bad graphics on psx emulator

[izhar]

Hello all
My project for Retropie with rpi2 and Berryboot go to the end. Now, i makes the settings.
Megadrive and snes works perfectly, but the psx, no.
I think, the shader isn’t use or maybe a problem with upscaling ?

Can you check the attached files and say me if you have an idea of my problem please ?

I’ve change shader (h2xq, h4xq, video_smooth, etc …)

the better will be less pixels and no lines ^^
Thanks

Hello, anyone has or had this problem ?
thanks

PSX graphics were very complex and designed to be displayed on a CRT. The sharpness of an LCD can make some of these graphics brutal to look at.

Not all shaders will work with the Raspberry Pi. Try the “crt-hyllian” shader in /shader/crt/crt-hyllian-glow/hyllian.glsl
(under options -> shader options)

make sure your scaling is correct. Set RA render resolution to 960×720 and keep your monitor at its native resolution. Hold “x” when launching from Emulationstation to bring up the menu to change this.

Set aspect ratio to “core provided” or “4:3”

set integer scale on (under video settings)

set crop overscan off (under video settings)

that should be all you need. If CRT-Hyllian is too heavy for your taste, try CRT-caligari instead.

also, you might try a different graphics plugin (under options -> core options)

hello
in shader, i haven’t CRT path.

/opt/retropie/emulators/RetroArch/shader/

it’s right ?

Hello
Iv’e try to other games, it’s not very good but no lines.
on tekken 3 and few games, lines always.

in my retroarch.cfg in “all” :

video_smooth = true
video_threaded = true
aspect_ratio_index = 6
video_scale_integer = true
rgui_show_start_screen = false

in retroarch in “psx” :

video_shader_enable = true
rewind_enable = false
video_smooth = true

Thanks for help

It should be there if you used the Retropie setup script. If not, you can download them here:

What is your video output resolution set to and what is retroarch render resolution set to? Hold down x or m when launching a game to bring up these options.

hello
960*720, i’ve set it in retroarch.cfg (path “all”)

[izhar]

hello
It’s the good resolutioon i think ?

You will get scaling artifacts with that setup if using a 1080p display.

See “list of recommended resolutions” and “how to get scanlines”

Sorry for contradicting myself, but I’ve learned recently that shaders aren’t optimal for the pi.

ok, thanks for your answers, i search it with your recommandations ;)
