Is it possible to change this things: SfxBegin: Weapons/Player/Misc/Single/g3_fire SfxNoAmmo: Weapons/DryFireFromManuallyCockedHammer SfxReload: Weapons/weapon_reload_standard PfxMuzzle: MuzzleFlashDouble ? And may be there is some way to add new models if i want to add new items to my server? Like models of projectiles or other parts.
You can unpack them with some tools, but i am not sure about license agreements about this and also you will have the problem how to pack all this back...
I don't think they would have left old models in, since the new models use the same names (and probably ID numbers). No one can prevent you from using google with wise keywords. Asking this on the forum is not the best idea.
Forum is good because it store all roadmap of the problem )) May you please add some more explosions to bundles? And not sprite, but 3d please, there is 2020
This was more related to your mention of "license agreement" than to info tracking... because yes, there are tools for this, even tutorials.
