funnily enough, I tried it repeatedly and had some trouble after I activated console commands via unren. Turns out you'd be better by activating it via the file itself.
TLDR. Unren doesn't work. Do it manually with this
Now to enable Console Commands:
Go to "Renpy game xxx"/ Renpy / Common / 00console.rpy
ctrl+f and enter config.console
Set config.console variable to True
Example..... config.console = True
Save file
in game press shift O (letter)
@Cirelc I had no idea about this, I just used google "renpy console" and ended up on a deleted thread without noticing
