crt-pi shader users - reduce scaling artifacts with these configs in lr-mame2003, lr-fbalpha, lr-nestopia (and more to come)
-
@dankcushions ok, shall read. Red on another forum that they added a new aspect ratio to the index. so the custom 22 has moved to 23 instead.
So I just run in powershell:Get-ChildItem 'f:\cfg\*.cfg' -Recurse | ForEach { (Get-Content $_ | ForEach { $_ -replace 'aspect_ratio_index = "22"', 'aspect_ratio_index = "23"' }) | Set-Content $_ }
then added them do the dirs in retropie, works great..

@fomt -
Integer scaling
would interfere and takes priority over the custom viewports so you would want to leave it off. As @dankcushions pointed out it's probably off unless you turned it on.You already found the index change but also make sure you're in .cfg files are in the correct directory
/opt/retropie/configs/all/retroarch/config/MAME (0.78)
or/opt/retropie/configs/all/retroarch/config/MAME 2003-Plus
. That was a change that happened at some point too.If they are in the correct directory and you're using the correct index it will automatically show
Custom
due to every .cfg files basically is a custom viewport with a shader.If you it doesn't show
Custom
but the shader or an incorrect shader is working then it's probably been enabled on another level like the global, system or ROM. It shouldn't be set in core as these custom configs are core level.I guess also it might show
Custom
but be incorrect due to integer scaling. Basically in certain scenarios the video options don't display accurately depending on combinations of options set or also some backdrops will force resolution changes too. -
@Riverstorm Thank for the info
@dankcushions On another TV the screenmode is 1360x768. Tried to create cfg's with the script but I only got this in the config files,# Auto-generated crt-pi.glslp .cfg # Place in /opt/retropie/configs/all/retroarch/config/mame2003/ video_shader_enable = "false"
Do I have to change something in the script?
Or if you have time to create a zip with 1360x768 I would be thankfullEDIT:
It appears that my TV can handle 1366x768 resolution, so I will download those configs instead. -
@Riverstorm Could you please upload those modified scripts for the zfast shader, it'd be a real help.

This post is deleted! -
@omitrix02 - Here's a download link to the script files. It's been quite a while since I used them but they should still be valid. There's 8 files in the zip.
- crt-pi - mame2003
- crt-pi - mame2003-plus
- zfast - mame2003
- zfast - mame2003-plus
I modified the scripts so they could also be used for mame2003-plus. They are identical cores except for a few hundred games. Mostly mame2003-plus exclusives but there's also around a dozen or so that are 2003 only.
If a game is not in one of the resolution_db files (as they are getting older now) you can add an entry fairly easy by looking at what information is needed. It's a flat text file, one game entry per line and most of the fields are unused.
Another option is to find a clone or parent ROM .cfg file that has already been generated for the core and just copy/rename it. For example you can easily use the Donkey Kong .cfg file for Donkey Kong Remix, etc.
The other 4 files in the archive are just batch files to create both a 720 and 1080 set of cfgs at the same time. You can modify the batch file and add/remove the resolutions you would like to use for your setup. They aren't needed though if you prefer to just run python script from the command line.
Also I haven't updated FBA in a while (still running lr-fbalpha) so I don't know the exact path changes for new FBNeo core rename or I would modify it.

@Riverstorm Thanks for the scripts, as well as the detailed explanation, but I'm getting the same issue when I was editing the script myself: when using the zfast shader alongside curvature, the resulting configs will have completely empty lines. This only occurs with the zfast shader and curvature, as crt-pi works perfectly in all cases and zfast works when using 1920x1080.
-
@omitrix02 - Ok, I am getting the same issue using the curvature parameter.
From what I can tell something in the last commit (c89aee3) that was meant to correct a curvature issue broke it. Maybe @dankcushions can take a look.

@Riverstorm Hi, Can I use your script to mass-change the shader and resolution settings of my already installed Bezelproject game cfg files?
I couldn't look into the script because the download link has expired...
Thanks!
-
@ecto - I don't think it's possible or at least not easy. You can generate a new set and it shouldn't be to hard doing a compare of old and new folders to pull a new set of cfgs named the same. If you're using custom resolutions on a per game basis for bezels I don't see any easy way.
Here's a new download link to the files for you to take a look though. I made a few more modifications.
One set for the
crt-pi
shaders and one for thezfast
shaders. Also in the zip is theresolution_db
files. You only need to install Python and they should work.crt_pi_configs.bat
crt_pi_configs.py
zfast_configs.bat
zfast_configs.pyI modified the scripts so they could also be used for mame2003 or mame2003-plus. They are identical cores except for a few hundred games. Mainly mame2003-plus additions but there's also around a dozen or so that are mame2003 only.
I also added FBNeo but left FB Alpha for those still using the older core.
If a game is not in one of the resolution_db files (as they are getting older now) you can add an entry fairly easy by looking at what information is needed. It's a flat text file, one game entry per line and most of the fields are unused.
Another option is to find a clone or parent ROM .cfg file that has already been generated for the core and just copy/rename it. For example you can easily use the Donkey Kong (
dkong.cfg
) and modify it for Donkey Kong 3 (dkong3.cfg
), etc.The other 2 files in the archive are just batch files to create both a 1280x720, 1920x1080 and curvature set of cfgs, for all the cores at the same time and then zip them up. You can modify the batch file and add/remove specific cores and resolutions you're targeting for your setup.
The batch files aren't needed though. If you prefer to just run the python scripts from the command line similar to below which would not be zipped up but in a folder only.
python crt_pi_configs.py mame2003 1920 1080
For the other cores you can replace
mame2003
with the specific core you want. For the x (horizontal resolution) replace1920
for y (vertical resolution) replace1080
.For curvature just remove the resolution values and add
curvature 0
like so:python crt_pi_configs.py mame2003 curvature 0
.Core Names:
MAME 2003 =mame2003
MAME-2003 Plus =2003plus
FinalBurn Alpha =fbalpha
FinalBurn Neo =fbneo
Consoles =consoles

