Preenv is a set of libraries and stubs that should make running WebOS native applications possible on the [[Nokia N900|N900]].

Note that "native applications" are a small subset of all WebOS applications; most of these are OpenGL games.

83.84.225.141: Added Shrek Karting

==How to install Preenv?==

Gain [[root access]] and use <code>apt-get</code> in the [[terminal]]:
$ root
# apt-get install preenv
# exit

== What do I use to extract an ipk file? ==

[http://7-zip.org 7-zip] or any other tool able to extract Debian packages (dpkg, file-roller, ...)

Here is the Video guide on how to install WebOS games to the N900 http://www.youtube.com/watch?v=pGQwWZ_VriA

Or you can follow the steps below...

==How to install a game==

use 7-zip to extract -> game-folder

Copy the game folder to <code>/home/user/[webOS-games]</code>:

$ sudo gainroot
$ cd game-folder
$ chmod a+x filename

e.g. <code>filename</code> = <code>nfsuc</code> in need for speed case or sims in case of sims3

$ preenv
$ ./filename

Once you know that the file plays properly. you can add the menu button:

$ sudo gainroot
# preenv
# desktopgen game-folder/appinfo.json
# exit

==How to delete a game==

Enter preenv and cd into the game folder:
$ preenv
$ cd game-folder

Become root and use desktopgen to delete game icons:
$ root
# preenv
# desktopgen -r appinfo.json
# exit
# exit

Now you can delete the game folder itself:
$ cd ..
$ rm -r game-folder

=== Deleting games installed with old preenv 0.1 ===

Become root and delete the folder:
$ sudo gainroot
$ rm -r game-folder

To remove the icon, you need to delete three files:
$ rm /usr/share/applications/hildon/filename.desktop
$ rm /usr/share/dbus-1/services/filename.service
$ rm /usr/share/icons/hicolor/scalable/hildon/filename.png

Refresh your menu:
$ killall hildon-desktop

==How to get N.O.V.A working?==

Install extra packages for N.O.V.A, then follow the regular install guide.

$ sudo gainroot
$ apt-get update
$ apt-get install libsdl-net1.2

==How to get Monopoly Classic working with an icon?==

After installation and creating an icon, lastly follow it with this step

$ cd *monopoly
$ root
# chmod -R 777 monopolyclassic/save

==How to get Asphalt5 working?==

Here is another video guide http://www.youtube.com/watch?v=8rDCbZ3gyYE

How to make it run:

$ mkdir -p /home/user/webos/gamesave
$ ln -s /home/user/webos/gamesave /media/internal
$ chown -R user:root /home/user/webos/
$ chmod -R 755 /home/user/webos/
$ chown -R user:root /home/user/webos/gamesave
$ chmod -R 755 /home/user/webos/gamesave

== How to get NFSU Working? ==
'''Easy way:'''

install [http://maemo.org/packages/view/nfsu-installer/ nfsu-installer] from extras-devel via Application Manager and run it. See [http://www.youtube.com/watch?v=-f-a-7yakkM youtube video] on how it works.

'''Manual way:'''

get root
root
install preenv and OpenGLES1 (need extras-devel)
apt-get install libgles1 preenv
create main game dir on eMMC card
mkdir -p /home/user/MyDocs/Games/nfs
go to that dir and copy dowloaded .ipk file from desktop (or download directly here)
cd /home/user/MyDocs/Games/nfs
scp user@COMPUTER:/path/to/game/com.ea.app.nfsuc_20.0.28_all.ipk /home/user/MyDocs/Games/nfs
create file for loopback mount
dd if=/dev/zero of=/home/user/MyDocs/Games/nfs/nfsu.ext2 count=120 bs=1024k
create ext2 filesystem on it
mkfs.ext2 /home/user/MyDocs/Games/nfs/nfsu.ext2
press 'y'<br>
make mountpoint
mkdir /mnt/nfsu
save it to the fstab
echo -e "/home/user/MyDocs/Games/nfs/nfsu.ext2\t/mnt/nfsu\text2\tloop,auto\t0\t0" >> /etc/fstab
finally, mount it
mount /mnt/nfsu/
create symlynk from /usr/palm (NFSU installs there)
ln -s /mnt/nfsu/ /usr/palm
extrack .ipk file
dpkg -X /home/user/MyDocs/Games/nfs/com.ea.app.nfsuc_20.0.28_all.ipk /mnt/nfsu/
make binary executable
chmod +x /mnt/nfsu/applications/com.ea.app.nfsuc/nfsuc
create desktop launcher
desktopgen /mnt/nfsu/applications/com.ea.app.nfsuc/appinfo.json

== Unable to connect to USB after above method? ==

If after following the following tutorial, you are unable to connect your N900 to your PC's USB, open xterm on your device:

get root
root
unmount the image file
umount /mnt/nfsu

Once you're done with USB you can remount the image
mount /mnt/nfsu

==How to get Driver working==
'''Install libgles'''
* get root
root
* install OpenGLES1 and OpenGLES2 (need extras-devel)
apt-get install libgles1 libgles2

'''Fix corrupted/black graphics problem'''
* Create file /etc/powervr.d/driver.ini containing these 2 lines:

[default]
ForceExternalZBuffer=0

see [http://talk.maemo.org/showpost.php?p=862561&postcount=455]

==How to get Shrek Karting working==
'''Install libgles1'''
* get root
root
* install OpenGLES1 and OpenGLES2 (need extras-devel)
apt-get install libgles1 libgles2

'''Improve corrupted/black graphics problem'''
* Create file /etc/powervr.d/ShrekKarting.ini containing these 2 lines:

[default]
ForceExternalZBuffer=0

Graphics are stil not perfect - lighting textures are still not good.

