Stretched screens when using RGB/Composite/Svideo filter in an emulator

[Mydriaze]

Hello,

Everything is in the title.

When playing a Sega Genesis game, I go into “core options”, then select Blargg’s filter RGB/Composite/Svideo, but the screen get stretcg automatically. If I disabled it, no more stretching. I really love this filter, but don’t know how to fix this strecth effect.

By the way, where can I add the default path for roms in “settings>directory”? Not sure which path I need to change to be honest…

Thanks a lot for your help, and sorry for my English.

Hmm. No change here. Can you post a screenshot?

[Mydriaze]

Better. A movie!

My roms extensions are not .zip or .rar or .7zip, but original .gen, don’t know if it helps.

[hunterk]

Yeah, that’s a pretty convincing video. I just tried to reproduce it here but got no stretching, so there must be something up with your settings.

First off, what’s your aspect ratio setting? Mine’s ‘core-provided’.

[Mydriaze]

In setting > Video > Aspect Ration Index is “config”.

I’m not 100% sure i’m looking at the right place. Didn’t find the “core-provided” option.

That’s in “aspect ratio index”, just 2 steps under your selection in your screenshot. Try it on “Core provided”.

edit: didn’t read that right, you saw that setting… can’t you see core provided when you move left and right?

[Mydriaze]

Yes, I can see it, and it fix the aspect issue! Thanks a lot for your help. By default, it’s on “config”, but when “core provided” is on, no more problem. Thanks a lot.

Can I ask you another question? Don’t know if I have to create a new topic or not, but feel free to not answer if you prefer that I create a new thread.

I love the GB shader, the one who simulate the yellow-pixel screen as the original GB. I know how to launch it and it works perfectly. But when I’m launching another core, the shader stay on the screen. I’m pretty sure I have something to do with “configuration per core” ON, but it didn’t work. Do I have to do “save new configuration” each time? Or “launch configuration” each time?

I would like to be able to configure each core separately. If i’m launching a GB game, the shader will automatically display. If i’m lauching a SNES game, the shader won’t display. Don’t know if i’m clear in my explanation… Anyway, thanks for your help.

I’m using per-core config for that and that’s working. Perhaps some of your settings clash with each other.

Mine, in Settings>Configuration are: Save config on exit — ON Config Per-Core ------ ON Load Override Files - OFF LOAD Remap --------- OFF

Or you can go a different way with Override files (disable Per-Core Config then) like explained here.
