[REQUEST] compatibility with versions from the rs archive

[iwantasandwich]

Use case

Importing older versions of runescape.
E.g: to export the now removed maps of dungeoneering mainly daemonheim

Solution

Honestly i have no clue

Additional context

Older caches are downloadable here:
https://archive.openrs2.org/caches

But they seem to be missing xteas.json
And params.txt
