|
||||
1) Introduction
|
||||
===============
|
||||
|
||||
UIF2ISO is an open source command-line/GUI tool for converting single
|
||||
and multipart UIF images to the original ISO format.
|
||||
It's released under the GNU GPL license and its source code is
|
||||
available in the src folder.
|
||||
|
||||
The UIF image (Universal Image Format, although there is nothing of
|
||||
"universal" in it) in fact is just a compressed CD/DVD image created
|
||||
through a commercial program called MagicISO.
|
||||
|
||||

======================================
|
||||
2) Shame on MagicISO and GPL violation
|
||||
======================================
|
||||
|
||||
The chinese program called MagicISO has created the UIF format in the
|
||||
2006 and, exactly like PowerISO already did at the beginning of that
|
||||
year, this format has been slowly started to be used to re-diffuse
|
||||
copyrighted material through BitTorrent... with the right effect that
|
||||
anyone hates this format (which is totally useless and, being closed,
|
||||
it should be NOT used on file sharing networks).
|
||||
|
||||
This is a shameful marketing strategy made by the same author of
|
||||
MagicISO (a certain Gang JiaPing) for forcing the users who download
|
||||
these torrents to buy and use his program.
|
||||
|
||||
These facts have been confirmed just recently due to the introduction
|
||||
of various senseless encryption mechanisms in the UIF files released
|
||||
on BitTorrent, all encryptions which have nothing to do with the UIF
|
||||
format but have been inserted only for trying to avoid the usage of my
|
||||
uif2iso alternative... without success 8-)
|
||||
|
||||
For example the recent 5.5.272 version of MagicISO has introduced well
|
||||
"8" customized encryption algorithms plus other modifications JUST
|
||||
with the target of making the UIF format unreadable (again without
|
||||
success, look at uif2iso 0.1.6) and has also introduced support for
|
||||
the DAA image format.
|
||||
Unfortunately most of the code used by MagicISO for handling the DAA
|
||||
format has been "taken" from my other open source daa2iso tool
|
||||
violating my GPL license and showing how much ehmmmm "unprofessional"
|
||||
is the author of that program:
|
||||
|
||||
http://aluigi.org/misc/magiciso_gpl_violation.txt
|
||||
|
||||
Luckily that code which was copied was old and not compatible with the
|
||||
newer versions of the DAA format so it fails to handle these files
|
||||
correctly.
|
||||
|
||||
My best suggestion is to spread the voice about the shameful actions
|
||||
of MagicISO and its author and avoiding to download or keep the
|
||||
seeding of torrents of UIF or DAA images.
|
||||
|
||||
And remember that uif2iso has been created only for supporting the UIF
|
||||
format and *NOT* for playing "cat and mouse" with an idiot who
|
||||
modifies this stupid zipped format each time for becoming the only
|
||||
program able to read it...

|
||||
3) Usage on Windows
|
||||
===================
|
||||
|
||||
Using UIF2ISO on Windows is really a joke, just double click on
|
||||
UIF2ISO.exe and the tool will open a DOS-like window which contains
|
||||
all the needed informations about the status of conversion, then you
|
||||
will need to choose the input UIF file you want to convert and
|
||||
subsequently the name of the output file you want to create.
|
||||
|
||||
Note that the correct extension (ISO, NRG or BIN/CUE and so on) is
|
||||
automatically selected by the tool depending by the input UIF file.
|
||||
|
||||
If you want to use the tool from the command-line, so specifying the
|
||||
input and output files manually as in the older versions of the tool,
|
||||
you can do it too since UIF2ISO automatically recognizes if it has
|
||||
been launched from the console (cmd.exe) or through double-click.
|
||||
Just specify the input UIF file and the output ISO file you want to
|
||||
create like in the examples of the subsequent section.
|
||||
|
||||
Remember that you can also associate the UIF extension to UIF2ISO, so
|
||||
when you will double-click on these files UIF2ISO will popup and will
|
||||
allow you to choose the output file immediately or you can also
|
||||
drag'n'drop the UIF file directly on UIF2ISO.EXE.
|
||||
|
||||
Note that UIF2ISO is a stand-alone program, so all you need to have is
|
||||
only UIF2ISO.EXE and you can place it everywhere you want.
|
||||
|
||||
|
||||

