Not licensed by Nintendo

Game Boy startup logo animation.

This is my first Game Boy project ever. The code is pure assembly and the art is hand-painted.

The demo consists of three separate scenes:

1. Not licensed by dropping from above.
2. ® falling down.
3. Everything flying away.

Platform-Specific Features

• Game Boy Colour: B&W palette, multi-colour palettes for Not licensed by, gradient, fade-in, fade-out
• Super Game Boy: B&W palette, fade-in, fade-out
• DMG: grayscale palette for Not licensed by, fade-out
• DMG0: ® is invisible

Flavours

• drop-only (scene 3 removed, much smaller ROM footprint)

Technical Details

The 10 sprite-per-scanline limitation is overcome in the third scene by rendering some of the elements separately:

• by and e on the background (causing them to share the vector of movement) and
• 2nd n on the window.

Building from Source

make

Customisations

The intro provides numerous customisation hooks via defs.inc. Following is a non-exhaustive list:

• INTRO_SONG: hUGETracker song descriptor.
  • Uncomment src/intro/intro_song.o and src/hUGEDriver.o in Makefile (and then replace intro_song with your own song).
  • INTRO_SONG_DELAY: song delay in ticks.
• INTRO_COLOR8: enable multi-coloured top letters on GBC/DMG.
  • C_INTRO_TOP: default top letters' colour.
  • C_INTRO_TOP_n: (0 <= n <= 7): n-th top letter colour.
  • C_INTRO_BY: default by letters' colour.
    • C_INTRO_BY1: b letter colour.
    • C_INTRO_BY2: y letter colour.
  • INTRO_COLOR8_DMG: enable grayscale top letters on DMG.
• INTRO_GRADIENT: enable background gradient on GBC.
  • C_INTRO_GRADIENT_TOP: gradient's top colour.
  • C_INTRO_GRADIENT_BOTTOM: gradient's bottom colour.
• INTRO_FADEOUT: enable fadeout on GBC/SGB.
  • INTRO_FADEOUT_DMG: enable fadeout on DMG.
• EN_GB: display licenced instead of licensed.

Common colour values are defined in color.inc.

After changing Makefile make sure to execute

make clean all

Note: Uncommented lines that are part of a Makefile multi-line definition must not be preceded by commented-out ones.
