# GTA: SA Vita

<img src="./screenshots/game.png">

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.
By doing so, it's basically as if we emulate a minimalist Android environment in which we run natively the executable as is.

## 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](https://github.com/TheOfficialFloW/gtasa_vita/releases/download/v2.1/GTASA.vpk) on your *PS Vita*).

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

- Install [kubridge](https://github.com/TheOfficialFloW/kubridge/releases/) and [FdFix](https://github.com/TheOfficialFloW/FdFix/releases/) 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](https://github.com/Electry/PSVshell/releases) to overclock your device to 500Mhz.
- Install `libshacccg.suprx`, if you don't have it already, by following [this guide](https://samilops2.gitbook.io/vita-troubleshooting-guide/shader-compiler/extract-libshacccg.suprx).
- 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](https://stackoverflow.com/questions/11012976/how-do-i-get-the-apk-of-an-installed-app-without-root-access) 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](https://github.com/TheOfficialFloW/gtasa_vita/releases/download/v2.1/gamefiles.zip) and extract the contents to `ux0:data/gtasa` (overwrite if asked).
- **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](https://github.com/TheOfficialFloW/gtasa_vita/releases/download/v2.1/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

### Gameplay

- You can input PC cheats by pressing **L** + **SELECT** to open the on-screen keyboard. See [CHEATS.md](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.
- You can get local freeroam coop and rampages working by replacing the main scripts with those of the PS3 version. See [COOP.md](COOP.md).
- Due to expired licensing, some songs were cut from the game. See [MUSIC.md](MUSIC.md) for a list of removed tracks and a guide on how to restore them.
- To properly take off during *Learning to Fly* mission, retract your landing gear by pressing **RIGHT**.

### Performance

- 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.
- If the folder `ux0:data/gtasa/cache` contains much more than 300 files, it's recommended to delete the folder and have it rebuilt.

- 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`

## Build Instructions (For Developers)

In order to build the loader, you'll need a [vitasdk](https://github.com/vitasdk) build fully compiled with softfp usage.
You can find a precompiled version here: https://github.com/vitasdk/buildscripts/actions/runs/1102643776.
Additionally, you'll need these libraries to be compiled as well with `-mfloat-abi=softfp` added to their CFLAGS:

- [mpg123](http://www.mpg123.de/download/mpg123-1.25.10.tar.bz2)

- Apply [mpg123.patch](https://github.com/vitasdk/packages/blob/master/mpg123/mpg123.patch) using `patch -Np0 -i mpg123.patch`.

- ```bash
autoreconf -fi
CFLAGS="-DPSP2 -mfloat-abi=softfp" ./configure --host=arm-vita-eabi --prefix=$VITASDK/arm-vita-eabi --disable-shared --enable-static --enable-fifo=no --enable-ipv6=no --enable-network=no --enable-int-quality=no --with-cpu=neon --with-default-audio=dummy --with-optimization=3
make install
```

- [openal-soft](https://github.com/isage/openal-soft/tree/vita-1.19.1)

- ```bash
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=${VITASDK}/share/vita.toolchain.cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_FLAGS=-mfloat-abi=softfp .. && make install
```

- [libmathneon](https://github.com/Rinnegatamante/math-neon)

- ```bash
make install
```

- [vitaShaRK](https://github.com/Rinnegatamante/vitaShaRK)

- ```bash
make install
```

- [imgui-vita](https://github.com/Rinnegatamante/imgui-vita)

- ```bash
make install
```

- [kubridge](https://github.com/TheOfficialFloW/kubridge)

- ```bash
mkdir build && cd build
cmake .. && make install
```

- [vitaGL](https://github.com/Rinnegatamante/vitaGL)

- ````bash
make SOFTFP_ABI=1 SHARED_RENDERTARGETS=1 DRAW_SPEEDHACK=1 TEXTURES_SPEEDHACK=1 SAMPLERS_SPEEDHACK=1 NO_DEBUG=1 install
````

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

```bash
make -C libc_bridge install
```

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

```bash
mkdir build && cd build
cmake .. && make
```
