Aperture:Reconstructed

This is an explicit reconstruction of Valve's classic game Portal for the Playstation Vita.

This has been achieved by standing on the shoulders of giants, and I owe a debt of thanks to Cody Andrews and his portal implementation for Unity (https://github.com/codand/Unity3DPortals)  as well as Valve for their life-changing game!

After a lot of really hard work the game is now complete and playable through to Chamber 14.

Setup Instructions

TheTRON has made a fantastic video going into the install process in detail if you're more of the visual type, please follow this video, give him a like and subscribe because he's put in a lot of effort!

Pay attention because this has changed slightly from last time so as to support deployment on VitaDB

Due to the nature of this project there's a two-tiered level of security to prevent this project being considered as distribution of game assets. The first is that the core files of the project itself is made as a xdelta against the original Portal game files, and the second is using "portal_pak_dir.vpk" as authentication within the game itself.

Step 1 Install the VPK:

• Download the VPK from here, or from VitaDB and install as you usually would. At this stage the game will crash during launch because you need to install the Media directory that contains copyrighted content

Step 2 Convert the xDelta to Media.zip and Install in ux0:app/APTR1007/Media

• Make sure that your version of Portal is up to date. This process uses the version that's available on Steam and there's really no excuse not to buy it as it's only $9.99!
• Download ApetureReconstructedFiles_0.1.72.zip and when it's complete place it into the data directory for the steam version of the Portal game (C:\Program Files (x86)\Steam\steamapps\common\Portal\portal)
• Select "Extract here" and extract the zip into this directory. It will add ApetureReconstructedFiles.xdelta, xdelta-3.1.0-x86_64.exe, and ApplyPatch.bat
• Run ApplyPatch.bat and wait for the process to complete. The process will give you a decrypted "Media.zip" folder which contains game content
• Extract the resulting "Media.zip" folder and install over ux0:app/APTR1007/Media on your Vita, replacing any existing files in that directory
• The files installed by the process can now be deleted if you wish

Step 3 Setup Authentication:

I have designed ApetureReconstructed to require the original game file "portal_pak_dir.vpk". I do not know if this will be specific to the English version, but it's the one from the Steam distribution

Make sure that your version of Portal is up to date

• Copy "portal_pak_dir.vpk" from C:\Program Files (x86)\Steam\steamapps\common\Portal\portal to the Data directory for Apeture:Reconstructed: ux0:data/AptrRecon
• This should now appear as ux0:data/AptrRecon/portal_pak_dir.vpk
• If you wish to make this process easier you may want to run Apeture:Reconstructed first so that it will create the data directory for you, but remain stuck at the authentication screen
