## Compression
The repository supports using DEFLATE compression instead of Nintendo's Yay0. This boasts a better compression ratio, but at a slight cost to load times.
The repo also supports RNC (Rob Northen Compression). RNC has two methods.
Method 1 is designed to compress as small as possible, while method 2 is designed so that decompression is as fast as possible.
Method 1 is the current default, and is the best all-rounder in terms of speed and ratio.
Both methods are fast. Method 1 has better compression than 2, so I suggest using method 1 if using RNC.
To switch to RNC, run make with either ``COMPRESS=rnc1`` or ``COMPRESS=rnc2``, depending on preferred method.
The repository also supports using DEFLATE compression. This boasts a better compression ratio, but at a slight cost to load times.
On average I'd estimate that the bottleneck on decompression is about 1-2 seconds.

The repo also supports gziping with ``libdeflate-gzip``. This compresses at a slightly better ratio than standard ``gzip``, with no real downside from a decompression standpoint.
To use ``libdeflate-gzip``, first clone the [repo](https://github.com/ebiggers/libdeflate), then make and make install it.

The repo also supports building a ROM with no compression.
This is not recommended as it increases ROM size significantly, with little point other than load times decreased to almost nothing.
