Basicly i have been trying to mod the gpd for mw2 for over 5 months, well not every single day but mostly. I have been knowing this for a long time and this is the answear to everyone complaining about the no recoil.

When you mod the no-recoil your changing the sensitivty to "0" and with 0 sensitivity you wouldt be able to look up or down left or right (x,y) axis. since you dont got a sensitivity you not able to move just as simple as that.

I've been doing some stuff with sensitivity modding and putting 5E instead of the no recoil one (7F) would make the intervention scope almost look like your aiming up and down.

Possibilites: There is a way to get /no spread = bullet goes straight and its not no recoil. But would require alot of decoding and other information, what to replace and what to search for.

possible ireapzz/xdarknesss could of had achieved this: ( just a theory )

And the code at top begin of an GPD called XDBF = ID of the game to be recognized.
