Do you think you can dig up some of the stuff you're talking about from some of your storage media and/or storage devices? Like the guide you remember to have read?

This may lead you to more or other clues or to some sort of source of what was used in the past.

It could also be that there's some description in this forum. It's just buried somewhere. Clever use of search keywords can do magic... (try ninjastic.space, it's friendlier to search the forum there than with the forum's own search).

Your coins don't run away, you have all the time nature grants you.
