To target iQue, run make with the ``CONSOLE=bb`` argument.
## 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.
To switch to gzip, run make with the ``COMPRESS=gzip`` argument.
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.
To switch to no compression, run make with the ``COMPRESS=uncomp`` argument.
