Hellcat released a new version of Savegame Deemer, which is now compatible with 6.20 TN. What exactly does deeming your PSP saves do?
Add a new line to seplugins/game.txt activating the plugin, and now whenever you save a game that data is saved unencrypted. You can now exercise your hex editing skills and hack those saves: give yourself some extra cash, XP, advance a quick level or two, whatever… Savegame Deemer will later load those unencrypted & hacked saves giving you the leading edge. Refer to readme.txt for everything else you should know
