i have problems with XP3 viewer method, when i drag the game.exe to the xp3viewer.exe, only the game opened, the XP3Viewer just flashed up and then disappeared. I am using Win10, and this is the game https://vndb.org/v19595
EDIT: and when i try using kirikiri2, this problem showed up, i opened command prompt in the folder by shift+rightclicking
