Install xmame from source on Debian Linux 7.0 (Wheezy) to play for better MAME (Arcade Games Emulation)

Thursday, May 30th, 2013

xmame logo install xmame on latest stable debian

Whether you're keen on playing old school arcade games. And you just updated or installed latest stable Debian 7 Wheezy. You will find out current installable Mame (Arcade Emulator) package cannot play many of the hot Games, even though game rom files are okay and you might have played those games in some previous versions of Debian with now obsolete but apparently better working emu  xmame.

As playing Captain Command, Xain'D Sleena, Cadillac & Dinosaurs and Punisher Classic Arcades is one of my great entertainments when I have some free time. I took the time to find out if xmame is still installable either by deb package or from source.

Unfortunately xmame for latest Debian releases is not available from unofficial repositories, so I proceeded with installing it from source. Thanksfully source install was successful. Hence, below is explained how to install xmame from source on Debian Wheezy and Debian testing/unstable.
First before compiling install a bunch of development packages necessary for proper compilation:

# apt-get install --yes zlib1g-dev
# apt-get install --yes libexpat1-dev
# apt-get install --yes libghc-x11-dev
# apt-get install --yes x11proto-video-dev
# apt-get install --yes libxv-dev

Download xmame 0.103 source archive (xmame-0.103.tar.bz2)

Tar archive doesn't have configure script so to compile it just run make ;

# cd /usr/local/src
# tar -jxvvf xmame-0.103.tar.bz2
# su hipo
cd xmame-0.103
$ make
...
....
$ exit
# make install
.....


In case some header .h file is still missing and compile fails, as it happened to me on few occasions. You can install and use apt-file;

One important note is xmame's build will take very long on my machine with 2Gb of Memory and Dual Core 1.8 Ghz it took about 1,.30 or 2 hours. 

# apt-get –yes install apt-file
# apt-file update

To find from which package the the missing .h file can be installed

# apt-file search Header-Name.h

Then just install package which will provide needed header.

Next step is to create xmame config file:
# mkdir /usr/local/share/xmame/
xmame-0.103$ cp -rpf ./src/unix/doc/xmamerc.dist /usr/local/share/xmame/xmamerc

In xmamerc set proper location for Mame ROM files:

# vim /usr/local/share/xmame/xmamerc
Find line;

rompath                 /usr/local/share/xmame/roms

and change it to whether Rom files are located. In my case they're in /disk/Games/Mames/roms, so change rompath to;
 

rompath                 /disk/Games/Mames/roms

There are some other configurations which you might want to tune. A well configured xmamerc that works fine for me is here

Finally link xmame.x11 to /usr/bin/xmame

# ln -sf /usr/local/bin/xmame.x11 /usr/bin/xmame

After having properly configured XMamE'S roms Directory to launch a game, for example punisher.zip or captcomm.zip:

$ xmame punisher
....
 $ xmame captcom
....

I've build xmame from source on Debian but I suppose same guide should be working okay on Ubuntu, Mint and rest of Debian distributions. I'll be happy to get feedback if someone succeeded running xmame on other distro. If you do please drop me a comment with distro name and specifics or problems faced.

How to crack password protected rar and 7z files on GNU / Linux

break / crack password protected rar, zip archives on Linux and FreeBSD rarcrcack

RarCrack is able to crack rar and 7z archive files protected by password on Linux.
The program is currently at release version 0.2, so its far from perfection, but at least it can break rars.

RarCrack is currently installable on most Linux distributions only from source, to install on a random Linux distro, download and make && make install . RarCrack’s official site is here, I’ve mirrored the current version of RarCrack for download here . To install rarcrack from source using the mirrored version:

linux:~# wget http://www.pc-freak.net/files/rarcrack-0.2.tar.bz2
...
linux:~# tar -jxvvf rarcrack-0.2.tar.bz2
linux:~# cd rarcrack-0.2
linux:~/rarcrack-0.2# make
...
linux:~/rarcrack-0.2# make install
...

On FreeBSD, rarcrack is available and installable via the ports tree, to install on FreeBSD:

freebsd# cd /usr/ports/security/rarcrack
freebsd# make && make install
...

To use RarCrack to crack rar, zip or 7z archive file:

freebsd% rarcrack rar_file_protected_with_password.rar --type rar

The argument –type rar is optional, in most archives RarCrack should detect the archive automatically. The –type option could also take the arguments of rar and 7z .

I’ve created a sample rar file protected with password linux_then_and_now.png.rar . The archive linux_then_and_now.png contains a graphic file illustrating the linux growth in use in computers, mobiles and servers. linux_then_and_now.png.rar is protected with the sample password parola

RarCrack also supports threads (a simultaneous instance spawned copies of the program). Using threads speeds up the process of cracking and thus using the –threads is generally a good idea. Hence a good way to use rarcrack with the –threads option is:

freebsd% rarcrack linux_then_and_now.png.rar --threads 8 --type rar
RarCrack! 0.2 by David Zoltan Kedves (kedazo@gmail.com)
INFO: the specified archive type: rar
INFO: cracking linux_then_and_now.png.rar, status file: linux_then_and_now.png.rar.xml
Probing: '0i' [24 pwds/sec]
Probing: '1v' [25 pwds/sec]

RarCrack‘s source archive also comes with three sample archive files (rar, 7z and zip) protected with passwords for the sake of testing the tool.
One downside of RarCrack is its extremely slow in breaking the passwords on my Lenovo notebook – dual core 1.8ghz with 2g ram it was able to brute force only 20-25 passwords per second.
This means cracking a normal password of 6 symbols will take at least 5 hours.
RarCrack is also said to support cracking zip passwords, but my tests to crack password protected zip file did not bring good results and even one of the tests ended with a segmentation fault.

To test how rarcrack performs with password protected zip files and hence compare if it is superior or inferior to fcrackzip, I used the fcrackzip’s sample pass protected zip noradi.zip

hipo@noah:~$ rarcrack --threads 8 noradi.zip --type zip
2 by David Zoltan Kedves (kedazo@gmail.com)
INFO: the specified archive type: zip
INFO: cracking noradi.zip, status file: noradi.zip.xml
Probing: 'hP' [386 pwds/sec]
Probing: 'At' [385 pwds/sec]
Probing: 'ST' [380 pwds/sec]

As you can see in above’s command output, the zip password cracking rate of approximately 380 passwords per second is a bit quicker, but still slower than fcrackzip.

RarCrack seg faults if cracking a pass protected zip is passed on without specifying the –type zip command arguments:

linux:~$ rarcrack --threads 8 noradi.zip
RarCrack! 0.2 by David Zoltan Kedves (kedazo@gmail.com)
Segmentation fault

While talking about cracking protected rar and zip archives with password, its worthy to mention creating a password protected archive with Gnome Desktop on Linux and FreeBSD is very easy.

To create the password protected archive in Gnome graphic environment:

a. Point the cursor to the file you want to archive with password

Gnome pointing file properties drop down menu

b. Press on Other Options and fill in the password in the pwd dialog

Linux protect rar with password on Gnome Desktop

I think as of time of writting, no GUI frontend interface for neither RarCrack or FcrackZip is available. Lets hope some good guy from the community will take the time to write extension for Gnome to allow us to crack rar and zip from a nice GUI interface.
