I just found it through the windows explorer interface (connected through the network) into \share\arcade\libretro

I don't understand why I was not able to see them when looking from the SD card directly

Hi,

I am searching where to find the MAME 2003-plus original dat file to be used with clrmamepro.

I am using Rpi4 with the latest recalbox version. This is a fresh install

/share/arcade is empty
/share/bios/mame2003-plus has only cheat.dat and hiscore.dat
/share/roms/mame/mame2003-plus has only a .keep file

I don't find the right place after several hours looking

Thank you for your help,

Greg
