What Is an RSPS Cache?

What the cache does

A game cache stores data a client uses to present and interpret the game world. Depending on the build, this can include models, maps, interface assets, animations and item definitions. The precise format and content depend on the client.

It is not the same thing as the server’s character storage. Replacing asset files is not a normal method of transferring a player’s account or progress.

Assets do not implement gameplay

An item can exist as a model and definition without its special effect, drop source or quest being implemented on a server. That is why a visible interface or recognisable object is not proof of a completed feature.

Client, cache and server code must agree on identifiers and behaviour. Mixing data from unrelated builds can produce incorrect graphics, missing interfaces or more serious compatibility problems.

Preservation and provenance

The OpenRS2 Archive describes its collection as covering JS5-era asset systems and their precursor. Its documentation explains how matching checksums and version information help combine compatible preserved data.

For historical research, retain the exact archive entry, source and build information. “An old cache” is not enough to establish which game version an artifact represents.
