Looks like there's a minor bug when running this through linux on proton - one of the songs appears to be Funiculì, Funiculà, which, when downloaded, results in broken ASCII boxes. This results in an incorrect filename which causes loading errors during the pizza scene.
Fixing it locally is as easy as changing the relevant filename to Funiculì_Funiculà.ogg, but it might just be best for you to remove the accented letters from the filename and code? That should avoid any weird errors like this
Just a heads up, this sounds like an encoding issue, and even if you change this filename it’s likely to cause future issues.
What’s almost 100% going on here is that the filenames are getting mangled on decompression, as unicode support/implementation in ZIP is kind of a shitshow.
Basically, by default ZIP assumes the encoding of the system you’re extracting to is the same as the encoding on the system that made the archive so when you open it on Linux (an OS that’s bothered to properly implement unicode) stuff gets screwy.
Rather than renaming the file I strongly suggest using software that encodes in UTF-8 by default (PeaZip does this.
7-Zip doesn’t seem to and requires a special option set that would probably be too annoying to figure out if you aren’t the kind of nerd I am.
This shouldn’t cause any issues for computers that are newer than Y2K lol.
This should fix the issue this person is having but do a test with the default windows extractor.
Create your archive with PeaZip, extract it with windows, and make sure the filename is correct. If everything looks good you should then always use PeaZip (or other software known to probably encode in UTF-8) to create your archives and never have this issue again.
I see SO MANY troubleshooting threads caused by this EXACT problem and unfortunately the only solution is using better software.
