PS1 Sprite Tiling Debug Log

docs/archive/PS1_TILE_RENDERING_DEBUG.md

This is the website shelf page for docs/archive/PS1_TILE_RENDERING_DEBUG.md. It exists because the project has hundreds of Markdown files and the website should not pretend the interesting work only happened in the polished essays.

Why this file matters

Historical archive. This is older project documentation preserved for context. It is not the current source of truth, but it explains the roads that were tried.

JOHNWALK.BMP sprites are 64x78 pixels - 14 pixels taller than the PS1’s 64-pixel texture limit. Johnny’s feet are cut off because only the top 64 rows are loaded/rendered.
