+Turns out EID already have some support for this, using a save extractor. If you want to go down that route, here's the link to the extractor : https://github.com/wofsauge/External-Item-Descriptions/tree/master/scripts
 
 However, EID's save extractor doesn't really work on Linux, so I made a port of it in python, in order to be more easily ran. This port is available here : https://forge.chapril.org/ayte/DeadGodHelper/src/branch/main/SaveExtractor
 This port can also extract save file's info to be used for Dead God Helper.
