im still fairly noobish but i think i can shed some insight
idk what operation7.exe is so im going to suggest something easy (everything here is freeware and open source)
1.download/install Cheat Engine(or Ollydbg both have the same capabilities)
2.download/install AssaultCube
3.open AssaultCube find your health value using olly or CheatEngine [I Recomend CE because i find it would be better for people starting out due to ease of use](its only a 1 tier pointer so nice and easy to find)
4.take that address find what points to it and thats your main address (thats the one manipulates your health)
5.write down the the ADDRESS and the OFFSETS!!!
6.start a empty win32 app create a base that makes sure that the game is running and for a user interface (This will be a trainer but its still a hack
)
7. edit your bytes and such
8.give it a test
