Hi,
there were 3 erroneous bytes in roma16-l.bin - illegal book moves.
These moves are detected to be illegal by the program and not performed.
Instead the program calculates the move to be done.
That's why no one has noticed the bad romdump.

Here are the errors:

1.e2-e4 e7-e5 2.f2-f4 e5xf4 3.Nb1-c3? Qd8-h4+ 4.Ke1-e2 d7-d5

Correct:
5.Nc3xd5 Bc8-g4+ 6.Ng1-f3 Bf8-d6 7.d2-d4 Nb8-c6 8.e4-e5 0-0-0
