Wishmaker does not share the same algorithm. The following use the same algorithm:
Space C, JAA, Bryant Park, 10ANNIV, Misturin Celebi, GCEA, and EU Aura Mew.
@Sabresite Thanks, I had not noticed that detail, my priority was to recreate an event pokemon based on an existing one with slight changes (no cloning).
I will do more and my next projects are:
Space C Deoxys, Jirachi Wish Maker (No Shiny) and legendary Johto's trio.
In fact I will make a mega pack of the 21 of Journey Across plus some extras.
You generated 10ANNIV and converted to 10 ANIV Celebi? It is smart to do this.
The only thing missing is the friendship should be 100. I fixed it for you using PKHex batch editor.
I will update your post with the proper one.
