x1200 modeline that last resolution never gets made but the stock 1600x1200 is maintained so I'm not to worried. NVM it appears to generate missing modelines its way off unlike all the other resolutions though. I reduced it to 960 until I learn to edit modelines as vector games appear to use the highest res in the list unless I'm mistaken!
