I wasn't attempting to answer anything. You mentioned something about a 'Step 4' with out explaining which 'Step 4' you were thinking of.
In any case I plan on altering the receipt.(json) File*, and alter it to match up with (UnnamedGame v16), that may be c***blocked due to the stupid Payment Provider Drama of '25. Apparently that would work but it would be like hammering out a copy of it.
Thankfully this is the Third Chapter of said Game, so I have versions 7, and 14** to compare my work.
*IIRC That comes along with a given Game in Game Dir/.itch
** Again IIRC
