PAK (File Format)
The .pak format is a packfile format; some variation of it is used in every Retro Studios game to contain the bulk of the game's assets. There are three pak formats:
- PAK (Metroid Prime) is used in Metroid Prime and Metroid Prime 2.
- PAK (Metroid Prime 3) is used in Metroid Prime 3 and Donkey Kong Country Returns.
- PAK (Tropical Freeze) is used in Donkey Kong Country: Tropical Freeze.
