QUESTION
I got this byte-string from the BizHawk-Emulator via comm.socketServerScreenShot(). I understand that it's an PNG and hex encoded. So I tried to decode it (whole and splitted string), but there are some invalid hex numbers (?).
But how do I convert it into an useable image?
I also read this page about PNG and I understand some of it, however, not how I can do a "reverse hex dump" of the string.
A txt of the img: HexImage.txt

Answered 2021-Aug-09 at 20:48The issue you are facing is most likely due to character encoding issues. If you store the received data in a variable, Python will interpret the \xNN
values as characters and as such they need to be encoded before they can be saved to disk.
The choice of encoding will write different data. Normally you would like to store your data as "utf-8" (standard in Linux and most portable) or perhaps in some kind of windows format, e.g. "windows-1252". In this particular case, though, we are not dealing with text or symbols, but rather with raw data. Therefore neither of the codings above will give a correct, working output. What is needed, is rather raw_unicode_escape
since this will encode the characters without modifying the underlying bit patterns.
Thus, to store the image, we need something like:
QUESTION
I'm in the Lua console of the Bizhawk emulator. I want to edit Ram of a GBA game.
I have a directory with a Lua file and another folder, that has a text file in it. I managed to read text from it by using the absolute path but I want to make it work with the relative path.
I tried to use arg[0]
to get the path of the file but it's nil.
And this outputs me 'ain': debug.getinfo(1,"S").source:sub(2)
