My Chuni SUN seems to be using felica.txt instead, when I go to the DEVICE folder I only see felica.txt in there. So I deleted felica.txt and created a new aime.txt file myself, however when I launched the game and it still gave me the same error. When I go to the DEVICE folder again I saw that it automatically created a new felica.txt
Do I need to manually input the 20 digit card number in aime.txt if I do create it? Or can I leave it blank like the older version can? As in Chuni New and below I dont ever remember manually inputting a 20 digit card number, it just auto generates for me.
