Preenv Tutorial: How to install game in eMMC FAT32 partition! Saving Opt partition freespace

Hey guys I have finally achieved my little test with installing Games to the N900 into eMMC 27GB partition instead of 2GB Opt partition. After a lot of Trail and errors I've succeeded :) Got my Sim3 folder intalled on my FAT32 partition instead of Opt. Saving a hug chunk of space in Opt.

The process may takes quite a bit of work but it worth the time and efforts. I've simplified the process to make it Newbie compatible :D

Here is the step:

1. First extract your xxx.ipk file with either zip utilities such 7zips or any others.

2. Connect the N900 to your Computer via SSH (You can do via commandline also but required more works). Screenshots

3. Create a folder called Games (Anything you would like in this example I'll use "Games") in /home/user/ directory. And right click on the Games folder then set the permision to user 29999. (Look at the screenshots)

4. Now browse to your MyDocs partition "/home/user/MyDocs/" and create another folder called Games or anything you'd like.
- right click on Games and apply the permission like the picture below.

- Create a folder called Sim3 (for game called Sim3, for other games use the appropriate name for it. You'll need it later), and inside the Sim3 folder create another folder in the following path like: /home/user/MyDocs/Games/Sim3/usr/palm/com.ea.app.sims

Copy the extracted files from .ipk file and copy it to your

5. inside /home/user/MyDocs/Games/Sim3/usr/palm/applications/com.ea.app.sims/
folder, you should now see a file called "sims" right click and properties and check the permission setting. Should look like below:

Click OK to confirm.

6. Go back to /home/user/Games, and copy the file called: sims from your "ipk" extracted folder to here.
Right click and set the permission like below:

7. Now this is the SymLink part. On your N900, open Xterminal and login as ROOT.

root
for file in /home/user/MyDocs/Games/Sim3/usr/palm/applications/com.ea.app.sims/res_sims3/; do ln -s "$file" /home/user/Games/Sim3/; done

Finally:

Now create these files for Sim3 game:
You can create the icon file by using desktopgen command, make sure you put the Appinfo.json into /home/user/Games/Sim3 then:

root
preenv
desktopgen /home/user/Games/Sim3/appinfo.json

For Asphalt5 and Monopoly and few other games you will have to create a folder inside /home/user/Game/Asphalt5/Asphalt5

This can be done via SSH or commandline.
Xterminal: mkdir /home/user/Games/Asphalt5/Aphalt5
SSH: Create new directory
Copy the file called: Asphalt5 to the folder you just created and then symlinks other files from the FAT32 there.

for file in /home/user/MyDocs/Games/Asphalt5/usr/palm/applications/com.gameloft.app.asphalt5/Asphalt5/*; do ln -s "$file" /home/user/Games/Asphalt5/Asphalt5/; done

Following this step for Monopoly as well and other games :)

Done!
Enjoy! :)
I may have missed a few steps along the way but this should be good enough for now. This tutorial is based on Sim3 game :) it works for NFS Undercover and others as well.

Sorry I forgot to remove some old steps i took but now it should be fine :) I have removed the old step 6 and now should make the tutorial much easier.

Good luck :D
