Steffen made 'Game Save Resigner' in 2015 and was effective very long time. Unfortunately the most recent version of DOA5LR 1.10Cp1 changed something so not compatible anymore. Steffen and I confirmed work with 1.10Cp1. I asked him for the source files then he was kindly enough to put these on github. You can get the source codes of the tool(with other analyzing tools). https://github.com/SteffenL/doa5lr-gamesave-tools At this very moment the tool is not work with 1.10Cp1. However, his source codes will be huge clues for the solution for the current version. It works with the most recent version. Thanks again Steffen!!!
