Grand Theft Auto: San Andreas PS Vita Port

Grand Theft Auto: San Andreas PS Vita Port

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)

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

• 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 in /sdcard/android/obb/com.rockstargames.gtasa). You can get all the required files directly from your phone and they can be extracted with whatever Zip extractor you prefer (eg: WinZip, WinRar, etc...).
• Extract the assets folder from your .apk file to ux0:data and rename it to gtasa.
• Extract the file libGTASA.so from the lib/armeabi-v7a folder inside your .apk file to ux0:data/gtasa.
• Extract the whole main.8.com.rockstargames.gtasa.obb file to ux0:data/gtasa.
• Extract the whole patch.8.com.rockstargames.gtasa.obb file to ux0:data/gtasa.
• Extract gamefiles.zip to ux0:data/gtasa.
• Optional: For a more authentic console experience, copy the file ux0:data/gtasa/data/360Default1280x720.cfg to ux0:data/gtasa/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.

The ux0:data/gtasa folder should contain all the files and directories as shown below.

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, you can replace ux0:data/scache_small.txt and ux0:data/scache_small_low.txt with ux0:data/scache.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 https://gtagmodding.com/sanandreas/cheats/ for the full list of cheats (you can input cheat codes in lowercase as well as uppercase). Note that a few cheats have been removed from the Android version.
• 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.

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 bee compiled as well with -mfloat-abi=softfp added to their CFLAGS:

• openal-soft
• libmathneon
• vitaShaRK
• imgui-vita
• kubridge

As last requirement, you'll need to compile vitaGL with make HAVE_SBRK=1 HAVE_SHARK=1 SOFTFP_ABI=1 SHARED_RENDERTARGETS=1 NO_DEBUG=1 install.
After all these requirements are met, you can compile the loader with the following commands:

mkdir build && cd build
cmake -G "Unix Makefiles" ..
make
