📄 Description

What: Dead Cells (Steam macOS, build 35): a field note on a clean-room libGDX rebuild of the first biome that reads every asset from the user's own res.pak at runtime.

The note covers:

Formats: the PAK (Dead Cells' 64-byte stamp variant), BATL atlas, BTMX room template and CastleDB layouts, written in my own words.
Rendering: hero pages are palette-indexed (red = column, green×4 = row of <model>_<skin>_s.png). Mob pages are flat colour with a magenta glow key. Level tiles are black albedo, with _n normal maps and biome gradients providing the look.
Sound: every .wav in the pak is actually Ogg Vorbis.
Movement: with the documented jump numbers the hero only reaches about 3.5 cells, so some template pits need the jump-through-up and ledge-grab assists to escape.
Gotchas: 7 numbered ones (symptom → cause → fix), plus what was and wasn't verified.

Checklist

um kb check passes (field notes)
um kb index regenerated (field notes)
no game files, extracted assets, decompiled code dumps or secrets
nothing that cheats other players or bypasses anti-cheat / DRM / ownership checks
versions, verification and what was NOT verified are written down
