Add these gameboy shaders?

edmaul69

so i figured out how to get it working. not as good as original because of the grid i had to add to it. in /opt/retropie/configs/all/retroarch/shaders/ create a file named "gb-pocket-shader.glslp". in that file insert this:

shaders = "5"
shader0 = "shaders/dot.glsl"
shader1 = shaders/gb-pass-1.glsl
shader2 = shaders/gb-pass-2.glsl
shader3 = shaders/gb-pass-3.glsl
shader4 = shaders/gb-pass-4.glsl

scale_type0 = "viewport"
scale0 = 1

scale_type1 = source
scale1 = 1

scale_type2 = source
scale2 = 1

scale_type3 = source
scale3 = 1

scale_type4 = source
scale4 = 1

filter_linear0 = false
filter_linear1 = false
filter_linear2 = false
filter_linear3 = false
filter_linear4 = false

textures = COLOR_PALETTE;BACKGROUND
COLOR_PALETTE = resources/sample-palettes/gbp-palette.png
COLOR_PALETTE_linear = false
BACKGROUND = resources/sample-bgs/paper-bg.png
BACKGROUND_linear = true

Chez swanky!

This is one of the most impressive shaders I've seen. Does it affect performance at all?

edmaul69

ignore this.

edmaul69

@mediamogul also it does not cause slowdown. it is nice. i am glad he brought this to my attention.

edmaul69

im not sure how the code was originally but this looks good on the pi but doesnt seem as nice as the pics you posted. can you post the contents of the shader you have?

Tasio

@edmaul69 This shader is included with the RetroArch but the one in the retropie is different.
The good looking is this https://github.com/RetroPie/common-shaders/blob/master/handheld/gameboy/gb-shader.glslp

works fine on windows, click for more quality

@Tasio and i cant get the grid with the settings that way. i had to change shader 0 to dot.glsl. no clue how to get the grid otherwise. but even this way is still better than the previous options on the pi. if i knew how to edit a .glslp file i would.

@edmaul69 Thanks. I tried your shader config but unfortunately, besides not looking that great, it makes the games so slow that they're unplayable.

edmaul69

@Darksavior i am aware. i was not happy with any shader for the gameboy. every overlay i have seen arent any good because they arent pixel accurate placed lines. i made an overlay specific to my screen resolution. for these to lookany good they have to be specific to the resolution size. not as good as that shader but i think its way better than anything on the pi at the moment for gameboy. if you are on a small device you will have to click on the pic to enlarge it to see how it really looks. i will settle on this for the time being. plus overlays have no slowdown. if you like it any i can make it in whatever resolution you are using. @mediamogul i would love your opinion or critique on this. Ive also played with rounding the corners a little but it doesnt display properly when i created this image since i just took a screenshot and then slapped the overlay on top of it since overlays dont appear in screenshots.

I think the overlay is a good compromise that still looks nice. Sure, it isn't as as authentic as the shaders in question, but since they're just too much for the Pi to handle, it's great to have this as an option.

@mediamogul can you do me a favor and take a 1080p screenshot of in game play of super off road not using horizontal stretching? I dont have a 1080p tv until i move back home 3000 miles away at the end of this month.

I wish those shaders worked. I absolutely love them. That mario pic just shows pure awesomeness. Its cool that it actually squares up all of the pixels because there are 4 different size pixels on the pi.

Here you go...

@mediamogul here you go. this is the green one to test. once you let me know if it is aligned right i will start a new thread. let me know if i need to move a pixel to the left or right. look along the edges of the black blocks. if you see a thin pixel line of the background color i need to fix that by shifting one pixel to the right or left. i may need to thicken the line too if it is too thin. i have full instructions for anyone testing it out. these lines of code go in your /opt/retropie/configs/gb/retroarch.cfg file:

input_overlay = /opt/retropie/configs/all/retroarch/overlay/"NameOfGreen1080Overlay".cfg
input_overlay_enable = true
input_overlay_opacity = 0.800000
input_overlay_scale = 1.000000

then you need to make a config to go with the overlay named the exact same as the overlay and put this info in it:

overlays = 1
overlay0_overlay = "NameOfGreen1080Overlay.png"
overlay0_full_screen = true
overlay0_descs = 0

then you need to name the overlays .png file the same as all the other info. then stick the overlay and the config file in /opt/retropie/configs/all/retroarch/overlay/

I'll set it up a little later this evening and let you know how it goes.

edmaul69

@mediamogul cool. Thank you.

mediamogul

@edmaul69

Alright, I think it lines up pretty well, but I'll let you be the judge:

@mediamogul any thoughts on how it is playing with it? I just now beat super mario land so it at least inspired me enough to play with it. If you think its good enough (of course nowhere as good as those shaders :( ) i will put together a zip file with a green, gray and black one for several different resolutions and post it on here.

@edmaul69

I played through a few levels of Kong 94 and it didn't seem to skip a beat. I'd say it's good to go. Nice job btw.

edmaul69

@mediamogul thanks. I do like that there isnt any trailing or weird effects you get from a lot of overlays because the pixels dont line up with the overlays. I just wish i had more control of the background color in this emulator with the existing shaders but i have tried and failed. I need to spend more time to get it working right.

How do i get the GB pocket shader?
