An archive format used in OHRRPGCE, TAVERN, and possibly other video game engines.

None in general.

A compiled HamsterSpeak program will start with "HS", followed by three null bytes, two variable bytes (these are part of the lump data size; see below), and then the ASCII text "HamsterSpeak".

Description

A Hamster archive consists of zero or more lumps concatenated together (with no delimiters or global header/footer), where a lump consists of the following three parts:

  • Null-terminated ASCII filename
  • PDP-endian 32-bit data size (measured in bytes)
  • Data of this lump
