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

[GreenHawk84]

@dankcushions lol I know

[davej]

@twd
I can't answer your "how many vertical games" question but it's worth pointing out that if you have vertical screen you need to use the opposite versions of the shaders. So the normal shader with vertical games and the vertical shader with horizontal games.

@dankcusions
Could you produce a set of files using the opposite shaders for those with vertical screens?

[GreenHawk84]

@dankcushions but can you help me on this side note, how do I get these options back to normal in RGUI?

[twd]

@davej ahh ok thanks bro just going to make it ...if there is 50 games I will be happy

[dankcushions]

i'm going mad :) here's what i said earlier:

if you open the zip you can see the total number of files/games. ~1500

that's ~1500 vertical games in mame2003. if you open up that zip file you'll see ~1500 files. one file for each vertical game.

@GreenHawk84 you're on your own here. i've no idea what you've done to your system. i just wanted to make some cfg override files for vertical games :/

[twd]

@dankcushions thanks buddy ... 1500 is a lot i don't have a pc to hand on a iPad so I cannot download the zip to check so thanks for the info...

[GreenHawk84]

@dankcushions thats okay, I at least got "per game core" to save as "off" however "save on exit" will not hold if I try to set it off.

Back to your instructions on vertical shader; I went in with WinSCP and to the folders you suggested. However, I did not see a Mame2003 folder as said at the end of your folder path: /opt/retropie/configs/mame-libretro/MAME 2003/

How do I install this shader to RetroPie? How do I update the existing crt-pi shader?

Thank you!

Thank you!

it is already included in the latest retropie image. if you don't have that, you should update retroarch via binary: https://github.com/retropie/retropie-setup/wiki/Updating-RetroPie#updatinginstalling-individual-packages

[Pyjamarama]

@dankcushions Can you confirm the paths plz? I have no MAME 2003 folder inside /opt/retropie/configs/mame-libretro/

I put the configs in /opt/retropie/configs/mame-libretro/ but no change...still user crt-pi

thank you

[dankcushions]

@Pyjamarama you create the directory.

[Pyjamarama]

Hmmm...I did but did not make the trick.

What did it is...I put them in the folder where I have the roms and renamed them from filename.cfg files to filename.zip.cfg (just a batch rename using TotalCommander)

It worked smooth like Kylie's @@@ :)

Thank you for your help (and your configs!!)

[GreenHawk84]

I could not get this to work, even by creating the MAME 2003 folder in either configs directory. So I just renamed the files I needed with .zip as Floob suggested and all is well. Hopefully this can be implemented automatically at some point.

[dankcushions]

@GreenHawk84 @Pyjamarama
in my first post:

please check if it works and confirm, as i'm not sure what version the overrides functionality arrived in retroarch. it should be in retropie 4.x but i'm not sure.

without knowing what version of retropie you're using i won't know anything about your problem. if it's the latest, i guess it's only in very new retroarch builds. you could update retroarch from source to test that theory.

also, please post the full path of an example game and appropriate override config so i can be sure you have it set up right.

using zip.cfg files in the rom directory is the retropie way of doing it. my way uses retroarch functionality, which IMO we should move toward. read this for more details: https://retropie.org.uk/forum/topic/4055/idea-use-retroarch-s-built-in-per-rom-config-functionality-rather-than-runcommand-and-appendconfig/5

[Mamemeister]

Guys, I did this and found it didn't look great so tried to disable it but despite turning off all the shaders options in Retropie options AND deleting the Mame2003 folder with the config files the scan lines are still enabled, any ideas how to turn them off would be wicked thanks.

Update / discovered if I went into the individual emulator options ie Arcade and FBA and turned off the video shader that works.

@dankcushions

Thank you for all your hard work.

I edited the mame2003-crt-pi-vertical-overrides and created one with the names changed to .zip.cfg so these can go right in to the roms folder.

