The opcodes in Opcode.java are still at the stage of Python 2.5.2. This currently breaks PyBytecode.interpret and thus the whole pycimport mechanism. As a quick improvement I would fix the opcodes such that Python 2.7 compatibility is restored.
However just fixing the opcodes is probably not enough, because new semantics must be considered in PyBytecode.interpret. Fixing Opcodes.java would still be an improvement, because currently even trivial things like attribute-lookup fail.

Fixed as of commit 7986c893c14bd4fcc59da5af6e1aaa28204e1188.
Review is recommended, also more testing.
Now PyBytecode supports bytecode according to magic number 62211 (CPython 2.7).
Also: pycimport.py now checks for right bytecode-version and refuses to load unsupported bytecode; previously this potentially yielded undefined behavior (however usually ending up with NullpointerException or ArrayIndexOutOfBoundException or so).
