Here a working test plugin. For a first version, it will be enough.
It includes a configuration file to customize more easily (custom_footsteps.ini).

Installation :

- Unzip the package in amxmodx/ directory. The package contains everything you need.
- Declare the plugin in plugins.ini.
- Configure & restart. (By default and for testing purpose, all the original sounds are replaced with the snow sounds).

That's all.
There are some comments inside the sma.
