mame roms not showing

[blackcat88]

I have a problem with my recalbox.
I configured a raspberry pi4 b with recalbox 9.0.
I copied some roms in shared/roms/ for specific enviroment ant they all works except for the mame roms.

I copied some mame roms multiple times with bios, ecc..but they are not visible in the list except for 4 games (grindlee, looping, supertank, robby roto).

I tried also to set "update game lists" but I didn't get any results
What i am missing?

Thanks

I had to zip all mine up to get them to show. Not sure if this helps but it helped me.
