[TH14] How I can slow Touhou Kishinjou?

[TS666]

Hello, I was searching on the internet for an answer to this but there's nothing.
Is there any chance of slow DDC?, Cheat Engine does nothing but increase the FPS and the game runs like it were at 60FPS.
Rather than explain, look at this...

You can clearly see that the game is running at ~120FPS, however, if I set speedhack to 2.0 the game will run at ~30FPS but without real changes in the speed (slowdowns or speed ups), just running at normal speed.
