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!

Setup Instructions

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 VPK 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 Decrypting the VPK:

• 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 ApetureReconstructed.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 ApetureReconstructed.xdelta, xdelta-3.1.0-x86_64.exe, and ApplyPatch.bat
• Run ApplyPatch.bat and wait for the process to complete
• Install the resulting ApetureReconstructed.vpk through VitaShell as you would usually install a game for the Vita
• The files installed by the process can now be deleted if you wish

Step 2 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
