Ok, I'll give it look later.Hi all,
@ptitSeb : looks like "To The Moon" has been updated on GOG. The Linux installer file's name is no longer gog_to_the_moon_126.96.36.199.sh. I renamed the file to gog_to_the_moon_188.8.131.52.sh for your data extractor to work, and data extraction completed successfully. The main menu seemed normal enough, but in game it didn't make any sense. The two doctors appeared to be floating above some weird background, and text was not displayed at all...
Could you please have a look ?
Cheers, Magic Sam
