Note that you will need to use applocale to run danmakufu (or vpatch.exe) if your system isn't running in Japanese locale.  Check here for an explanation on applocale if you aren't familiar with it: https://www.shrinemaiden.org/forum/index.php/topic,25.0.html

Some general information on the gameplay: http://en.touhouwiki.net/wiki/Magical_Singular_Day/Gameplay

Note that pressing C will activate a hyper, or cancel suicide bullets during a hyper.  Holding C and pressing X during a hyper will allow you to end a hyper early.  Good hyper usage is important for both score and survival, especially on higher difficulties
