here. It doesn't have to be applied to the EXE file, but if you are using english patched games with this, remember that they need to be renamed to thxx.exe, replace xx with the number of the game. If it is below 10, the first x is always 0 and if the game is Shoot the Bullet, Double Spoiler, or Great Fairy War, the exe files need to be named th095.exe, th125.exe, and th128.exe respectively.
Also, I don't know if Touhou 13 works with the patch, I have set the boolean in the .ini file to forget checking for authenticity.
The files for each folder are
vpatch_thxx.dll or vpatch_thxxx.dll or vpatch_alcostg.dll or vpatch_th_dnh.dll
vpatch.exe
vpatch.ini
And then just change GameFPS from "GameFPS = 60" to "GameFPS = 90"
