Just recently got this game on GOG and was interested in speedrunning it. I have a few questions, though.

Is there a way to get the game into windowed mode?

Is there a community discord or skype or anything like that?

Is there a fastest language?

Thank you for your time

The fastest language is Italian.

As for windowed mode, altough I wish so much it could be done, I dont think there's any way of doing it

There are Discord and Skype groups, Discord is more activ for now. We also have SDA forum where we keep posting most important things: https://forum.speeddemosarchive.com/post/rayman_2_the_great_escape4_655.html

It should be possible to get windowed mode with nGlide 1.05 (alt+enter)

Can I get that discord invite?
