What is a .YYP file?
YYP is a GameMaker Studio project file. Created by YoYo Games.
- Did you know
- GameMaker is a popular engine for 2D games, and YYP is its project format.
- The .yyp sits at the root of a GameMaker project and lists every resource plus project-wide settings, acting as the index the IDE loads first.
- It is accompanied by a separate “.resource_order” file that records the custom ordering of assets shown in the editor’s resource tree.
- What Analyser reads
- Identify and read more game and emulator files: Unity asset bundles, Unreal cooked assets, CISO/CHD disc images, FMOD/Wwise sound banks, Spine skeletons and atlases, GameMaker/LDtk/TIC-80 projects, Minecraft Anvil regions, Warcraft III maps, Ren Py and RPG Maker data, extra console ROMs (Atari, PC Engine, Master System/Game Gear, WonderSwan, 3DS homebrew), xdelta/Basis patches and emulator saves and movies.
- Depth of analysis
- .YYP is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .YYP file
- Drag a .YYP file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
