Byte-verified reverse engineering reveals FFIX ocean uses only 3 shades across 3,583 tiles.

Strengths
  • Days of byte-level archaeology recovered rotation data that naive reconstruction missed.
  • Interactive demonstrations let readers slide between textures and shade maps.
  • Measured adjacency rules prove Sea3 and Sea4 never touch—Sea5 always bridges.
Weaknesses
  • Niche audience—only matters if you care about PS1 graphics or Wang tiles.
  • Single-game analysis limits broader applicability of the technique.
