@dcaputi said in moving mame back to lr-mame:

So ignore all that and just tell me, should I give FBNeo a try?

Unlike MAME's OSD, RetroArch's Quick menu > Controls isn't good at remapping anything to anything. I have a feeling this might be a problem with your setup. Make sure you read this if you want to try anyway.

And yeah, a lot of games supported by MAME 0.274 aren't gonna be supported by FBNeo, especially 3D games. As for the differences between both emulators, they are explained here and there.

@MCG_1983 Shaders work fine on old systems also. Please stop spreading misinformation in various topics or I'll consider you're just spamming.

@TPR said in Mesa Shader Cache - Can I delete this?:
You could rename the mesa_shader_cache first before you remove it.
Then you can always remove it later if you find that there are no problems.
Good idea ?

Yep. Very good idea. I'll rename it to see if there is any issues and if there are I'll just rename it back.

@mitu Forgot about this! Thanks for the reply! You're right the theme works fine with RetroPie 4.8 on the download page. I read that the theme would break....I don't dare update 4.8 though! (I may DD it beforehand and then try!).

Since you asked which theme it is (but it might be a little sketchy):

I certainly don't expect any support here for it.

Also when I installed 4.8 the slowdown when using shaders is much reduced and actually tolerable now. Happy days!

Next item on the agenda is to read up on overclocking the Pi3B+ because I wouldn't mind having run-ahead enabled.

Cheers mate!

This has been taken care of.

Download the below as zip:

extract to pc.

Move wanted shaders to:

[/opt/retropie/emulators/retroarch/shaders/whateverfolder/whatevershader.extension]

@sleve_mcdichael said in Shader Activation text in Retroarch.cfg?:

video_shader = "/path/to/shader.glslp"

Edit: if you want them enabled by default, use also:
video_shader_enabled = "true"

THANKS!

@sleve_mcdichael
Many thanks! that helped!

the whole problems started becasue i am too tidy and have my Roms organized in each console in a seperate "Roms" folder. Now this tihngs makes sense to me.

@Steve_C78 which shaders? which specific emulators? please fill out https://retropie.org.uk/forum/topic/3/read-this-first including verbose log

please read https://retropie.org.uk/docs/Shaders-and-Smoothing/

overlays + shaders compound the performance drain, so may not be feasible for all games. reducing resolution will help performance but reduce fidelity such that scanline shaders look awful, for example.

if you're seeing the thermometer icon, your pi is overheating and reducing internal clocks to reduce the temperature. fans/better case will at least allow it to throw as much power as it can at your config.

@mozvillat said in Graphics optimization (shaders):

edit : i've git clone https://github.com/libretro/slang-shaders, the path is slang or slang-shaders in the .config /retroarch/shaders ?
edit2 : if i do an online uptime, shaders are downloaded in $HOME/.config/retroarch/shaders/shaders_slang

I think either one is fine, the folder hierarchy beneath it should be preserved, since the presets reference individual shaders from it.

Can i assign a shaders for all emulators or have i to assign individually ?

You can assign per-core/folder/game/general, just save with the corresponding option from the Shaders menu - https://retropie.org.uk/docs/Shaders-and-Smoothing/#installation.

Hey there @ajlino ,

I am in the same boat as you with this issue. I have a 2 player cocktail table built running Retropie on a Rasp Pi 3.

I understand that not many roms support cocktail mode where the screen flips for P2, but I was hoping at least games like Pacman, DK, Galaga would work since the versions of roms I have appear to support this. But for the life of me I cannot get this screen flip to work at all on any game. I did manage to get Galaga to flip for P2 but it was all messed up and not playable.

Did you ever have any success on getting this screen flip in 2p mode to work? It's frustrating seeing videos online of people getting this to work with no issue at all, and I am following the same exact method.

Try to use 7Zip to open the backup .img and copy your files from it.

@sleve_mcdichael yes sorry

@jameelperkins31 Then please open a separate topic and describe your issue, adding the info asked in https://retropie.org.uk/forum/topic/3/read-this-first, instead of replying to random topics in the forum.

@mitu

Great! Thank you!

I also see the optimized settings I did for each game in there as well. Perfect!

@flagrant99 I have since learned some things.
glsl Shader format available to OpenGL.
glslp for GLSL stack these shaders to create a combined effect.

Only a glsl will get reloaded not the glslp with video_shader_watch_files ON.

@dankcushions Thanks for the quick response. Kind of sad that it's the effect of video transfer and not an improvement to the game itself. But I'll try that configuration change to see what it does for the game! I appreciate it.

@sharkytowers Your issue is not related to this topic.
For RetroArch Windows issues you'd better ask in the libretro forums - forums.libretro.com, which seem to be down at the moment - or on their Reddit forum over at reddit.com/r/retroarch.
