| `gsmrf` | Rewrites message at the moment when Game DLL attempts to write an internal engine message, usually specific to GoldSrc protocol. Right now only supports `svc_spawnstaticsound`, more messages added by request. | * MetaMod/AMXModX based mods |
| `sp_attn_none` | Makes sounds with attenuation zero spatialized, i.e. have a stereo effect. | Possibly, every game that was made for GoldSrc. |
