# AArcade Cross-Compatibility Specifications

## Purpose
This document defines the tiers of cross-compatibility AArcade can achieve across multiple games/engines/platforms.

It defines the list of art assets expected to be supported at each tier, and also the logic/functionality at each tier.

This document is expected to be used as a reference when creating AArcade clients on other games/engines/platforms, or when a 3rd party project wishes to add cross-compatibility with AArcade.

### Simple Tier
- Just support MSF structed meta data items, usually as JSON files.
- Nothing like 3D models or object positions, just media item import/export.
- Can import/export media libraries, but cannot save/load 3D saves that are cross-compatible.

### Full Tier
- Support MSF items AND support a short list of 3D objects and environments by porting them to your game.
- This will allow cross-loading of saves created on any AArcade client.
- Multiplayer can also be implemented between any 2 cross-play clients that wish to integrate it. (As AArcade: Source and AArcade: PlayCanvas will.)
