Hacking Pygecko: how to run OSFatal?

[H0neyBadger]

Hello,
I try to run the OSFatal function from pygecko.
I tried the following code, without success.

tcp = TCPGecko("192.168.1.1")
OSFatal = tcp.get_symbol('coreinit.rpl', 'OSFatal')
print(OSFatal("hello pygecko"))


Traceback (most recent call last):
  File ".\hello_world.py", line 42, in <module>
  print(OSFatal("hello pygecko"))
  File "C:\wiiu\libwiiu\pyGecko\tcpgecko.py", line 353, in __call__
  return self.rpc.call(self.address, *args) #Pass in arguments, run address
  File " C:\wiiu\libwiiu\pyGecko\tcpgecko.py", line 241, in call
  request = struct.pack(">I8I", address, *arguments)
struct.error: cannot convert argument to integer

Then I tried to convert the python2.7 string into integer, but unfortunately system crash in a mess of pixels.

Somebody have an example of python code?

print(OSFatal("hello pygecko"))

This is the error I believe.

You don't do it like that, OSFatal() shouldn't be nested in a print() statement.

The nested print doesn’t matter. It print the value returned by the OSFatal function in python console.
But thanks for the advice.

I never looked at tcp gecko....Is OSFatal in tcp gecko?
I don't see any Imports being called.
If you are just looking for examples here is a fun place. http://www.tutorialspoint.com/python/python_modules.htm

No, OSFatal is not in tcp gecko. But pygecko allow us to run rpl symbols through python code.

Indeed, I often forget the imports in my code samples.

from tcpgecko import TCPGecko
tcp =TCPGecko("192.168.1.1")
OSFatal= tcp.get_symbol('coreinit.rpl','OSFatal')
OSFatal("hello pygecko")

There is no need to import OSFatal since the get_symbol return a function.
I have good knowledges in python. And it’s probably my main problem because I don’t really know others languages (and English is the first one)

Yes, This file is basically the (partial) source of pygecko. https://github.com/wiiudev/pyGecko/blob/master/tcpgecko.py

The examples provided in sources are based on pokemem or readmem.
https://github.com/wiiudev/pyGecko/blob/master/octoling.py


The most significant example of symbol import can be found in FS* functions
https://github.com/wiiudev/pyGecko/blob/master/tcpgecko.py#L147
https://github.com/wiiudev/pyGecko/blob/master/tcpgecko.py#L161
I think I have to work from this base.

But if somebody has the solution … any help is appreciated.
Thanks a lot guys!
