Details on overlays here:
Automatic Tool to apply them here:
I am running this on a 720p TV, with CEA mode 4 set when I start the game (by pressing x as it boots).
Contents of /opt/retropie/configs/gb/retroarch.cfg
Code: Select all
video_shader_enable = true
video_shader = /opt/retropie/emulators/retroarch/shader/bead.glsl
input_overlay_enable = true
input_overlay = /opt/retropie/emulators/retroarch/overlays/gb.cfg
input_overlay_opacity = 0.70 # 1.0
input_overlay_scale = 1.0
aspect_ratio_index = "22"
custom_viewport_width = "432"
custom_viewport_height = "389"
custom_viewport_x = "423"
custom_viewport_y = "165"
The width and height above were chosen to keep the aspect ratio of 160x144 of the original - so I presume I need to keep the ratio anyway.
The x and y determine where the top left corner of the screen should start.
