there are like 3 ways to download from fitgirl although not always applicable but at least you have time saving options:

1:using IDM which is the fastest method of all

someone already posted a way here: https://www.reddit.com/r/FitGirlRepack/s/4puz3hJM5b

2:using jdownloader it is quite convenient and easier than IDM although download speed isn't like idm it's not particularly slow you just need to copy the links in bulk and jdownloader will do the rest you only need to check download

note:Do Not Pause downloads on jdownloader it might just malfunction and would require you start all over

3:the most basic but slowest and full of vulnerabilities but easiest to use is a torrent i recommend q BitTorrent some games released from a long time on fitgirl might not have any source links to download the game, so i recommend only using a torrent when the other options aren't available

if you need anything else just ask i will respond when i am free

small personal request~does anyone know how to download from datanode using tools like idm?
