You need to paste this code in NewUIHotkey.cpp and create new bool Borderless and change it from g_pOption->Borderless to your bool.
DWORD AltEnterDelayTime = 0; - also create this DWORD.

If you don't know how to use and import this code - better learn programming more. I will not answer any questions related this. Just making my first contribution.

Can you share your 5.2 widescreen code? Thanks
