There were actually 20 more game jams before that one which had a different naming pattern, I reset the count for various reason, but just like with the previous example, simly change the numbering part of the url and it should bring you to where you need:

https://itch.io/jam/18th-rpg-maker-horror-game-jam

https://itch.io/jam/17th-rpg-maker-horror-game-jam
