Zaurus Software

    UCLX is an executable file compressor , for ARM base linux systems.  I wrote it for my Zaurus, but it should work on every ARM linux systems,
like the IPAQ..
It works like UPX on Linux.  Program are compressed, and they transparently decompress on execution. At the cost of a little lost of speed of execution, which is most of the time, unnoticeable...
It give very good compression ratios, in general better than gzip.
For example:
      
zmame executable orig. size    ---> 13.701.876 bytes
compressed with UCLX (level 10)  --> 3.250.162    (23.7 %   of orig. size)

another example ?  ok...

opera executable (the one in the sharp rom) orig.size    -->  2.892.256 bytes
compressed with UCLX (level 10)   -->  1.055.653 bytes   (36.5 % of orig.size)

Decompression is very fast, so you can compress all your executable on your Zaurus to economize your precious RAM...!!

    UCLX compressed file , are first decompressed in  /tmp/  directory,  then the temporary file is deleted while it is executed..
It proceed exactly like UPX do for decompressing executable on Linux, this way has been proven to be stable, well working.
You can set the UCL environnement string, to decompress temporary file to another place, for example in your .bashrc
put-->   set UCL=/mnt/cf/temp/
to decompress temporary file to compactflash instead of /tmp/ dir,  but in general it is not needed...

the syntax to use UCLX is very simple:

for compression:        uclx -z file level      (level is between 1 to 10)
for decompression:   uclx -d file

here is UCLX Zaurus executable:   uclx_arm

here is UCLX x86 executable:   uclx_i386

with the x86 executable you can compress you Zaurus executable, on your computer, which is usefull for big executable that are slow
to compress... then you just transfer them to you Zaurus once compressed...

here is the UCLX source code:  uclx_src.tgz

UCLX and its sourcecode is free, so you can use it in your projects, just send me an email...  (interzone23@free.fr)

    A port of Scummvm last official version v0.4.1 to the Zaurus.
Install the .ipk package, then create whith a text editor, a configuration file named:  .scummvmrc in your home directory,  /home/root/ on the Zaurus.  Set your savepath as you want, I use /mnt/cf/scummvm  for example to put savegames on compactflash.
exemple of  .scummvmrc:

[scummvm]
gfx_mode=normal
fullscreen=true
savepath=/mnt/cf/scumm

then add an entry for each game you have installed, with its path, example:

[zak256]
amiga=false
description=Zak McKracken and the Alien Mindbenders (256)
fullscreen=true
path=/mnt/cf/scumm/zak256/

You then launch, the wanted game, via command line:
scummvm zak256
 or
scummvm -x1 zak256
to launch zak256 & load the first savegame

ipk package --> scummvm_0.4.1_arm.ipk

Here is the patch against ScummVM v0.4.1 sourcecode, to make it compile and work on Zaurus.
Get the standard ScummVM v0.4.1 distribution at:  http://www.scummvm.org/

decompress source code with:
tar xfvj scummvm-0.4.1.tar.bz2
cd scummvm-0.4.1
patch -p1  < scummvm-0.4.1-zaurus.patch

then edit Makefile, to change the path of your gcc cross-compiler,  if it is needed..
I use /opt/Embedix/tools as path, like in standard zgcc-2.95  distribution available at myzaurus.com

scummvm-0.4.1-zaurus.patch
