system can't be hashed

[ricardoclaus]

Hello people,
Sorry about my English.
Does anyone have any tips with the problem below?

I'm having trouble creating hash from roms in Recalbox 6.0 Raspberry pi3.
Systems like Mame, FBA Libretro and NeoGeo do not hash, the other systems hash normally. I don't see any errors on the screen.
I see this information in the logs:
/recalbox/share/system/.emulationstation/es_log.txt

My goal is to play online with Netplay. Looking at the Recalbox wiki, it is informed that NeoGeo, MAME and FBA systems do not need to hash to play, unlike the other supported systems, such as Mega Drive, SNES and etc ...
