Add these gameboy shaders?

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.

@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.

@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?

Mydriaze

HEllo everyone, any update on this? I've tried the GB shaders too, but any is as good as the one show on this page. Any "good urinal color" shaders for the old GB?

Thanks for your reply.

Darksavior

@mydriaze I'm unfamiliar with the process, but I believe someone must port the shader to the pi. Even then, I'm not sure if the pi is fast enough.

Mydriaze

@darksavior Thx for your reply. I hope someone will answer this thread, just to know if someone is porting this shader. or if it's possible or not.

herb_fargus

@mydriaze you can swap out the palettes in the core options as detailed on the docs only works on the gb emulator though

Mydriaze

Thanks for your answer Herb. Hovewer, i'm not sure to understand rightly. When you speak about swapping through the palettes, you mean in retroarch?

Edit: to be honest, i'm a bitright now lost with shaders and overlays. I just look a video of Floob saying shaders are too CPU consuming, and overlays could be a good alternative.

Beside that, I'm still looking for my old love, the Blargg's NTSC Filter included in some Retroarch emulator, likev the Genesis one. Can I setup this filter in retropie or I must use olny the CRT-Pi shaders?

Sorry for the noob questions, but i'm a bit lost at the moment.

Mydriaze

I'm updating this post instead of creating a new one.
I'm lost guys. I will try to focus on the GB shaders/overlays issue.

Right now, i'm not happy with the offcial shaders/overlays in Retropie.

@herb_fargus : you've tried to help me, but I didn't understand exactly what you mean by "swapping out the palettes in tyhe core options". I think you speak about Retroarch core options. But what 's the point exactly?

I'm looking to something like this:

Is there someone who made it posible?

Hex

@Mydriaze It is easy. you need to go to the pallet and set it to internal with grayscale pallet to get something like this
