Could the fades be optional? Thanks

No. that's stupid

what I mean is: it's a lot of unnecessary work to add in more options just for a minor detail like this

Added an optional sound-effect to the popup.
It tries to play the file "/sounds/trophy.wav"

I deleted my trophy save in LittleBigPlanet 2 and booted the game. Trophies appear again when savegame loads, but no pop-up sound. Not in the first one, or the last one.

Did you put a .wav file into "/sounds/trophy.wav" as mentioned ?
if the folder doesn't exist in your rpcs3 directory then you have to create a new folder manually.

I thought your code would already do the extracting part of the .rco, added the sound now and it works, but this happens:

My case is extreme, of course. But unlocking two or three trophies at the same time is not exactly difficult, it will certainly happen whenever someone gets a platinum trophy.

lol. thx
I actually wanted to test it but I forgot. (I have a small piece of code that let's me spam those trophies)

I fixed it. Should be in the next update
