crt_emudriver stopping mid-scanline?

<< < (3/3)

rogerxyz:
Thanks as always Zeb, you really helped me untangle this.

I had thought I reverted to vanilla ntsc but perhaps what happened is that VMM modified another GM install's mame.ini. That should teach me, if I keep around old versions I should at least make /mame, a fixed path, the current one or something.

So, I did this to myself, and here's how:

* I tweaked the VMM timings by pushing this particular set to the very edge until it lost sync
* I used that to generate new modes
* I didn't quite realize that, stable sync doesn't mean every scanline can be drawn, so I inadvertently created my own modelines with these problems
Indeed, when regenerating modelines based on vanilla NTSC, and when making sure this actually modifies the RIGHT mame.ini, I don't have the >240 line modes and, for example, Ninja Spirit displays 480i or something and the whole image is visible. Readjusted my geometry for the new timings and I think I'm back on track.

Lesson learned!

UPDATE: Okay there was one new problem, but easy enough to fix. The first 2 modelines generated crashed my graphics card, so I set the minimum dotclock to 4.7MHz and now I think I've got a usable set.

Please not that it's rather TVs problem not a modelines since such behavior I can observer on original SNES on my TV for example on Konami white logos last line ends in the midle.

In my case Sony TV was problem.
