Found these after editing the save file.
Probably some leftover code from previous games, KEK.
Done some slightly edit to the MTL, but I don't feel it's still good enough to publish it here. Requires lots of cleanup and fixing.
But I can leave the save file, without the Story Mode 2 and 3 buttons of course. Extract and put it in the "PapaGAL_Data" folder.
PS: Does anyone know what the "ガード表示" button does in the options? It translate it as a "Guard Show", and in the savefile is reported as "Haka Mode" in the savefile. Have no clue on what it does in game.
PPS: I've also noticed JSK removed the ability to set in the option the "cum number", now the MC just nuts very quickly without possible variations.
