• Variable Reuse: Cleverly reusing variables for different purposes at different game stages

Graphics Optimization

Creating smooth graphics on limited hardware requires several optimization techniques:

• Sprite Reuse: Using the same graphic elements in multiple contexts
• Dirty Rectangles: Only redrawing portions of the screen that have changed
• Color Palette Tricks: Using limited color palettes effectively for visual impact
• Animation Frames: Carefully managing animation frames to maintain performance

Input Handling

Casio calculators have limited input options, typically just the keypad. Creative input schemes include:

• Key Combinations: Using simultaneous key presses for complex controls
• Menu Systems: Implementing context-sensitive menus
• Gesture Recognition: On touchscreen models, implementing simple swipe gestures
• Timed Input: Using the duration of key presses for different actions
