Category: Art / noise generator
Version: Beta (3)
Made in: Amaranth HDL
Spiciness: 🌶️🌶️
WARNING: Can make high-pitched sounds

Turn off "Frame blending" when using this core.

Controls:

• D-pad UP: Select Rule 30 (Equilateral triangles)
• D-pad LEFT: Select Rule 110 (Turing-complete triangles, leaning left)
• D-pad RIGHT: Select Rule 106 (Sierpenski triangles, leaning right)
• D-pad DOWN: Select Rule 14 (Shift left)
• L and R: Speed down/up
• Y: Hold to draw black pixels
• X: Hold to draw white pixels
• B: Hold to draw black pixels (many)
• A: Hold to draw white pixels (many)
• Start: Pause
• Select: Hold this and press another button to make it "single-frame"; for example while paused hit select-start to iterate one frame, or select-Y to insert one black pixel on a single frame.

• Color: Select a pure black and white, pink and orange, purple and green, or dark blue color scheme
• Rule (up, left, right, down): Select the CA rule. I recommend doing this while paused. Defaults are 30, 110, 106, 14, but some other numbers I like are: 26, 90, 45, 109, 113.

Fungus

Organically expanding colors and gurbling sound

Category: Art / noise generator
Version: 1.0
Made in: C (using agg23's Pocket RISC-V core)
Spiciness: 🌶️

This was written as quick and dirty sample code for Pocket RISC-V but it turned out quite nice, especially if you let it run for a while. A thing I like doing is hitting the X and A keys at once right after it boots.

Controls:

• D-pad: Push fungus
• L and R: Adjust colors
• A: Toggle fast color cycle
• B: Toggle between 3 growth speeds
• X: Toggle Super Grow
• Y: Toggle Dense Grow
• Select: Pause
• Start: Restart

Based on a program I wrote by accident when I was 18.

Controls

• D-pad LEFT and RIGHT: Zoom in/out

Uses the hilbert_2d library by Humberto Duarte.

Minibreak

Minimal (and very difficult) brick break game

Category: Game
Version: 1.0
Made in: Rust (using agg23's Pocket RISC-V core)
Spiciness: 🍞

This is an early prototype of another game I'm making. I got to the point of things moving and filling in collision rectangles and realized I'd legally fulfilled all the requirements of a "video game", so I decided to release it as Pocket RISC-V sample code. Since it is so simple, the only way I could make it interesting at all was to make it absurdly difficult. If you can win this you are a super player

Controls:

• D-pad LEFT and RIGHT: Move
• Select: Pause
• Start: Restart
