Note for updating patches

ChangeSubclass

Found by search string "CS2 does not support changing entity subclasses." and patch the jump condition

EmitSoundVolumeFix

Found in the internal function called inside "EmitSoundFilter",

at the bottom, theres a hash 0x2D8464AF ( which is the murmurhash2 hash of "public.volume_atten" with seed 0x31415926 )

patch to change the hash to 0xBD6054E9 ( the murmurhash2 hash of "public.volume" with seed 0x31415926 )

TeammateCanBlockGrenade

Found in a function that modified CBaseGrenadeProjectile::m_bHasEverHitEnemy,

get the offset of m_bHasEverHitEnemy in schema system, and use Find immediate value of IDA to find that function,

then find the similar code like this:

if ( (*(unsigned __int8 (__fastcall **)(_QWORD))(*(_QWORD *)v13 + 1376i64))(*v12)
    && (*(unsigned __int8 (__fastcall **)(__int64))(*(_QWORD *)v13 + 3376i64))(v13)
    && sub_1806F4E40(v2, v13) )
  {
    projectile->m_bHasEverHitEnemy = 1;

The third condition is the function that return if two player is not teammate patch that condition to remove the check
