I have added the Windows and Mac versions of ZC to the project entry here:

https://www.allegro.cc/cc/depot-project-files/ZeldaClassic1

The Linux version is 43MB in size, and I have encountered issues with the FTP option.

I tried all of the following:

TLS Explicit (Auth/TLS) both PASV and not PASV --this seems correct, as the form states to use Explicit.

SFTP (SSH)
SSL Implicit

While I can get a dir listing, after the first 4KB of data transfer, I receive an error aborting, because of lack of correct permissions to write.

I'm not sure what is going on there, but perhaps updating the site transfer, or permitting a direct upload, would be better options. I'm not sure why a direct binary file upload is not one of the options, TBH.

The file in question, is here:
http://timelord.insomnia247.nl/zc/zc-2-50-2-linux.tar.gz
'Zelda Classic and ZQuest 2.50.2 (Stable) for Linux'

Is the 100MB limit detailed for FTP uploads a typo? If so, someone may want to fix that.

For whatever reason, the Linux build is always 4x the size of the OSX and Windows builds.
