UnRen has never searched and passed this type of files for decompilation. Are you sure you really need them?
It was to translate a game into my language and then port it to Android, but I already used another advanced method

unrpyc support decompiling .rpymc files to .rpym

@mazinogamer, perhaps tell why we shouldn't decompile rpymc on that game? was there an error? it might help VepsrP to troubleshoot and fix any error (... right, VepsrP? :LOL: )
Your script passes this type of files for decompilation? I just haven't figured out exactly how it looks for and defines files for decompilation.
[[ $1 ]] && opt=("${opt[@]}" "$1")
Probably this line of code, but it's not very clear for me how it works. :unsure:

Yeah... So, if you just pass a folder to unrpyc, then unrpyc will find all *.rpyc and *.rpymc recursively in that folder. And My bash script does this (these why, I think you said about I pass all files into single unrpyc).

You can see theres a dot, on this code: "$python" "$unrpyc" "${opt[@]}" .
this is telling unrpyc to look on this current folder. the dot is an alias of current folder.

[[ $1 ]] && opt=("${opt[@]}" "$1")
Probably this line of code, but it's not very clear for me how it works. :unsure:
On shell script, the code $1, is the first positional argument of a function or the main script it self if it invoked out of a function. ($1, $2, $3, until $9: positional arguments)
And specifically on Bash conditional [[ ]] checks, you can omit the "if" keyword and the && will run the right hand code if the [[ ]] evaluates to true

So, on my script, basically if we don't pass anything to that function then it just run "--init-offset" on unrpyc parameter (the opt variable), where I set it on local opt=(--init-offset).

And on "Menu" option number 9 (try harder), I pass the "--try-hard" argument, so it will add it to the opt variable. That is all.

Hm... It might be worth trying to do the same.(y) For some reason, this idea did not occur to me.:unsure::HideThePain:

Which version of powershell do I need? When I try to run the powershell script version it just opens for a second then closes :(.

...
zlib.error: decoding with 'zlib' codec failed (error: Error -3 while decompressing data: incorrect header check)
Again: Always cite error messages completely! We don't sit on your should and see whats going on for you.
It's strange, in fact my rpatool takes the header from the engine itself, so there should be no mistakes with this. I'll check in about 7 hours when I get home from work.
This last error isn't from the header anymore. There's also something else done who zlib doens't agree with. Seeing in your custom rpatool that you do not use all of renpys loader internals, i guess they fucked with index or the stored format of the actual file data. Your rpatool doesn't account for such.

Edit: As expected. See attachment... The lines 150 to 153 are extra... how cute...

In these two lines lies the solution. Python didn't like the space in the path (at least in my code. if so, I will try to handle this case later) and he divided it into two. Just remove the space and it should work.

Thanks for the reply.
I changed the path, and now it gives the same error as Unren 1.0.10
