its a thing to execute commands in windows, it kinda goes like this:
here i was trying to change the renderer for another game from itch, he basicaly telling you to do the same thing, go to the folder your game is in and press on here:
from there, type in: cmd
when inside the cmd, just type in: MilfsPlaza.exe
and then check for the line hes talking about (Live 2D cubism SDK)
