All files can be found here:
To make the screen looking green you need to store the file default.pal into the folder:
Then edit the file
and change the value of gambatte_gb_colorization to “custom”
The PSD can be found in the dropbox address, I did put the grid, pallets and the gameboy itself in different layers to be easier to edit.
aspect_ratio_index = "22" custom_viewport_width = "358" custom_viewport_height = "323" custom_viewport_x = "248" custom_viewport_y = "79"
PS: I’m still not satisfied with grid overlay yet, I’m open to suggestions.
I made a better viewport mapping and also I changed slighly the PSD.
Also added to dropbox a file called “gb.cfg” with settings I used to put into retroarch.cfg file or to make an #includerobertybobParticipant12/19/2015 at 23:30Post count: 219
Where do I store the rest of the files in the .zip? Do I create a new folder in /opt/retropie/emulators/retroarch/shader and if so what do I call it?FloobMember12/19/2015 at 23:54Post count: 1629

default.pal = place in /home/pi/RetroPie/BIOS/palettes/
gb1080p.png = optional overlay
gb1080p.psd = only needed if you want to create a new custom overlay yourself
preview.jpg = not needed
If you want to use the gb1080p.png overlay, put this in your /opt/retropie/configs/gb/retroarch.cfg
aspect_ratio_index = "22" video_scale_integer = true custom_viewport_width = "358" custom_viewport_height = "322" input_overlay = /path/to/your/gb1080p.png input_overlay_enable = trueeightkillerParticipant12/30/2015 at 19:43Post count: 8
Really nice work guys, it works like a charm. I just have a question, i still don’t get quite right how u manage to calculate the proper “custom_viewport height and with” and the “x and y position”.
I read all the post on the forum about this for other overlays for other emulators like snes etc., which works well too. But i don’t get how u figure the proper numbers including your “gameboy painting around the gaming area” or not including it for example.
Natively, if i got it right, the GameBoy has a 160×144 resolution, so what have been ur process to end with a
custom_viewport_width = "358" custom_viewport_height = "323" custom_viewport_x = "248" custom_viewport_y = "79"
If u could explain it to me again because i read things about this already but it’s not cristal clear and i would like to try to create some customized overlays myself ! I would be grateful for your help !
See u soon on the forum :pLodanZarkParticipant12/31/2015 at 20:56Post count: 69
To create the PSD, I made a rectangle shape with 160×144, and then I rescale it without losing the proportion by pressing shift until get a cool size (804×724)and then I did position the that rectangle in the center of image to help me define the gameboy display zone.
My difficulty was mapping the position and size over the custom_viewport, mostly was over mess around with numbers until fits the screen, I don’t know which resolution output its processed by the emulator though :\
I should tweak 358×323 to 358×322 to have the same scale as 160×144 and 804×724, I will update the viewport mapping soon
358×322 has a better scale yet it causes a blank horizontal pixel line in the bottom, I think the issue its related with custom_viewport_y = “79”, if i set value as “80” creates 2 or 3 blank horizontal pixels lines on the top, plus I cannot set the custom_viewport_y = “79.5”…
I don’t know hat i should do, if let keep the 358×323 resolution on viewport or add a extra pixel line on the bottom into PSD file.suprmonky73Participant01/05/2016 at 17:53Post count: 2
thanks for posting this, its awesome!
So i was having an issue getting Retroarch setup to use the PNG overlay.
One thing that noobs like myself not realize is that the Input_overlay command needs to point to a .cfg file, and that .cfg file points to the .PNG file.
So the .cfg file is here:
and says this:
overlays = 1
overlay0_overlay = gb1080p.png
overlay0_full_screen = true
overlay0_descs = 0
Then in your
/opt/retropie/configs/gb/retroarch.cfg file you add this stuff as mentioned above
aspect_ratio_index = “22”
video_scale_integer = true
custom_viewport_width = “358”
custom_viewport_height = “322”
custom_viewport_x = “248”
custom_viewport_y = “79”
input_overlay = /opt/retropie/emulators/retroarch/overlays/borders/gb1080p.cfg
input_overlay_enable = true
I was assuming that the input_overlay was supposed to point to the PNG file’s location when in fact it needed to point to that overlay/borders/ location.
Is this the correct way to set it up? i got it working like this at the very least!LodanZarkParticipant01/05/2016 at 20:10Post count: 69
the file “gb1080p.cfg” should be in same folder as the png file, otherwise you need define the full path in the tag overlay0_overlay = /path/to/your/filename.pngKeiganParticipant01/24/2016 at 20:29Post count: 52
Shouldn’t you have made it 800 x 720?
Now maybe the 4 extra pixels will make no difference, but I suggest that since it’s exactly 5x the original size. If you try to blow up an image 5.2% and keep nearest neighbor intact it’ll distort the pixels since it’ll blowing up 1 pixel into 5 in some cases and 6 in others causing the output to not have square pixels.LodanZarkParticipant03/16/2016 at 18:18Post count: 69
I just had update the overlay, I did some upscale and made it work with proper resolution scaling,
here the new settings:
aspect_ratio_index = "22" custom_viewport_width = "380" custom_viewport_height = "342" custom_viewport_x = "237" custom_viewport_y = "70"LodanZarkParticipant03/18/2016 at 05:39Post count: 69
I made a little update, I increased the space between display zone and border, plus I added a better grid, yet if you prefer the older one you can find it on psd file.LodanZarkParticipant03/20/2016 at 16:35Post count: 69
Since the resolution was uncapped in latest commits of retropie, I’ve redone and re-tweak the image files and configs.
aspect_ratio_index = "22" custom_viewport_width = "860" custom_viewport_height = "774" custom_viewport_x = "530" custom_viewport_y = "153" input_overlay_enable = true input_overlay = /opt/retropie/configs/gb/overlay/gb1080p_grid.cfg input_overlay_opacity = 1.0 input_overlay_scale = 1.0
