Character-selection and achievement art are from the extracted Repentance files. Starting health, pickups, and items reflect the base player records with reviewed special-character conversions. Combat stats use reviewed Repentance 1.7.9b references because those values are hardcoded and absent from the player XML. Unlock conditions and the additional rewards use reviewed Repentance achievement records and completion references. Repentance+ may differ.
