Alright. Must have over-read that part.
You have to first understand that programming RPM/WPM hacks takes a long time to master. Don't expect to start Monday and have a working hack by Friday.
That's not going to happen (Unless you're Einstein)
Download Microsoft Visual Studio 2015 (Just Google it, they have a free trial afaik)
Get some public hack source (For DayZ, obviously)
Open the VS project (From the source files) in Visual Studio, take a gander at the code for however long you like. (1 minute, 2 years, meh)
Change some stuff, update some offsets (Use Reclass 2013 to grab offsets or ask Mythicalll for his offset grabber lel)
Now disable the BeDaizy.sys driver with processmanager, hop in a Non-Battleye server and run your hack, play around.
When you get really experienced you can learn driver stuffs, disable the root-kit and use your hacks in BE servers.
Start with something simple like no-grass source. (Not on this forum doe)