Hi
Riverstorm would you mind checking that download location, as it timesout :( TIA!
also could someone please re confirm the correct folder names in retropie/configs/all/retroarch/config for mame2003plus and for fbneo.
thank you so much, I'm running 1280 x 1024 and these scanline improvements have been so appreciated

@Riverstorm Thanks for uploading the scripts and explaining them once again!
Regarding my provious question, I think I may have come to a solution:
The Bezelproject just downloads cfg files for each game containing a path to the bezel (like here dondonpachi):input_overlay = "/opt/retropie/configs/all/retroarch/overlay/ArcadeBezels/ddonpach.cfg"
I will now just take your generated zfast_curvature cfg files and merge them into one file with something like
#!/bin/bash cd 'bezelproject_cfgs' for bezel_file in *.cfg; do zfast_file="zfast_curvature_cfgs/$bezel_file" cat "$bezel_file" "$zfast_file" > "merged_cfgs/$bezel_file" done
(Mind, I haven't tested the script, just googled away and found a solution to merge two textfiles!) Use at your own risk and only with backed up data!
Last thing worth noting is, that probably my Rpi3b+ isn't fast enough for handling bezels and a shader... That's at least what I learned reading through this thread. But that doesn't matter: It's alway fun to have new project going! Also, this paves the way for a future Rpi4! ;)
-
the scripts are all broken (again, but this time in a new way) with the latest version of retroarch :|
-
@dankcushions What happend?
-
@iainjh - Doing a quick download test it seems to be working fine.
The cfg files need to be located in:
/opt/retropie/configs/all/retroarch/config/MAME 2003-Plus
/opt/retropie/configs/all/retroarch/config/FinalBurn Neo
@ecto - Thanks for a solution to merge. The cfg file generated is fairly small with 4 comment lines and only 7 "functional" lines but still it could be a lot of work without a script. :)
I would also be curious as to what's broke with the latest RetroArch. I mainly use RetroPie and when downloading the latest RetroPie script 4.5.1 (896b34e1) and updating RetroArch it's still on 1.7.6. Everything in 1.7.6 works still so I am guessing it's something in 1.7.7 but I can't find a thread on what's broke.

@Riverstorm https://www.libretro.com/index.php/retroarch-1-7-8-released/
i've not tried it, but looks like the shader changes will break them.

Yes, the
video_shader
parameter has disappeared, hence any usage of it in a.cfg
file will be ignored. -
Some neat features in that version like the OCR, text to speech and CD support.
I use whatever RetroPie defaults to which I think is RA 1.7.6 which works well but it does look like when RetroPie goes to RA 1.7.8 some things will need tweaked in the script.
Example of new shader command line for RA 1.7.8:
retroarch --set-shader "D:\RetroArch\shaders\shaders_glsl\blurs\kawase_blur_5pass.glslp" -L <core> <content>
Example with relative path:
retroarch --set-shader "shaders_glsl\blurs\kawase_blur_5pass.glslp" -L <core> <content>

thanks, I tried again and after a few goes it downloaded. thanks also re the paths!
I'll avoid updating retroarch.

Hi all
Stupidly, I've managed to lose the file "crt-pi-configs-master-prod.zip" and the download link requires a subscription. Could someone please share the file?
I have acquired a new monitor panel and need to output new .cfg's for its 1600x1200 resolution
Also, back over my normal pi (pi4, most recent retropie, 1280x1024 monitor and the .cfg's created above) it appears the optimum vertical mask and sizing works perfectly even though the last posts indicated some problems with recent retroarch builds. Are those issues now fixed?
But I have a new issue. The display on some games is now upside down! Donpachi for example. Has anyone else seen this or could suggest how to fix? ive added:
video_allow_rotate = "true"
video_rotation = "2"with no change.
thank you very much for any pointers! scanlines FTW!:)
