Ask for help on ecc pubkey replace example, thank you!

[prospect2005]

The attached is a demo and its license format. I will appreciate if you could show me how to replace the ecc pubkey code and make it work. I downloaded some ecc pubkey replace tools. However, they don't work well.

I can patch and run it successfully. I just want to learn how to replace the ecc pubkey code. Thank you!
