Aogami currently has more features so for now, unless there are certain features that are implemented differently compared to mine, use Aogami . I have not tried the Aogami save editor just going off his changelog.
Hey. Im currently posting the tools i created for the smtv save editor discord here just in case
SMTV save editor
Requirements: .net 6.0
SMTV Save Utility GUI (currently being updated to not rely on original tool)
Requirements: smtv.saveutil.exe by zarroboogs
EDIT: due to account...
yes. except jp voice, every dlc is on disc. we can currently set the save to be either a save that had access to dlc to one that doesnt (which blocks non dlc owners from loading dlc saves) but we still dont know how to unlock dlc content for those without the dlc files.
