Thread: Packing OSRS regions/maps to 667?

Here's a hands-on guide suitable for people with little to no knowledge on the different RS cache formats:

First off you need a cache library that supports both caches (the one you're trying to pack FROM, and the cache you're trying to pack TO). This is easily found by downloading 500+ revision servers. They mostly support the same revisions (450~ to 650~) and they pretty much all depend on a cache library to read data.

In this cache library, you're going to be looking for methods used to read data from the cache. Usually looks something like this:

Code:

byte[] file_data = cache.getIndexes()[x].getArchive(y).getFile(z);

Now, as you can see, the code is pretty self-explanatory.

What you're going to do is make 2 new cache (usually called Store) instances. It will look something like this:

Code:

Store cache = new Store("path to cache here");

The cache library usually not only contains methods to read the data, but also writing data.
Usually looks something like this:

Code:

cache.getIndexes()[x].putArchive(x);

And to finish it off, here's how it could be used to pack a model from an OSRS cache, to a 530 cache.

Code:

cache_530.getIndexes()[7].putArchive(model id, cache_osrs);

Before you go nuts using the cache library, I highly suggest you read through the cache library to see what is actually going on. This way, you'll learn how to support whatever revision of cache & data you want. Compare, compare & compare. Reference data is ALWAYS available in the client.

Here's some information about the different cache formats:

Obviously - to actually use the data is a different story. My post was just an introduction to actually edit the cache.
