One Thousand Lies .rpa files

[wawon0]

https://mega.nz/#!8kFjjSbB!t5ShTSDtXSJb ... urMImcloPs
Here is the only archive file

[aluigi]

It's a Ren'Py archive ("RPA-3.0"), so this is the script to use:
http://aluigi.org/bms/rpa_renpy.bms

If you don't have python installed you can use this other script:
http://aluigi.org/bms/rpa_renpy_nopython.bms

[bugmenot]

aluigi, any chance you can take a look at https://gofile.io/?c=1Y7GeA and see why it isn't working with the scripts you quoted? A Python based script can unpack the files without a problem but I'd prefer not to have to install it.

P.S. If you'd like a look at the Python script just send me a PM.

[aluigi]

Ok I have updated the nopython script to version 0.1.2.
Please note that it's still a work-around and not a full implementation but it does the job with the archive you provided.

[bugmenot]

Thanks.

[bugmenot]

Here is another example where the script doesn't work (if you have the time to check it): link is dead

[aluigi]

Ok I decided to give up with the work-arounds and finally we have a Python Pickle deserializer that can be implemented in any script, including the RPA one
Script 0.2 + http://aluigi.org/bms/pickle.bms

[bugmenot]

Do I use it as usual or is there something specific about it?

The script works perfectly with the 2 archives you provided.
Are you using the script with other archives?

[bugmenot]

Yes, here is an example: https://gofile.io/?c=YEiXjX

P.S. The old RPA archives (ren.py) (no python version) (script 0.1.2) is working fine for that one.

[aluigi]

Ok I have updated pickle.bms to version 0.1.1:
http://aluigi.org/bms/pickle.bms

Anyway I have not found the same error you reported, here the only error was the offset/size because LONG1 and LONG4 were not correctly converted to number while in your example I see also problems with the filename.

[bugmenot]

The same error with version 0.1.1, here is the file I'm testing with: https://gofile.io/?c=YEiXjX
I'm using quickbms v0.7.7.0 by dragging the bms file over the exe and then selecting the rpa file and the output folder.

Here I have no errors. Everything works perfectly.
I have also checked the md5 of the online scripts and they are correct:
35cf4d7e8d4d31cdd24ea7cd4dcef228 *rpa_renpy_nopython.bms
48d376c5d5849c680f1bbd3779572e33 *pickle.bms

[bugmenot]

Now i see what the problem was - I had to use the two files together.

Can you check what's the problem with the attached file (might be corrupt although I don't think so - I used offzip -a file folder 0 to unpack it from the zlib compressed version)

P.S. Thanks for all the time you spent on this.

Now i see what the problem was - I had to use the two files together.

What you mean?
Both rpa_renpy_nopython.bms and pickle.bms must be in the same folder yes.

Just a note, I did a test by using quickbms in GUI mode (double click on quickbms.exe) and the only error I had was with the (re)loading of the input file, something that I'm going to fix in the next version.

What's the file 00000000.dat you attached and why did you try to open it with quickbms?
It's not a rpa file.
If you got it from the extraction of the rpa archives, it's ok. I noticed it too and in fact there is a nameless file as first file. You get the same result by using the python version of the script.

[aluigi]

Ah ok probably that file you attached is directly the TOC.
Let me check.

[aluigi]

pickle.bms 0.1.2, there was an opcode (GLOBAL) not instructed to read data

[bugmenot]

Both rpa_renpy_nopython.bms and pickle.bms must be in the same folder yes.

Yes but I had renamed the pickle one so it wasn't working with ether one of them.

Great work, thanks but it seems there is more opcode's missing: Error: unknown opcode 0x00000088 at offset 0x000011d1

[aluigi]

Yes, you are right.
pickle.bms 0.1.3 and I have also changed one word in rpa_renpy_nopython.bms 0.2a due to a modification of the pickle script to avoid problems with the variable names of other scripts using it (currently none).

[bugmenot]

Shouldn't OPCODE PICKLE_NEWTRUE be DATA = 1 instead of 0?
