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

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

The original game files are required in order to run this.

Installation

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):

• 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.

v0.2.07

• Chambers 19 and Escape 02 added (with GlaDOS boss fight, and a cinematic ending), have added the ending credits for the game also!
• Significant amount of re-modelling, LODs, and refinements with a focus on maintaining FPS and user experience
• Fixed a significant number of major bugs/issues discovered by users in the different levels pertaining to puzzle elements not appearing in correct place, missing models, not being lit, and I probably introduced a few more bugs somewhere so that could be a fun game to discover them all
• Fixed significant bug that allowed the player to frequently punch through the level geo
• Re-lit many of the levels as lighting had a very patchy feel
• Implemented clock control to give a better framerate for users, and also tried to implement Unity's culling system as best I could
• Fixed the slide-hop bug that was befouling players exiting portals
• Chamber 19's crusher won't kill the player so have fun with that!

v0.1.86

• Chambers up to Chamber 18 are now in the game and mostly playable save a few little hiccoughs.
• We have turret drones, and they say stuff.
• Created a stack of LODs for props which has helped to punch up performance in many areas.
• Totally overhauled high energy pellet behavior so that it was predictable and didn't suffer random actions that Unity's physics engine tends to give objects. This also fixes issues where the pellet won't go through portals, or will simply go through walls.
• Added a quick respawn volume what will let the player restart close to a puzzle they were attempting to solve without having to reload the entire level again
• Correctly sized Companion cube and other props.
• Player can now crouch! Crouch is handy for a lot of different things. It's mapped to Square.
• Mopped up some sundry bugs and issues, further refined player movement with a focus on making flings more "natural", added context-specific auto-aim to help for situations where the player had to do trickshots, tweaked jump mechanics so that the player makes a little leap when they first jump - and lots of other good stuff!

v0.1.27

• First Release.

Credits

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 as well as Valve for their life-changing game!
