ForlaxPy 14 Posted August 16, 2019 (edited) [*] Changed the text How I did it? Spoiler Simply by breaking the runtime in this address: 00CA675B then you would be able to see the text in the edx register, so I changed that text from memory dump as you can see here [*] Added +1 to sum factorial How I didt it? Spoiler Same story go to 00CA5070 and edit the eax reg For now that the addresses are well know you can easily calculate the string value and change edit these reg values by patching the exe so it always return what ever you want.
