Computers Are Easy, Love Is Kind [NES demo]

Computers Are Easy, Love is Kind is an NES demo that demonstrates video glitching, basic music, sprite animation, user input, and color cycling. The ROM was made in one day, on the occasion of the US Supreme Court ruling on marriage equality (June 26, 2015). Fully-commented 6502 ASM source code and updates to the sparkle animation were released on September 11, 2015.

Playing the ROM: Press up and down to change colors. Press B to toggle glitching. Press A to toggle music visualization (sparkle animation).

Source code: Available on GitHub. Note that the source code is intended to be instructional and illustrative for those learning 6502 assembly for the NES. As such, code for routines is repeated and unrolled, which may read as "inefficient." Efficiency is relative, after all; what is efficient in one context (fewer lines of code) becomes inefficient in another (learning a new programming language/platform). Remember: Computers are easy! Love is kind!
