Help with Hantarex Polo/2 Star
Calamity:
All right, then you've got a Polostar, and you can safely use the 'pstar' settings. Forget about the 800x600 mode, it won't work although advertised.
Edit vmmaker.ini, set MonitorType = "CUSTOM", set ModeTableMethod_XML = 2, and add these custom specs:
monitor_specs0 15700-15800, 45-80, 4.000, 4.700, 5.300, 0.062, 0.062, 0.740, 0, 0, 288, 448
monitor_specs1 16100-16200, 45-80, 1.280, 4.500, 6.420, 0.062, 0.062, 0.740, 0, 0, 288, 448
monitor_specs2 25100-25200, 45-80, 0.200, 0.400, 8.000, 0.040, 0.040, 0.640, 0, 0, 384, 768
monitor_specs3 31500-31600, 45-80, 0.170, 0.350, 5.500, 0.040, 0.040, 0.640, 0, 0, 576, 800
Then create the modes again (run vmmaker + restart). Now set the monitor option in mame.ini to 'pstar', and run GM.
Your modes might be still not properly centered in all ranges anyway, because each monitor can have slightly different adjustments internally.

You're the man calamity ;D I've set the vmmaker.ini and the mame.ini like you said and restarted, when the system booted the resolution was already nice! 640x480 30khz :applaud:
Now I think I have to adjust the values that you gave me because the picture is almost always offcentered, in the vertical games the picture is great and centered but in the horizontal ones the pictures is always to the right, witch value I have to change?
specs0 is for 15khz games, specs1 to 16khz, specs2 to 25khz and specs3 to 31khz, right?
Thank you a lot :notworthy:
Here are some screens of the result:

Calamity:
You have basically two options:
- Option 1: adjust by hardware. The Polostar allows adjusting the horizontal phase of each range individually. On your monitor's chasis, find the East-West board, and on it, the RV1 pot. This will allow you to center the 15 KHz range on the horizontal, while leaving the others (25, 31 kHz) unmodified.
- Option 2 (recommended): adjust by software. Edit mame.ini, set the 'monitor' option to 'custom', and edit these lines:
crt_range0 15700-15800, 50-65, 1.800, 0.400, 7.400, 0.064, 0.160, 1.056, 0, 0, 192, 256, 0, 0
crt_range1 16200-16300, 50-65, 0.200, 0.400, 8.000, 0.040, 0.040, 0.640, 0, 0, 256, 264, 512, 528
crt_range2 25300-25400, 50-65, 0.200, 0.400, 8.000, 0.040, 0.040, 0.640, 0, 0, 384, 400, 768, 800
crt_range3 31500-31600, 50-65, 0.170, 0.350, 5.500, 0.040, 0.040, 0.640, 0, 0, 400, 512, 0, 0
Now, the values in black, are the ones that you need to tweak in order to center the 15 kHz range. To shift it to the left, you need to increase the first one and decrease the second, e.g. 3.800, 0.400, 5.400.
You don't need to mess with VMMaker anymore, this is just a matter of editing mame.ini and launching games to try.

Hi calamity, i managed to center the picture on the screen! Thanks a lot! Now i've got to find a place to fix the black bars on the left side of the screen ;D Strange that they are larger when the resolution is lower ???
By the way, I noticed that the picture doesn't fill the screen vertically, is there a way to fix it or is the picture ratio?

Hi cloaknite, I recommend you to ask the experts on the Monitor/Video subforum, this looks like an electronic problem.

This question is asked every day (literally), so I already have a template answer:
- GM can make all your resolutions to almost fit perfectly on the HORIZONTAL, once you find your custom specs.
- No software can control the VERTICAL size of a resolution on a CRT monitor, you need to adjust it physically (potentiometers, service menu, etc.).
I'm thinking I should probably copy this to the main GM's thread :)
