For all Unren users,

Bad news since the release of Ren'Py 8.4.*, no tool is capable of decompiling rpyc files anymore.
This is because Ren'Py decided to change the file structure and implement anti-reverse engineering measures to prevent this.

We must therefore wait for an update of the unrpyc tools from CensoredUserName or rpydec, or even a new tool.

Are we able to "rebuild" the game in a lower ren'py version sdk - and do it that way?

Did you check the dev branch of unrpyc? It did get an update 3 weeks ago to support the latest changes from renpy 8.4...

Maybe Madeddy might know better?

I'm talking about this:

The person in the issue you linked still uses unrpyc v2.0.2 and not the one from the dev branch...
If you look at the commits from the dev branch you can see the work for supporting 8.4 was started in January and 3 weeks ago some additional work was done to support newly added attributes:

Be aware it's the dev branch and there might still be some issues. Looking through the pull requests there seems to be a problem with else statements:

This should probably be fixable by changing line 407 in decompiler/__init__.py from
Code: 
if (i + 1) == len(ast.entries) and not isinstance(condition, renpy.ast.PyExpr):
to

Code: 
if (i + 1) == len(ast.entries) and not isinstance(condition, (renpy.ast.PyExpr, renpy.astsupport.PyExpr)):
if I understand it correctly, but that would need some tests (so if someone reports else statement errors this might be a way to fix it...)

That's why I said it was a temporary solution. I'll update when it's published in the master branch.

Yeah. I expected already last year, after i catched by chance some dev talk, Ren'Py v8.4 will break again some stuff. In January there was then prove. (See image)

There is likely even more as the code errors as we got so far, because not every game uses the all functions which have "new" code. In the past there where games with new Ren'Py, but decompiled with "some" old unrpyc versions. o_O

Exactly. That's one of the reasons why the dev branch sits for a while before release. As you perhaps noticed current dev has still some fixes missing for now. It will come with time...

Good morning, good afternoon, or good evening. I don't know if it works that way for him, but when I try to use this new version in Renpy 7.4 to 8.0 games, it shows the rpyc files but closes the program. In the forall version (v9.4) (240216), they extract normally without closing, but it doesn't work in Renpy 8.4

The temporary fix for 8.4 have a side effect for older Ren'Py.
So, use the previous version for Ren'Py 7 and the new with Ren'Py 8.4.*.
