Very niche feature but it was awesome. Yatse worked perfect with Advanced launcher when it was still active. Showed artwork and launched games. Now Advanced emulator launcher is it’s successor and it’s never worked with yatse(no artwork and error on launch). Just putting this out there in case anyone cares.
This is something for the addon to fix not Yatse.
There’s no API and nothing more that what Yatse currently do.
