New Revision: 56993

Added:
   pypy/dist/pypy/lang/gameboy/profiling/
   pypy/dist/pypy/lang/gameboy/profiling/__init__.py
   pypy/dist/pypy/lang/gameboy/profiling/gameboy_profiling_implementation.py
   pypy/dist/pypy/lang/gameboy/profiling/profiling_cpu.py
Modified:
   pypy/dist/pypy/lang/gameboy/gameboy_implementation.py
Log:
added profiling version, which uses a logging cpu, thus allows to create histograms of the executed OP-codes
