DOA6 fighter cards extracted as PNG from the game itself using RenderDoc, and more.
Some have subtle differences compared to the ones released online.
DOA6_character_cards.zip - 58 MB - 32 files...
By analysing the DOA6.exe file with a resource extractor a bit (used Resource Hacker) I found the login splash screen picture.
That picture still had some old metadata buried within (used ExifToolGUI).
What I find interesting is the "Create Date" section: 2017-12-08. That's one week before that...
