Audio: all 64 song table entries (59 unique sequences), all 33 BRR instrument samples, original loop/pitch/ADSR/instrument tables. Raw sequence payloads are editable hexadecimal JSON plus original bytes. This export does not synthesize a soundtrack or implement the SPC sequencer.

UI: original planar pixels in indexed PNG atlases plus raw bitplanes. The neutral grayscale PNG palettes are inspection palettes, NOT verified game display colors. Tile ordering is the original ROM ordering; assembly, text glyph mapping and in-game palette selection still need decoding.

Title: two verified LZ77 blocks (original title program and tile placements) are retained both compressed and decompressed. The title background image's separate compression and placement are not decoded here.

The ROM keeps all unexported material. No replacement imagery is included.

The exporter is an independently written Java implementation of these documented formats.