|
||||
4) Usage on *nix/MacOSX
|
||||
=======================
|
||||
|
||||
Compile the source code using 'make', this will generate the UIF2ISO
|
||||
executable.
|
||||
If you want to install it type 'make install' or just copy the
|
||||
executable where you want since it's the only file you need.
|
||||
|
||||
The only requirement for compiling and using UIF2ISO is zlib
|
||||
(apt-get install zlib1g zlib1g-dev).
|
||||
|
||||
Using it then it's simple, just specify the input file and the ISO
|
||||
file you want to create like the following example:
|
||||
|
||||
uif2iso "my file.uif" output.iso
|
||||
|
||||
|
||||
######################################################################
|
||||
|
||||

|
||||
5) Features and known bugs
|
||||
==========================
|
||||
|
||||
The tool supports password/encryption, little/big endian architectures
|
||||
and should work on many platforms (Windows, Linux, MacOS, *BSD, Amiga
|
||||
and others).
|
||||
|
||||
The NRG file (compressed UIF) created by MagicISO is invalid so,
|
||||
although my tool tries to fix some fields and generates an additional
|
||||
CUE file, is possible that the resulted image isn't fully recognized
|
||||
by the burning/mounting program you want to use.
|
||||
During my tests I have found (only one time) also an invalid output
|
||||
ISO file (the uif was decompressed with both uif2iso and MagicISO)
|
||||
which was possible to read correctly only through MagicISO... it's
|
||||
useless to say that is a shame since creating non-standard images is
|
||||
an INTENTIONAL action made by the MagicISO's programmer!!!
|
||||
|
||||
A known micro-bug is that on Windows 95/98/ME works only the so
|
||||
called GUI version because the trick I use to know if the program has
|
||||
been launched from the console or through double-click is not
|
||||
compatible with this OS, anyway this is not a problem because the 99%
|
||||
of the Windows users don't like the command-line 8-)
|
||||
|
||||
I'm available for any comment or feedback, so if you find a
|
||||
compatibility problem with a specific UIF image (and you are sure that
|
||||
the image is perfect) send me a mail!!!
|
||||

|
||||
6) Technical info about the format
|
||||
==================================
|
||||
|
||||
UIF2ISO is open source so there is nothing better than its source code
|
||||
for explaining in detail this file format and for updates.
|
||||
|
||||
In short UIF is a compressed disk image which can be derived by 5 or
|
||||
more types of input images:
|
||||
- ISO: only the classical data
|
||||
- BIN/CUE: data, audio or mixed content
|
||||
the UIF file contains a BLMS section with raw CUE informations
|
||||
(UIF2ISO uses them to generate the relative CUE file) and a BLSS
|
||||
field containing the original CUE file used by who created the UIF
|
||||
- MDS/MDF: Alcohol 120%'s proprietary disk image format
|
||||
- CCD: CloneCD image
|
||||
- NRG: disk image in Nero v2 format
|
||||
unfortunately for some reasons which I don't know the "UIFed" NRG
|
||||
image generated by MagicISO is invalid (these images don't work with
|
||||
other programs included Nero which is the creator of the NRG
|
||||
format!) and although my UIF2ISO fixes some of these fields is still
|
||||
possible that with some type of images the fixed NRG could not work
|
||||
since not 100% compatible.
|
||||
Another work-around I have adopted is the generation of an
|
||||
additional CUE file derived from the NRG one which in my test worked
|
||||
perfectly with data, audio and mixed CDs and partially with CD
|
||||
extra.

7) Comments about the UIF format
|
||||
================================
|
||||
|
||||
I don't like and don't approve the UIF format because it's proprietary
|
||||
and doesn't give benefits.
|
||||
What you can do with UIF can be done better with ZIP or 7zip without
|
||||
the need to be forced to buy a software like MagicISO only for burning
|
||||
or converting a CD/DVD image.
|
||||
|
||||
Ok exists my tool which can do the job but this is not a valid reason
|
||||
to continue to use this useless format.
|
||||
|
||||
So if you want to create a CD/DVD image, DO NOT USE UIF!
