GTA: SA Vita

GTA: SA Vita

This is a wrapper/port of Grand Theft Auto: San Andreas Android for the PS Vita with lots of custom patches such as:

• Fixed camera controls for flying vehicles (including the Hydra jet).
• Fixed broken facial expressions.
• Fixed cheats hash key table.
• Removed specular lighting on pedestrians.
• Added PS2-like rendering.

The port works by loading the official Android ARMv7 executable in memory, resolving its imports with native functions and patching it in order to properly run.

Setup Instructions (For End Users)

(If you have already installed the game and want to update to a newer release, you can simply install GTASA.vpk on your PS Vita).

In order to properly install the game, you'll have to follow these steps precisely:

• Install kubridge and FdFix by copying kubridge.skprx and fd_fix.skprx to your taiHEN plugins folder (usually ux0:tai) and adding two entries to your config.txt under *KERNEL:

  *KERNEL
  ux0:tai/kubridge.skprx
  ux0:tai/fd_fix.skprx

Note Don't install fd_fix.skprx if you're using repatch plugin

• Optional: Install PSVshell to overclock your device to 500Mhz.
• Install libshacccg.suprx, if you don't have it already, by following this guide.
• Obtain your copy of Grand Theft Auto: San Andreas v2.00 legally (com.rockstargames.gtasager is not supported!) for Android in form of an .apk file and one or more .obb files (usually main.8.com.rockstargames.gtasa.obb and patch.8.com.rockstargames.gtasa.obb located inside the /sdcard/android/obb/com.rockstargames.gtasa/) folder. You can get all the required files directly from your phone or by using an apk extractor you can find in the play store. The apk can be extracted with whatever Zip extractor you prefer (eg: WinZip, WinRar, etc...) since apk is basically a zip file. You can rename .apk to .zip to open them with your default zip extractor.
• Open the apk with your zip explorer, extract the assets folder from your .apk file to ux0:data and rename it to gtasa. The result would be ux0:data/gtasa/
• Still in the apk, extract the file libGTASA.so from the lib/armeabi-v7a folder to ux0:data/gtasa.
• Open the main.8.com.rockstargames.gtasa.obb with your zip explorer (.obb files are zip files just like .apk files so just rename the .obb to .zip) and extract the contents to ux0:data/gtasa.
• Same as before, open the patch.8.com.rockstargames.gtasa.obb with the zip explorer and extract the contents inside the zip to ux0:data/gtasa.
• Download the gamefiles.zip and extract the contents to ux0:data/gtasa (if it ask about overwriting files, say yes).
• Optional: For a more authentic console experience, copy the file ux0:data/gtasa/data/360Default1280x720.cfg to ux0:data/gtasa/ and rename it from 360Default1280x720.cfg to Adjustable.cfg. This file is a leftover from the Xbox 360 version and provides you the console HUD (e.g. radar on bottom left).
• Install GTASA.vpk on your PS Vita.

If you have followed the steps correctly, this is how your ux0:data/gtasa folder should look like.

Configurator App

After fully installing the port, you'll be able to configure it with the Configurator app.
The Configurator app will allow users to enable or disable a set of optimizations, patches and renderer alterations to best match users taste.
You can launch the Configurator app by clicking on the Configuration button located on the LiveArea section of the port as shown in the following screenshot.

Tips and Tricks

• In order to reduce occasional stutters in-game, delete both ux0:data/gtasa/scache_small_low.txt and ux0:data/gtasa/scache_small.txt, then create a copy of the ux0:data/gtasa/scache.txt file to have two version of it. (for example scache(1).txt so in the end you end up with both scache.txt and scache(1).txt inside the ux0:data/gtasa/ folder), then rename scache.txt to scache_small.txt and scache(1).txt to scache_small_low.txt . This will however make the loading screen longer since it needs to compile more shaders ahead.
• You can input PC cheats by pressing L+SELECT to open the on-screen keyboard. See CHEATS.md for available and unavailable cheats (you can input cheat codes in lowercase as well as uppercase).
• The L2/R2 buttons are mapped to the rear touchpad on the top and the L3/R3 buttons are mapped to the front touchpad on the bottom. With v1.2 and higher, you can map L2/R2 to the front touchpad on the top.
• You can open the map by holding START and then releasing.
• In order to save storage on your Memory Card, you can safely delete all files in sub-folders of ux0:data/gtasa/texdb which end with:
  • .dxt.dat, .dxt.tmb, dxt.toc
  • .etc.dat, .etc.tmb, etc.toc
• To get local freeroam coop and rampages working you will need to replace the main scripts with those of the PS3 version:
  • Keep in mind that saves made with the old files will be incompatible with a game using the new files and vice-versa.
  • Obtain mainPS3.scm and scriptps3.img from the /PS3_GAME/USRDIR/PS3Data.obb -> /data/script folder of a PS3 copy. In order to extract the .obb file rename it to .zip and use your favorite archive extractor.
  • Rename the files to mainV1.scm and scriptv1.img and copy them to both ux0:data/gtasa/data/ and ux0:data/gtasa/data/script/ replacing both original files in both directories each time.
  • To use the multiplayer functionality navigate to a corresponding marker (a list can be found here Marker locations ). You will have to have another controller connected via Bluetooth and set up as controller number 2 (you can configure that via the qick menu, accessible by holding the PS-Button on that controller once connected).
  • On a PSVita (as opposed to on a PSTV) you will also need to use MiniVitaTV to connect the controller in the first place.

Build Instructions (For Developers)

In order to build the loader, you'll need a vitasdk build fully compiled with softfp usage.
You can find a precompiled version here: Linux / Windows.
Additionally, you'll need these libraries to be compiled as well with -mfloat-abi=softfp added to their CFLAGS:

• openal-soft

  • Remove -ftree-vectorize from Makefile.vita.

  • make -f Makefile.vita install

• libmathneon

  • make install

• vitaShaRK

  • make install

• imgui-vita

  • make install

• kubridge

  • mkdir build && cd build
    cmake .. && make install

• vitaGL

  • make HAVE_SBRK=1 SOFTFP_ABI=1 SHARED_RENDERTARGETS=1 NO_DEBUG=1 install

Finally, in the folder of gtasa_vita, install SceLibc stubs using:

make -C libc_bridge install

After all these requirements are met, you can compile the loader with the following commands:

mkdir build && cd build
cmake .. && make
