@strells said in Auto aspect ratio for vertical games?:

I left integer scale turned off so that the image, whether vertical or landscape, reaches the edge of my Arcade1Up 17

Just be aware that not enabling integer scaling is not recommended because it will cause gfx issues due to bad nearest rounding, those gfx issues being more or less noticeable depending on the context.

Great. I did not know that. Thank you for the heads up!

@romstar said in What's the correct aspect ratio I should be using as a config for a HAPP / VISION PRO 19" LCD arcade monitor for MAME Horizontal / Vertical games:

I changed the bottom line to mame2003_tate_mode = "enabled" which ultimately resolved my issue. now The vertical game is finally displaying the way it should on my HAPP Vision pro monitor mounted vertical !! At some point I'd like to build a vertical only list of games and have the menu / retropi running exclusively in vertical mode.

I knew it would change your life. I would not recommend trying to make the whole of retropie itself work in vertical mode yet, though. I stayed with my rotating monitor because rotating emulationstation causes performance issues. I believe it also became more difficult to rotate emulationstation on the Pi4 because the option was deprecated. I stayed with my Pi3b for my vertical MAME games for that reason and hope that a good solution for a fully vertical system presents itself later.

@mitu

Turns out I'm a complete dope.

I figured out what I've been doing.

I thought I had been setting the rendering resolution of the game.

What I had actually been setting was the Pi video output resolution over HDMI to the monitor.

So in the end I now have my games running properly. They are being rendered at 640x480 in the emulator as they should, and I'm outputting dreamcast games at 720p to get a bit more performance. Every other system I left at the default output of 1080p.

@alphabetapie Have you made (or found) some good overlays? Which ones? :)

Open the runcommand launch menu when launching an arcade game and check if there isn't a video mode specified for all the games running with the arcade emulator.

@dankcushions said in (SNES9x) Core options aspect ratio vs Video settings scale aspect ratio:

by default it looks like options > preferred aspect ratio = 4:3 by default - https://github.com/libretro/snes9x/blob/master/libretro/libretro_core_options.h#L81, so you must have changed it at some point, yeah.

Yup, I just set up a clean RetroPie 4.7.1 card, and the defaults give full 4:3 for Snes.

Not for Megadrive though: for the lr_genesis_plus_gx default configuration the game image is not quite 4:3 - skinny black bars at left and right. The default config probably wants aspect_ratio_index=0 (for 4:3). Or a little overscan?

i wouldn't want to make assumptions. it could be true to the real hardware. you'd have to drill into the core options and/or the code, but since we use 'core provided' as our default, and generally use default core options, the default aspect ratio is at the discretion of the core developer, so it's typically intentional.

@dankcushions well thanks you for assisting me with this one. I eventually got it working by using the USA Rom and, as you suggested, stretching the image to 5:4. it fills the whole screen and looks good. I'll be happy with that solution for now. Happy Holidays.

@scoularis please provide a verbose log of the issue, and the override .cfgs involved.

@superfella still, that's the information I would need to diagnose. take it or leave it...

I have a Pi 3b and SI95 runs absolutely horribly in lr-mame2003 and lr-mame2003plus, which is why I was running it in AdvMAME in the first place.

Not sure what you mean - RetroPie doesn't configure a specific video aspect, it uses what is available on the system.

Big update, reinstalled daphne and problem solved !

Playing with the sourcecode, I usurped the 8:7 PAR to be just 8:7 like 4:3. The switch that controls this is a boolean and I haven't the time to change it right now (and then I would need to make a github account to request a pull for the changes).

@mitu said in N64 emulator doesn't save any settings:

you need to save a game or core override after you've changed the parameters

Can you please tell me where I can find the Overrides-menu? Or which solution would be the best?
When I switch the "Use Global Core Options File" to OFF, then I still the the same problem.

@pojr said in RetroPie stuck in 4:3 (the interface, NOT the games):

@dankcushions
I don't think it would be 81, but you are correct that it's wrong. Shouldn't be 16 because my TV only displays up to 720p, not 1080p. Although it is a 16:9 TV (not 64:27 like it shows under #81). Also, my TV frequency isn't 30Hz, unless I'm missing something.

you've fixed it now so i guess this is irrelevant but yes, you'd need to use hdmi_group=2 for 81 - it doesn't seem to be supported under 1. but yes, @mitu 's suggestion would get show you the complete list of supported modes. given that it's less than 4k, i would always want to be running in the native panel resolution so you don't get scaling artefacts.

i assume now you've taken out hdmi_safe you can safely take out any hard coded modes and it should hopefully choose 1366x768 by default.
