Hacking lives on "I wanna be the cat"

Post by Cowtow » Sun Dec 24, 2017 12:28 am

Hi there,

Im trying to get unlimited lives on a I wanna be the cat, but doing a direct search for the value hasnt given me much in the way of results. Using the "unknown value" and then searching for changed value has yielded a view results, that count upwards when i lose a live, but not in a consistent pattern, and most of them crash the game if i attempt to freeze them.

I narrowed down a few of them that might be it, and checked what wrote them, only to find that noping that out led to a crash. An example of what most of them look like would be:

But ive honestly go no clue what to do from here. Does anyone have a suggestion?

You're debugging the internal byte read/write function of the engine (Goggle V8 JavaScript engine) That is not a place you want to modify, or it will as you found out, crash. You should backtrace further to find out where the bytes came from.

You can't use the debugger for java games. (Ask DB :) )
Download Notepad++, download JSTool plug-in and edit game files.

I hate to ask for more help.. but exactly what should i be doing next?
I followed your instructions and went to the game files, but upon closer inspection of the ones actually located in my program files (and appdata), i couldnt find anything that looked like it was a JavaScript or JSon related file. Im not sure if im just looking in the wrong place or if im not understanding the filetypes to be looking for.

You must search in game folder/dir for something like (folders) data, www, js etc.
Java is not "my lang" so i cannot tell you how to edit files.
It (maybe or not) looks like:

Thanks again for the quick reply! I think i found the issue and perhaps discovered that it its above my head (i guessed that java wasnt quite your thing when you started talking about java and JavaScript as the same thing ;).)

It appears that the game is made using a platform called node.js, a platform that allows for javascrpit (web) based applications to be run on your desktop as an exe. Problem is, with nw.js games, i dont think anyone has yet figured out how to just extract them, edit the information, and then recompile them that easily based on other semi-recent related topics:

Atleast, there isnt any info on it in cheat engines forums.
Thanks for the help again Blayde, i probably wouldve spent days on this without you :D
