Alternative Driver Library for Game Development[edit]

There is an alternative driver library (GitHub Page) for v1.3 of MeggyJr RGB. This driver has the following features:

  • Minimal SRAM usage.
  • Display double buffering (no flickering even for slow drawing code).
  • Selectable application frame rate (15, 30, 60 or 120 FPS).
  • Loop to display synchronization.
  • Simple RGB color handling with Color class.
  • Advanced functions like scrolling and fading and sprites.
  • Comfortable button handling.
  • Interrupt based sound player, with notes and effects.
  • Load meter to graphically measure your loop performance or RAM usage.

The library comes with a short documentation overview and has in detail API documentation in the code. It comes with a number of examples to demonstrate most of the features. The game Lucky World demonstrates all features of this library. It is open source (GPL v2), therefor you are invited to study every detail how the game was made.
