Sleepwalker's Journey Vita

This is a wrapper/port of Sleepwalker's Journey for the PS Vita.

The port works by loading the official Android ARMv6 executable in memory, resolving its imports with native functions and patching it in order to properly run.

Note

This wrapper has been tested only with v.1.2.

• 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

• Obtain your copy of Sleepwalker's Journey legally for Android in form of an .apk file and a .obb file.
• Open the apk with your zip explorer and extract the file libAndroidGame.so from the lib/armeabi folder to ux0:data/sleepwalkers.
• Place the obb file named as main.obb in ux0:data/sleepwalkers.

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: 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:

• openal-soft

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

• libmathneon

  • make install

• vitaShaRK

  • make install

• kubridge

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

• vitaGL

  • make SOFTFP_ABI=1 PHYCONT_ON_DEMAND=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 .. && make
