Dr Fink's Robot Lab Vita

This is a wrapper/port of Dr Fink's Robot Lab for the PS Vita.

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 it is.

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:

• SDL2_vitagl

• libmathneon

  • make install

• vitaShaRK

  • make install

• kubridge

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

• vitaGL

  • make SOFTFP_ABI=1 HAVE_GLSL_SUPPORT=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
