crt-pi shader users - reduce scaling artifacts with these configs in lr-mame2003, lr-fbalpha, lr-nestopia (and more to come)

UDb23

@dankcushions
Had to make some changes to my previous code. It now runs correctly; here's the generated comma separated resolution file.
Based on current DAT for 2.97.44.

Notes:

some roms cannot be found on Progettoemma's site; as far as I could checks these are hacks or particular clones.
Concerning clones I started editing the DB manually adding the original game screen info; it will take some time.
aspect ratio values and frequency are currently dummy figures (let me know if you need the real one's)

Out of 5552 roms from the DAT, over 90% are already included in the resolution DB txt file.

@UDb23 great! thanks - i'll try and take a few hours to test it out sometime soon <3

@dankcushions Maybe its a stupid qiestion. but can I use this cfg's for games running with mame2010 and fbalpha2012?

hi! i would have thought the fbalpha configs should work with fbalpha2012 since its romset should be a subset (or close to) of the later fbalpha, but mame2010 will have many games that are not in mame2003, which i won't have configs for. however it probably has most of the common ones, so it can't hurt :)

you just have to put the mame2003 configs in the mame2010 folder, and the fbalpha configs in the fba2012 folder.

@dankcushions Ok, thank you reply! Another question, for example in /opt/retropie/configs/all/retroarch/config/MAME 2003 I already have config files for all the games, for example 3countb.cfg contains:

input_overlay="/opt/retropie/configs/all/retroarch/overlay/ArcadeBezels/3countb.cfg"

and that file in ArcadeBezels dir contains:
overlays = 1
overlay0_overlay = 3countb.png
overlay0_full_screen = true
overlay0_descs = 0

If I overwrite that files in Mame 2003 folder, then I guess the overlay input will not work. Do I have to edit every file and copy and paste your files into these files that I already have there? Or is it another easier and faster option to do that? :)

@fomt the scripts slightly change the aspect ratio of the games so wouldn't be compatible with any overlays you have as they presume the standard aspect ratio. you'd get stuff overlapping, etc.

fomt

@dankcushions ok, then I guess I can overwrite the files with yours and skip the overlay images.

Hi all! I'm wondering if I can apply this method to the picade cabinet I'm working on - The resolution is 1024x768, and I'm going to be using MajorDangerNine's romsets from here:

https://retropie.org.uk/forum/topic/20348/all-in-one-overclocked-rpi3b-arcade-rom-set-setup

This uses FBA v0.2.97.44, MAME 2003 Plus, and MAME 2010.

@Aksen Shaders work best at 1080p. With that low res, I don't think it's worth using shaders.

Aksen

@Darksavior Maybe so, but I still like 'em

@dankcushions I tried to get the console configs for the x768 resolution and the link is broken; my TV uses an odd 720p resolution (the previously mentioned) and I want those bars gone :)

dankcushions

all the cfgs are available here: https://drive.google.com/open?id=0B_51EcTfJiTqME44R3E3ZU5kdFU

however they won't work as per https://github.com/libretro/RetroArch/issues/7536

i need to fix the script and rebuild them all but my (tiny) protest about how retroarch handles unneeded and (IMO) foolish config changes like these is to not fix the mess they create (i probably will once they actually respond to my issue, though)

A temporary workaround of what changed and needs to be modified in the script can be found in this thread in the last post.

Here's a link to the script. You can use something like Notepad++ to make the modifications. It's only a few lines and it works well.

I could upload them. I think I have a few scripts modified for the mame2003/FBA and mame2003-plus/FBA changes using either the crt-pi or zfast shader.

@dankcushions @Riverstorm thanks to both of you

Hello again. Last time I used these configs for my 1080p I didnt really know how to use them, i had ”core privided” to every game so I guess these configs never worked. 😵
Now i’m want to use them on a new install, and I have put them in the desire folders, and the shaders are working. If I change from ”core privided” to ”custum” in retroarch then I think the aspect ratio works to. Am I doing it correct? Should I have it on custom only or should I also have ”integer scale” on?
If yes, how do I set ”custom” as default? As now I have to change in every game. Should I edit retroarch.cfg?

fomt

Think I must change:
aspect_ratio_index = "22"
to
aspect_ratio_index = "23"

EDIT:
Yep, 23 works, custom must have been changed from 22 to 23

should I add "video_scale_integer =true" in /opt/retropie/configs/arcade/retroarch.cfg ?

no :)

fomt

@dankcushions No? What should I do then?
So then I guess integer scale should be OFF?
