PyPy is 100% compatible with CPython, it implements very tricky
implementation details just to be 100% compatible. (But PyPy support
of the CPython C API is only partial, but the C API is not part of the
"Python language".)

In short, the JIT compiler is written in a different language called
RPython. This language can be compiled to C, but other backends are or
were available: Java, .NET, Javascript, etc. (You should check, I'm
not sure.)

The whole "PyPy project" is more than just than a fast Python
interpreter. There are also fast interpreter for Ruby, PHP, and some
other languages.
