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

Rion

Thank you again @Riverstorm for explaning this to me.

I got it working

Here is the code

fileName = "fba_neogeo_029739.txt"
myFile = open(fileName, "r" )
print('opened file', fileName)

for gamename in myFile:
	# strip line breaks
    gamename = gamename.rstrip()
    print('creating .cfg for', gamename)

    # create cfg file
    cfgFileName = gamename + '.zip.cfg'
    newCfgFile = open(cfgFileName, 'w')
    newCfgFile.write("# Auto-generated crt-pi-curvature .cfg for NeoGeo\n")
    newCfgFile.write("# /home/pi/RetroPie/roms/mame-libretro//\n")
    newCfgFile.write("video_shader_enable = \"true\"\n")
    newCfgFile.write("video_shader = \"/opt/retropie/emulators/retroarch/shader/crt-pi-curvature.glslp\"\n")
    newCfgFile.write("input_overlay = /home/pi/RetroPie/roms/neogeo/overlay/Final_Arcade_NeoGeo_Horizontal.cfg\n")
    newCfgFile.write("input_overlay_enable = true\n")
    newCfgFile.write("input_overlay_opacity = 0.800000\n")
    newCfgFile.write("input_overlay_scale = 1.000000\n")
    newCfgFile.write("aspect_ratio_index = \"0\"\n")
    newCfgFile.write("video_scale_integer = true\n")

myFile.close()

But i could not get
newCfgFile.write("input_overlay = "/home/pi/RetroPie/roms/mame-libretro/overlays/$cfgFileName"\n")
to work.

Luckily because this was only NeoGeo games i could point them all to one cfg file in the overlay folder.

But i would like to solve it when i start to look at adding a generic arcade-bezels to vertical games in lr-mame2003.

Anyway here are the results for everyone to download.

Just put them into you neogeo roms folder in "/home/pi/RetroPie/roms/neogeo"

neogeo-crt-pi-curvature-Final_Arcade_NeoGeo_Horizontal-bezel-.zip.cfg

Here is how its going to look when finished.
SNK NeoGeo

Thanks to:
John.Merrit over at libretro forums for creating this in the first place.
@dankcushions for the python script!
@Floob for his work with rp-video-manager and making these work for the pi.
@Riverstorm For explaining this to me in an easy way ;)

That's great! I know that variable is probably the issue. It's just my lack of knowledge of Python. You might try the line below. I think that will work. Basically you enclose in quotes before and after the cfgFileName variable concatenating it all as one string with the plus sign. It's a little more confusing with extra \ and " throughout the line but basically the same as before. Basically "string" + variable + "string" but we want double quotes to enclose the string after the = sign so there's two extra \" in the line. For example after +cfgFileName+ in the line if you remove the beginning and end quotes it's basically \" (double quote) and \n (new line).

You probably know this :) but both the config file and overlay file are the same name: <game name>.cfg you would need to take that into account so they don't overwrite each other. You could run write it out to another directory or run it in a separate folder.

newCfgFile.write("input_overlay  = \"/home/pi/RetroPie/roms/mame-libretro/overlays/"+cfgFileName+"\"\n")

Well that did the trick!

Thank you. Now lets start looking at the Generic Bezel for vertical games... :)

BTW, I found that I needed to put the override .cfg files here to get them to work with Retropie 4:

/opt/retropie/configs/all/retroarch/config/MAME 2003

I'm going to try this tonight! Thank you!

I've done this manually twice recently! ...thankfully I only play around 100 MAME games total so there weren't too many vertical ones.

@dankcushions so i created a folder called MAME 2003 in /opt/retropie/configs/mame-libretro added all the files and it didnt work. then today i updated rpie setup script then updated mame 2003 from binary and still doesnt work. still only sees the crt-pi.glsl i have tried many roms. i am on a pi 3 with retropie 4.01 but i updated retroarch yesterday and mame 2003 today

Since i have no special mame configs and since i couldnt get this to work so i just used bulk rename utility to add the .zip into the names.

Rion

@edmaul69 strange.. I'm using RetroPie 4.1.
Have you tried the ones i posted?

edmaul69

@Rion i just put yours directly in my roms folder since you already had the .zip in the name. I dont know what the folder name was supposed to be where to put yours in the fba config folder.

Rion

@edmaul69 The ones i posted are for mame not fba.

But if your looking for fba look here

edmaul69

@Rion i was talking about those fba ones. im sorry i didnt realise you had a mame set as well. do yours still go in a folder named MAME 2003? or do i keep them in the folder you get from the zip?

Rion

@edmaul69 The ones i posted goes in to the rom folder not mame2003.

@dankcushions @Sharkus @Dochartaigh

Updated for RetroPie 4.1

mame2003-crt-pi-vertical-overrides-.zip.cfg

mame2003-crt-pi-curvature-vertical-overrides-.zip.cfg

Place these in you mame-libretro or arcade folder.

how are these 'updated' for 4.1? the mame gamelist hasn't changed.

also, whilst i appreciate your effort i think your alternative versions are confusing this thread and unnecessary. the ones i uploaded in my original post should work for anyone using retropie 4.1. your .zip.cfg overrides in the rom folder are a retropie hack made before retroarch supported per-game cfg overrides. there's no need for that approach any more, and maybe it won't always be supported.

i think we should use the properly supported retroarch way as it has advantages. for example, if you use a .zip.cfg rom override with config_save_on_exit = true in your main retroarch.cfg, your per-game shader override will migrate to your main retroarch.cfg. this doesn't happen with the supported approach.

dankcushions

i see, the shader location has changed in 4.1. i will update my .cfgs.

still, unless someone can give me a good reason for keeping the .zip.cfg versions, i will be cleaning up this thread

Rion

@dankcushions

Sorry about that i should have been more clear about the .zip.cfg files i posted. Do you want me to remove these and add the cfg files only or post both for people to choose?

I have also posted this

Mame2003 (0.78u6) Generic Arcade Bezel for every game with crt-pi-curvate (vertical & horizontal)

And this

crt-pi shader users - automatic usage of crt-pi-vertical in vertical games in lr-fbalpha 029739 (formerly lr-fba-next)

Same here with only .zip.cfg files. Do you want me to Change these to and only post the cfg files or both?

dankcushions

@Rion thanks! yeah for me the cfg files only should be the ones we use. i don't see the reason for the .zip.cfg ones going forward. i will update my initial post once i've re-run my script with the new shader directory.

Rion

@dankcushions Ok i will update my posts with the cfg files during the evening.
