Chunk Types

BEAN: file signature

HEAD: contains 10-byte payload including unknown 16-bit quantity and 32-bit width and height stored as little-endian

RGBS: palette triplets; payload should be 0x300 (768, 256x3) bytes long; values range from 0..255; must be a constant length since it has no provision for palette replacement

SFXB..WRAP..OFFS: apparently a setup for audio data

DATA: audio or video data; audio data is 8-bit, unsigned PCM

BLOK: video data block?

SRLE: apparently the video compression type, possibly based on lzss.c

SNDE: reference into audio data?
