Rules

• You must pick if you're doing a DS or 3DS style game
• Your game must be in the style of DS or 3DS game:
  • That means using the DS/3DS control scheme (D-Pad, X, A, Y, B, select, start, right and left bumpers, touch screen, circle pad(s) for 3D)
  • Have 2 different viewports (screen)
    • For the DS the viewport should be 256 x 192 pixels (or scaled)
    • For the 3DS the top viewport should be 400 x 240 pixels with the bottom being 320 x 240 pixels (or scaled)
    • These can be flipped on their side
• You can use any game engine or tools you want
• Teams of any size are allowed
• Submissions that are not SFW (safe for work) must be marked as so
• The theme must be incorporated
• Premade assets can be used but need to be credited
• Your game just has to be in the style of a 3DS/DS game it doesn't actually need to run on either of them :)

Rating

• Style - Does the game feel like a DS or 3DS game?
• Art - How does the game look visually?
• Gameplay - How fun/enjoyable is the game?
• Audio - Is the audio good/does it work with the game?
• Theme - How well does the game incorporate the theme?

Additional Resources for Style

• https://www.copetti.org/writings/consoles/nintendo-ds/#graphics
• 3D DS graphics are similar to N64 and PS1 graphics but 3D models are more refined (due to 3D modelers getting better). 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 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 (Here's an example of how to program it anaglyph-3d-shaders)
• 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
