Abstract
We describe the conversion of simulated and recorded data by the Belle experiment to the Belle II format with the software package b2bii. It is part of the Belle II Analysis Software Framework. This allows the validation of the analysis software and the improvement of analyses based on the recorded Belle dataset using newly developed analysis tools.

Notes
Other computing centers will store additional copies of the raw data.
In this case, photons from initial and final state radiation are physically indistinguishable, since the corresponding amplitudes interfere. Actually, there is no correct answer to the question of whether the photon is final state radiation or not. Hence, the behavior of the heuristic is not wrong, but probably unexpected by the analyst, because the initial state radiation amplitude dominates in this decay.
BASF already implemented a function for recovering the lost bits, but it was apparently not applied.
