Resources for Style

  • https://www.copetti.org/writings/consoles/nintendo-ds/#graphics
  • DS graphics are similar to N64 and PS1 graphics but 3D models are more refined. A good example is Mario in Super Mario 64 vs Mario in Super Mario 64 DS. 
  • The DS had cell shading for 3D rendering and only had enough memory for roughly 2048 triangles 
  • The DS could only do 30 FPS if 3D was on both screens
  • The DS had an 18-bit RGB color palette being able to display 262,144 colors but only 32,767 at a time
  • The 3DS had a 24-bit RGB palette
  • The 3DS is similar to PS2/Gamecube/Wii graphics in terms of power and uses
  • For creating a optional 3d rendering effect (if you're doing a 3DS style game) see if your game engine/tool of choice has a Anaglyph 3D post process
  • Each screen on the DS was 256 x 192 pixels
  • The 3DS's bottom screen was 320 x 240 pixels with the top being 800 x 240 pixels but was effectively 400 x 240 pixels
  • If you know any other resources please post them in community tab!
  • This is not necessary for the jam but if you want to do hombrew (running the game on hardware/ in an emulator) look into libnds for the ds and libctru for the 3ds

Get the Word Out!

Similar to the N64/PS1 style the DS/3DS style have a lot of potential but are under utilized. Help the style spread and share a link to the jam: www.itch.io/jam/dual-screen-jam-3

Most Importantly!

Have fun!

Hope you have an awesome day!
