7days boots into game !!!

• GA330 libretro core
  • uses Unicorn to emulate CPU
• minimal replacement OS for ARM (handles loading of binaries etc.)
• some shared/portable functions (libCCOS)

First, you will need:

• C++ compiler for your host platform
• C compiler for embedded ARM (arm-none-eabi-gcc)
• working RetroArch or another libretro host

Then, to build everything:

• compile GA330 core via CMake. this step also generates thunks for miniSYS (bleh)
• compile minisys (make -C minisys)
• run/debug GA330 core via your libretro host

Currently unsolved. Unicorn is based on QEMU, but QEMU GDB stuff is probably not usable there. printf is your friend!
