[HELP] Action/list.csv

Yeah, it's lines. The crash occurs when there is an allocated buffer for names with a constant size. Each name has 0x100 bytes reserved space. When more lines are added more space is needed for the lines (names).

So for each line, the executable sets the write position +0x100 bytes from the previous one. At some point this will result in moving the write point past the allocated memory, and then the executable tries to write into zero memory, causing an access violation error (0xC0000005).

EDIT:

Could someone post the latest dekaron.exe you people use (I got my own but it's unlikely it works on your clients + I don't really want to share it).

I'll edit the posted executable and someone can test it. :)

When it comes to editing the .exe, thers no such thing as making an "easy" tutorial. The best tut outta there is probably lena's reversing tutorial. Just google it.

I'm still working on it, you need to understand that editing executables is not like writing a text file...
