Issues with Bitcoin Core 0.9.3 block chain. Does it work anymore?

Im expecting problems with block chain from Bitcoin Core v 0.9.3.
First issue in assert in line 156, its not passing.

assert self.get_uint32() == 0xD9B4BEF9  # magic network id

Another issue (if I comment previous assert) is not expected opcode:

BLOCK 43054 b'14508459b221041eab257d2baaa7459775ba748246c8403609eb708f0e57e74b'

Thanks.

How can dump all hash160, and address with unspent balances?

P.S.
Similar error in scanning blk00004.dat Block 128 Transaction 124

KeyError: blk00001.dat and ... block files.

When I run script balances.py with blk00000.dat everything ok, but blk00001.dat and next is was stopped with error:

user-comp:blockchain user$ python3 balances.py blk00001.dat
Traceback (most recent call last):
