'inject' Modes to gta_sa/SA-MP??

[redex]

hi, i am working on a custom SA-MP launcher for my server, its an anti cheat now i want to do something more, i want to add some modes and stuff, like skins or other modes, now i want to it only load when user is opening gta_sa with my launcher, so i dont want to just put some stuff in game folder , how can i do something like injecting that files ? for example i just downloaded a mode that have 2 files , tff and dff (if i got that right) how can i inject this model files to game? or another example i just downloaded a radar mode, it said i should replace the IMG files to gta3.img , how can i do that ONLY when user opening game with launcher?



i seen this thing in other servers so i guess its possible, by the way i used C# for the launcher
