Default Resolution Error - All Emulators Affected
-
@k-shaps im not sure I fully understand ? In most cases the video modes don't need to be touched - you can just set a system wide resolution for example in
/boot/config.txt- for my set-up I use 720p for performance with shaders (screen is 1080p, but it upcales well). -
@BuZz That's definitely a viable option, for clarity here is an example (not from my machine) of where I am encountering issues. I guess the only thing is that I would want different resolutions for different emulators. I could settle for 720p across all, but for anything up until 1994 I would want to be in 1080p.
-
@k-shaps mupen64plus-gLideN64 scales up to whatever resolution you have - but I suppose it could look slightly different between dispmanx scaling vs tv scaling. You shouldn't need to mess with the framebuffer res - that won't have any effect here.
-
@BuZz Sorry should have clarified. I just pulled that n64 image from Google.
I mainly will be using my pi for MAME, NES, SNES, Neo Geo, PC Engine, GB, GBA, Megadrive, 32X, Sega CD, and Playstation. I have been setting the default resolutions for all of these emulators using the #4 option listed in the image above. This is the spot that is causing me trouble. If there is a way from within the terminal to set this per emulator I'm open to giving that a shot since I am hitting a roadblock from this menu. I'm assuming this is called the rom options menu? I get to it by pressing "a" on my controller after selecting a rom and before it launches.
-
@k-shaps This should work now - I think your videomodes.cfg just got corrupted or something - I will debug it with you if it's still a problem.
that is the runcommand launch menu btw.
There is a manual way of setting it, but it's better that we work out why it went wrong.
-
@BuZz So I tried renaming and got an error message. I'm guessing this means it's corrupted?
-
Your permissions have got messed up again. I can only think you are somehow running RetroPie / RetroPie-Setup under the root user or something as this keeps happening. Do you log in under root on the system?
-
@BuZz I'm not sure I know what you mean. Where can I check to see what I login under? I haven't changed any default settings after I installed the image if that helps.

So I don't know how but the issue is fixed:
The entire time I have been working through this resolution issue I have had my pi3 hooked into a computer monitor. The issues only started arising after I had plugged my pi3 back into this monitor after having it run into a 720p TV while on a trip. Last night I decided to actually play the pi3 instead of continuing to work on it so I plugged it into my entertainment center - routed the video out of the pi3 through and out my receiver into my 4K display...and viola...the issue was fixed. I had to adjust the screen settings as some of it was cut off but the resolutions are now changing and saving across all emulators.
Not sure how this could ever make sense but it is working now.
I guess the only question I have left is since I was having permissions issues in editing file names within configs/all do you think this issue goes deeper and something could still be wrong on the backend permissions wise?
-
Any thoughts on this Buzz? Still would like to work any kinks out in case this comes up again. I'm all for a bug free system. Quite OCD with the whole thing to be honest.
-
@k-shaps I don't know, but if it's working, don't worry :-)
-
Alright - this mess popped up again tonight. I had updated my retropie script, updated all packages, and scraped all my roms for art.
That's all I had done in terms of doing anything with the pi tonight. Now the resolution bug is here again. Now it is affecting the default resolution as well as the default resolution + rom.
Any thoughts why it would pop backup after what I had done?
Should I just go through with resetting the permissions again?

Alright...never mind. Fixed it again. You are definitely right Buzz. Seems that my permissions keep changing or something.
I was able to fix the resolution not switching by inputting the sudo chown command followed by the ls command in putty. Without restarting my pi I went into each system runcommand menu and adjust the resolution settings.
