[Notice (September 2, 2023)] There have been reports of a problem with some models where the screen locks the first time you start Roketsuma after updating it. I have confirmed that it actually just takes a while, and if you wait a few minutes, it will start up normally and then work normally. Once you start it, it won't take long to start it the second time. If you experience a symptom where the program appears to have stopped at the initial startup screen after an update, please wait a few min
