Suggestion: Addition of official GB and GBC N3DS VC borders to the shader repository

RetroArch Additions Shaders
#1

User SciresM from the GBAtemp forum published the extracted Game Boy Color border from the Nintendo 3DS Virtual Console in 2014 here.

I made modification to the existing sgb border files to make this border compatible with Retroarch:

gbc.png (320 x 256 px - 5:4 Aspect Ratio - SXGA 1280 x 1024 px integer - Power LED Color: R 255 G 0 B 0):

gbc.cgp:

shaders = "1"
shader0 = "../resources/imgborder-gbc.cg"


scale_type_x0 = "absolute"
scale_x0 = "320"
scale_type_y0 = "absolute"
scale_y0 = "256"


parameters = "box_scale;location;in_res_x;in_res_y;out_res_x;out_res_y"
box_scale = "1.000000"

out_res_x = "320.000000"
out_res_y = "256.000000"

Sadly I haven’t found the original Game Boy border. Maybe someone can provide it? Also this border is not compliant with 240p CRTs, so we could also make a cropped 240p version of the border.

That’s a neat idea. I like it!

It’s only letting me post one image since I’m new, but I took some screenshots on my 3DS using custom firmware of the Gameboy, Game boy Color, and the four different Sega Game Gear borders. Here is the Game Boy one that I cut a hole out of. It has a bit of extra space around the inner game screen that’s the same color as the lightest shade of the current palette, but since that would clash with Retroarch I re-colored it to match the gb-palette-pocket.cgp that retroarch has.
