and i dont know how to reach you... it saiys there's discord but i couldn't find it

Hi there,

Just to clarify—everything you mentioned (including VR support and access to the Discord server) is explained on the itch.io project page under the section `Patreon, Discord, And The Future of Jav Preservation`. The key part is that these features are only available through the Patreon version of Jav-it.

If you'd like to decrypt your purchased DMM VR videos and get Discord community access, you'll need to subscribe on Patreon first. Once you do, you’ll get access Discord where you can find our community, tutorials, guides, and troubleshooting help.

Hello - I am an old noob haha - how do I join this Patreon so I can get in the discord and figure things out?

Also I guess I should ask before subscribing - if I have like half a Terrabyte of downloaded .dcv files from R18 - can I decrypt them with this Patreon version?  I can see the original "file_id" in the metadata on them - but not sure if it's possible to decrypt now that you can't login to R18 for cookies anymore etc.

Hi there!

If you check out the `README.txt` you can find all the information you need for Patreon. As for downloaded video files, *.dcv files from R18 are not supported as that website is no longer running and their licence servers are long dead. In addition, the secrets they use to secure videos are different than DMM, so cross decryption would be impossible. The only alternatives you have is to re-purchase all your titles on DMM with the Download option, or subscribe to one of their premium channels which allow downloading videos.
