++.Dt MAXCSO 1
++.Os
++.Sh NAME
++.Nm MAXCSO
++.Nd Fast cso compressor
++.Sh SYNOPSIS
++.Nm maxcso
++.Op Fl -args
++.Op Ar input.iso
++.Op Fl o Ar output.cso
++.Sh DESCRIPTION
++A fast ISO to CSO compression program for use with PSP and PS2 emulators, which
++uses multiple algorithms for best compression ratio.
++.Ss FEATURES
++.Bl -bullet -offset <TAB> -compact
++.It
++Can use as many CPU cores as you want.
++.It
++Can use
++.Xr zlib 3 ,
++7-zip's deflate, and Zopfli.
++.It
++Processes multiple files in one command.
++.It
++Can take a CSO or DAX file as a source.
++.It
++Able to output at larger block sizes.
++.It
++Support for experimental CSO v2 and ZSO formats using
++.Xr lz4 1
++(faster decompression).
++.It
++Tuning of deflate or
++.Xr lz4 1
++compression threshold.
++.It
++Decompression of all supported inputs (including DAX and CSO v2).
++.El
++.Ss Compression
++.Nm maxcso
++always uses compression level 9.
++Decompression speed is about the same regardless of level, and disk access is
++faster with smaller files.
++.Pp
++Using 7-zip's deflate and Zopfli improves compression ratios, but don't expect a
++lot.
++Usual results are between 0.5% to 1.0% smaller.
++.Pp
++Larger block sizes than the default will help compression, in the range of 2-3%.
++However, the files may not be compatible with some software.
++For example,
++.Nm ppsspp
++versions released after 2014-10-26 will support larger block
++sizes.
++.Pp
++Avoid DAX where CSOs using larger block sizes are supported, since DAX is less
++efficient.
++.Pp
++.Xr lz4 1
++support is mostly for experimentation.
++.Ss Speed
++Compared to other tools like ciso and CisoPlus,
++.Nm maxcso
++can run much faster and achieve the same compression.
++Use
++.Fl -fast
++to get the fastest compression, which matches level 9 in other tools.
++.Pp
++Additionally, if you have better than a dual core processor,
++.Nm maxcso
++will use all
++of your cores, and perform even better.
++.Pp
++In usage, CSOs typically perform well in all known emulators.
++Some versions of PSP firmware with
++support for CSOs have bugs in their CSO support, but this doesn't affect
++emulators.
++.Sh OPTIONS
++Multiple files may be specified.
++Inputs can be iso or cso files.
++.Bl -tag -width indent
++.It Fl -threads=N
++Specify N threads for I/O and compression.
++.It Fl -quiet
++Suppress status output.
++.It Fl -crc
++Log CRC32 checksums, ignore output files and methods.
++.It Fl -fast
++Use only basic
++.Xr zlib 3
++or lz4 for fastest result.
++.It Fl -decompress
++Write out to raw ISO, decompressing as needed.
++.It Fl -block=N
++Specify a block size (default depends on iso size).
++Many readers only support the 2048 size.
++.It Fl -format=VER Ar cso1 , cso2 , zso , dax
++Specify cso version.
++These are experimental, default is
++.Ar cso1 .
++.It Fl -usr-zlib
++Enable trials with
++.Xr zlib 3
++for deflate compression.
++.It Fl -use-zopli
++Enable trials with Zopfli for deflate compression.
++Because Zopfli is significantly slower than the other methods and uses a lot
++more memory, it is disabled by default.
++Use for maximum compression.
++.It Fl -use-7zdeflate
++Enable trials with 7-zip's deflate compression.
++.It Fl -use-lz4
++Enable trials with lz4hc for
++.Xr lz4 1
++compression.
++.It Fl -use-lz4brute
++Enable bruteforce trials with lz4hc for
++.Xr lz4 1
++compression.
++.It Fl -only-METHOD
++Only allow a certain compression method (
++.Xr zlib 3 ,
++etc. above).
++.It Fl -no-METHOD
++Disable a certain compression method (
++.Xr zlib 3 ,
++etc. above).
++.It Fl -lz4-cost=N
++Allow
++.Xr lz4 1
++to increase block size by N% at most (cso2 only).
++.It Fl -orig-cost=N
++Allow uncompressed to increase block size by N% at most.
++.El
++.Pp
++The cost arguments allow you to allow each block to be N% bigger by using
++.Xr lz4 1
++or no compression.
++This makes the file read faster (less cpu power), but take more space.
++.Sh EXAMPLES

++.It Nm maxcso Ar myfile.iso Fl o Ar output.cso
++Compress
