Hello,
Today I do not use automatic modeline generation from MAME, I set manually a bunch of resolutions in ArcadeOSD.
Because my CRT has a geometric issue on the right side which is compressed
What I do is horizontally stretching the CRT screen to get that part out, then I set the modelines manually in ArcadeOSD to get the games picture well centered back.
I would like to know is this horizontal stretching can be set in monitor.ini config file in "arcade_15ex" for example, or somewhere else
Because when I use the modeline generation of MAME the picture is not centered
Is there a tutorial ?
Thank you !
Fabien

Below is the arcade_15 range line. The bolded values for HFrontPorch, HSyncPulse, HBackPorch respectively, and you can find them in ArcadeOSD when editing. Your values will be different, remember. Copy your values into mame.ini (or into each machine.ini - like neogeo.ini - or game.ini - like sf2.ini - if you need to for each game)
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
You can also set these range options in VMM using the monitor.ini file by adjusting whichever line, like "arcade_15ex" as you note. But this way only fixes things once, you may still need to tweak individual modelines for individual machines/games. It's definitely worth exporting your modelines and keeping a backup off the machine somehere, and saving your mame config too!

Thanks for your answer, definitely need to try.
The automatic generation is really a good feature
The bolded values do not appear in your mail, can you indicate the values ? Thanks
