Wii Retroarch - NEC PC98 / np2kai core?

Is this core available for the Retroarch on the good old Wii? It’s listed as a supported core in some websites, but I can’t seem to actually find the core for np2kai in any of the Retroarch-Wii files.

Perhaps people got it mixed up with the cores on the WiiU port?

The core np2kai (np2kai_libretro_wii.dol) it’s available in the version RetroArch 1.6.8 and 1.6.9

I do not know if it works