Here mame2003-crt-pi-vertical-overrides-cfg (Put in roms\mame-libretro)

Here is also one with mame2003-crt-pi-curvature-vertical-overrides

And last one mame2003-crt-pi-curvature-vertical-overrides-cfg (Put in roms\mame-libretro)

@dankcushions said in crt-pi shader users - automatic usage of crt-pi-vertical in vertical games in lr-mame2003:

for the curious, i created a little script that went through the lr-mame2003 source-code and pulled out the list of roms that are rotated, and from that it created the relevant .cfg files. we could potentially do the same for other arcade emulators but i'll leave that for someone else.

I'm interested in how you did this. I have several plans for creating cfg's for games that are not vertical and add a standard arcade overlay beazel for them.

Same for fba neogeo only roms and so on.

with mame(2003) it was easy as the source code has easy to find strings for all the vertical games. eg:

https://github.com/libretro/mame2003-libretro/blob/7b55725e744ac9702db092f996e2fca2276146b2/src/drivers/pacman.c#L4356

GAME( 1981, maketrax, crush,    pacman,   maketrax, maketrax, ROT270, "[Kural] (Williams license)", "Make Trax (set 1)" )
GAME( 1981, maketrxb, crush,    pacman,   maketrax, maketrax, ROT270, "[Kural] (Williams license)", "Make Trax (set 2)" )
GAME( 1981, korosuke, crush,    pacman,   korosuke, korosuke, ROT90,  "Kural Electric", "Korosuke Roller" )
GAME( 1981, mbrush,   crush,    pacman,   mbrush,   0,        ROT90,  "bootleg", "Magic Brush" )
GAME( 1981, paintrlr, crush,    pacman,   paintrlr, 0,        ROT90,  "bootleg", "Paint Roller" )
GAME( 1982, ponpoko,  0,        pacman,   ponpoko,  ponpoko,  ROT0,   "Sigma Enterprises Inc.", "Ponpoko" )
GAME( 1982, ponpokov, ponpoko,  pacman,   ponpoko,  ponpoko,  ROT0,   "Sigma Enterprises Inc. (Venture Line license)", "Ponpoko (Venture Line)" )

anything with ROT90 or ROT270, i know is a rotated CRT screen so is a vertical game. you can get the zip name from the same string. i used some REGEX in a little python script to get the info (i think... i can't find it now). i then wrote this python script to go through that list and build the .cfgs:

fileName = "rotatedgames.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 + '.cfg'
    newCfgFile = open(cfgFileName, 'w')
    newCfgFile.write("# Auto-generated crt-pi-vertical.glslp .cfg\n")
    newCfgFile.write("# Place in /opt/retropie/configs/mame-libretro/MAME 2003/\n")
    newCfgFile.write("video_shader_enable = \"true\"\n")
    newCfgFile.write("video_shader = \"/opt/retropie/emulators/retroarch/shader/crt-pi-vertical.glslp\"\n")

myFile.close()

i had a quick look at FBA and the code didn't lend itself to the same approach i think.

@dankcushions

Thank you for posting you script but for me this is useless because i don't know how to use python.. Yet.

But maybe you can help me nonetheless .

I have here a complete list of all the neogeo roms present in FBA 0.2.97.39 (New version right around the corner)

Can you help me create or guide me to how i can make cfg files with these templates?

Content of 2020bb.cfg In /home/pi/RetroPie/roms/mame-libretro/ "for example"

video_shader = "/opt/retropie/emulators/retroarch/shader/crt-pi-curvature.glslp"
video_shader_enable = "true"

input_overlay = /home/pi/RetroPie/roms/mame-libretro/overlays/2020bb.cfg
input_overlay_enable = true
input_overlay_opacity = 0.800000
input_overlay_scale = 1.000000

aspect_ratio_index = "0"

video_scale_integer = true

Content of 2020bb.cfg In /home/pi/RetroPie/roms/mame-libretro/overlays/

overlays = 1

overlay0_overlay = Final_Arcade_NeoGeo_Horizontal.png

overlay0_full_screen = true

overlay0_descs = 0

I was thinking about using this as an overlay Final_Arcade_NeoGeo_Horizontal