== Save space (Transfer games to MyDocs folder) ==

If running out of space in the /home/user/[webos] directory, part of the game that usually takes up the most space can be copied to /home/user/MyDocs. ''NOTE'': You still need the game folders to be in the /home/user/[webos] directory, only some of the files are transferred to MyDocs.

'''Example using NFSU'''

The example assumes NFSU does not exist in /home/user/[webos].

Open xterm, create a folder in MyDocs:
mkdir /home/user/MyDocs/preenv
mkdir /home/user/MyDocs/preenv/nfsu

Create NFSU folder in /home/user/[webos]:
mkdir /home/user/[webos]/com.ea.app.nfsuc

Copy ''only'' the files indicated as below from the NFSU source (location where ipk file has been extracted) to /home/user/[webos]
cp [SOURCE]/com.ea.app.nfsuc/appinfo.json /home/user/[webos]/com.ea.app.nfsuc/
cp [SOURCE]/com.ea.app.nfsuc/nfsuc /home/user/[webos]/com.ea.app.nfsuc/

Copy res_nfusc folder from NFSU to MyDocs:
cp -r [SOURCE]/com.ea.app.nfsuc/res_nfsuc /home/user/MyDocs/preenv/nfsu/

Now create a symbolic link res_nfsuc in the [webos] nfsuc folder that points to the actual res_nfsuc folder in the MyDocs folder:
ln -s /home/user/MyDocs/preenv/nfsu/res_nfsuc /home/user/[webos]/com.ea.app.nfsuc/res_nfsuc

Don't forget to change the permission of the executable nfsu file in [webos]:
sudo gainroot
chmod +rwx /home/user/[webos]/com.ea.app.nfsuc/res_nfsuc/nfsuc
exit

Now you should still be able to play NFSU, having saved roughly 110MB on /home/user/[webos].

'''Example using BrainChallenge'''

The example assumes BrainChallenge does not exist in /home/user/[webos].

Open xterm, create a folder in MyDocs:
mkdir /home/user/MyDocs/preenv
mkdir /home/user/MyDocs/preenv/brainchallenge

Create BrainChallenge folder in /home/user/[webos]:
mkdir /home/user/[webos]/com.gameloft.app.brainchallenge

Copy ''only'' the files indicated as below from the BrainChallenge source (location where ipk file has been extracted) to /home/user/[webos]
cp [SOURCE]/com.gameloft.app.brainchallenge/appinfo.json /home/user/[webos]/com.gameloft.app.brainchallenge/
cp [SOURCE]/com.gameloft.app.brainchallenge/icon.png /home/user/[webos]/com.gameloft.app.brainchallenge/

Copy files from the brainchallenge folder from BrainChallenge source to MyDocs:
cp [SOURCE]/com.gameloft.app.brainchallenge/brainchallenge/*.* /home/user/MyDocs/preenv/brainchallenge/

Also copy any subdirectories in the brainchallenge folder to MyDocs:
cp -r [SOURCE]/com.gameloft.app.brainchallenge/brainchallenge/sounds /home/user/MyDocs/preenv/brainchallenge/

Copy the following code and save it to a file with the name 'createln.sh'. ''NOTE'': Do not save this file using Windows Notepad; if using Windows, use software like TextPad to save the file in unix format. Copy this file to any folder on your N900.

#!/bin/sh

cd $1
files="`ls -1 $1`"

for file in $files
do
echo $file
ln -s $1/$file $2/$file
done

Create folder brainchallenge in [webos] brainchallenge folder:
mkdir /home/user/[webos]/com.gameloft.app.brainchallenge/brainchallenge

Copy the brainchallenge executable file from Brainchallenge source location to the [webos] folder:
cp [source]/com.gameloft.app.brainchallenge/brainchallenge/brainchallenge /home/user/[webos]/com.gameloft.app.brainchallenge/brainchallenge/

Now create symbolic links in the [webos] nfsuc folder that point to the actual files in the brainchallenge folder located in MyDocs (using ''createln''):
sh [..]/createln /home/user/MyDocs/preenv/brainchallenge/brainchallenge/ /home/user/[webos]/com.gameloft.app.brainchallenge/brainchallenge

Also create symbolic links to any folders inside the brainchallenge folder in MyDocs:
ln -s /home/user/MyDocs/preenv/brainchallenge/brainchallenge/sounds /home/user/[webos]/com.gameloft.app.brainchallenge/brainchallenge/sounds

Don't forget to change the permission of the executable brainchallege file in [webos]:
sudo gainroot
chmod +rwx /home/user/[webos]/com.gameloft.app.brainchallenge/brainchallenge/brainchallenge
exit

Now you should still be able to play BrainChallenge, having saved roughly 114MB on /home/user/[webos].

The method used for the BrainChallenge game has also been tested and works with Asphalt 5, Blades of Fury, Oregon Trail and X-Plane Airliner.
