Wenas chicos!! Pues sà , tal como léeis, ya tenemos disponible lo que parece ser un nuevo formato de compresión para reducir al mà nimo el tamaño de nuestras isos: JSO.
Dicho formato ha sido desarrollado por un usuario de MaxConsole, Uncle Man, y parece que es una mezcla entre DAX y CSO, por lo que por lo visto, reducirà a nuestras isos al tamaño de los DAX e irà a a la velocidad de los CSO.
Aún no he podido probarlo, pero según se comenta, la iso del GTA comprimida a este formato va casi sin ralentizaciones .
Aquà os dejo el post original de Uncle Man en MaxConsole, y la descarga:

Hi guys
I just finished a new version of my former DAX plugin for Devhook 0.46. It's now called JSO & DAX support plugin as it supports DAX and JSO file formats (in addition to ISO and CSO file formats of course).
What is JSO ? JSO is a new file format that intends to achieve faster decompression and/or smaller file size. JSO supports the following
- zlib (as CSO and DAX) and lzo compression. lzo is a bit faster than zlib but files are a bit bigger
- frame size from 2048 (as CSO) to 16384 for better compression
- small memory footprint, thanks to minilzo and kerner zlib decompression library
Howto
=====
As always, just drop the umdciso.prx file in [MP_ROOT]/dh/kd and replace the existing file.
You will find three folders:
- full/umdciso.prx
Full version with DAX & JSO file support (56 kbytes)
- nodax/umciso.prx
JSO file support, DAX file support removed for a smaller memory footprint (15 kbytes)
- pc/jiso.exe
JSO Compression/Decompression utility. Type jiso.exe -h for help.
Jiso ISO9660 converter Ver.1.00 by Uncle Jam
Usage: jiso.exe -c|d [-s] [-a algorithm] [-b size] [-l level] [-t threshold] -i
inputfile -o outputfile
-h : This help page
-c|d : Compress | Decompress
-s : Simulation mode enabled
-a algorithm : Compression algorithm (lzo, zlib), default is lzo.
-b size : Block size (2048, 4096, 8192, 16384), default is 2048
-B : Block header mode enabled (faster decompression)
-l level : Compress level (1=fast/large - 9=small/slow), default is 9
-t threshold : Compress threshold (0.0 - 1.0), default is 1.0
-i inputfile
-o outputfile
Note : The -B option has shown pretty bad results so far. You should not use it.
Please post here any comments.
As for last time, source code will be released with final version
Have fun
