Do someone has the nn1987 Arcade Press Effect(sliee note). Plz link me to it T-T
And do you have the button icon mod?.
P/S: Don't tell me use Real PDA-FT Skin X because my pc keep crash when I use it

Try this mod for your icon

(This isn't mine)

I also occurs that when using real PDA-FT Skin X and other. But when I use this mod it work fine. So this mod can allow you to change from ∆[]XO To ↑←↓→ BUT sadly it can't change to XYBA and you can't change each note one by one (like ↑←XO) .

Note: when using this mod I recommended you to restart PPD when you use it for the first time. Cause it make lag when using it for the first time (Me)

Also try this mod for your slide effect

(Again it isn't mine)

It work fine for me.
