1.1.5 Hit and Miss with Ren'Py7.4 Games #111

Closed OrdosAlpha closed 3 years ago

OrdosAlpha commented 3 years ago

1.1.5 is hit and miss with all games produced with the latest build of Ren'Py. The bytecode.rpyb also fails to decompile the 7.4 games where un.rpyc fails to load.

Using un.rpyc:-

I'm sorry, but an uncaught exception occurred.

While running game code: Exception: Could not load file C:\Ren'Py\Ren'Py 7.4\Depravity 0.59 Hotfix/game/un.rpyc.

Does it work if you use unrpyc.py instead of un.rpyc?

huh. Can you confirm if this is with absolutely stock ren'py? The first one doesn't give much info except if fails to load that file (might be various reasons for that, but it should load with stock ren'py.

The second one is definitely weirder. Something in the python environment got properly mangled if that triggered, and I'm not sure what exactly. Seems like some decompiler datastructures are sticking around that really shouldn't be.

Hard to say anything conclusive with only the error logs though. Can you confirm if it works with command line unrpyc?

I tested the game in the users version and with unrpyc_v1.1.5 and had NO issues at all. CLI and RenPy dependent(un.rpyc) versions. Bytecode file wasn't used because unneeded. Unpacking, decompiling and running the game went without a hitch. The claim for a bug is IMO a mistake. I have the original rpa file with the scripts available if wanted(6.4MiB) by someone.

Its also beyond me why it would be needed for anyone to decompile the .rpyc files when all the related .rpy files are along them in the RPA. So, if this was just for testing then something else went wrong.

closing due to lack of response and inability to reproduce.
