Problems with custom generated modelines
Zebidee:
Here are some pics to demonstrate 244p vs 240p (super resolution 2560x244@59 vs 2560x240@60) using the Wonder Boy title screen. There isn't a huge difference, but it gets you a few extra vertical lines.
Below is 2560x240p@60. The difference is more obvious in the corner pics. My "China TV" takes a very thin slice off the top of "PLAYER 1". It is right at the top of the screen, so you can see it reflected on the bezel.
Now (below) we have 2560x244p@59. The "PLAYER 1" text is now fully onscreen, the missing pixels are restored. No more reflection from the bezel.
With Groovymame, the gameplay is smooth despite the vertical frequency mismatch (59hz vs 60hz), even on my old Core2Duo E7400.
Regarding my China TV, it is actually pretty darn good and I've already fiddled the service menu to reduce overscan, but it still hides some lines. If you have a keen eye you may also notice that the yoke has a slight tilt, (the top left corner is slightly higher than it should be), and the image needs to come back to the right a little. It came like that from the factory, I'll find time to adjust it someday. Anyway, the yoke tilt means only "PLAYER 1" is sliced off in 240p, but not "PLAYER 2".
Also that wboy is 512x224, so 240p gives an extra 16 lines to play with. With proper 240p games more active lines will be hidden on this TV. Mostly it doesn't matter if it is just the top of "HIGH SCORE" missing, but depends on the game (for example, may matter more for vertical shmups)
So whether you use 244p or whatever for your TV is up to you, it is just another tool in the box.
Don't forget that from GroovyMAME 0.246 geometry controls are now available, try them first. However they are limited in that they can't adjust vertical size.

Yes, that was my idea, gaining some lines with 248p, but after doing what you explain, I get range errors with switchres/groovymame... IŽll find out.
GroovyMame 0.218 and even lower ones have those horizontal controls, I use them a lot.
I also got a universal/clone remote for the TV and I will try to get to service menu, but anyway, I appreciate all the patience. Thank you :)

In Vmmaker, go to fourth tab and make sure you are ticking the box to "export monitor settings to mame". If you don't do this then vmmaker and GM are working to different rules, not good. GM won't know what your monitor's cababilities are, and errors get generated.
If that doesn't work then you can produce a log file. See Calamity's sig for instructions - it is at the bottom of all his posts.

The geometry controls in latest GM (0.246+) are both in addition and better, great for CRT fans managing overscan. Worth the upgrade :)
