@alexander-tolstykh What do you mean it's not working ?
After you placed the file mame2010_libretro.so (contained in the ZIP) in the /usr/lib/libretro folder, what did you do ?
The core needs to be declared in the system to be usable. If you don't want to bother modifying conf files, the best and simplest way to achieve integration of mame 2010 is to replace imame4all with it (imame4all is of very little use compared to mame 2003 (aka 078) at least regarding games supported) .
In the folder usr/lib/libretro, spot the file named imame4all_libretro.so and rename it to imame4all_libretro.bak, then rename your file mame2010_libretro.so into imame4all_libretro.so and you're done !

When you need to execute a specific game using mame2010, select it in the list, then hit SELECT button and "EDIT THIS GAME" option and in the drop-down list of libretro cores for mame select mame4all. Save your modifications and .... VoilĂ  :=)
