@nyaoouo did you managed to have it working ?
If it's not the case could you try with pymem==1.8 and report any success // issue ?

I am having the exact same issue with the same code. I tried the above solution; it did not work. Please help.

Hi I'm having the same issue. I keep getting: %x format: an integer is required, not NoneType
I also used the tutorial code on Pymems read the docs website to ensure i was writing it correctly, also tried restarting my laptop to ensure that there were no conflicts and yeah it sucks.

hope you guys can help
