the folder structure seems always be the same:
YourGame123\PS3_GAME\USRDIR\EBOOT.BIN
YourGameABC\PS3_GAME\USRDIR\EBOOT.BIN
use gamefolder as "romfilename"
This should do it (untested):
executable C:\attract\EMU\PS3\rpcs3.exe
args C:\attract\EMU\PS3\ROMS\[name]\PS3_GAME\USRDIR\EBOOT.BIN
rompath C:\attract\EMU\PS3\ROMS
romext <DIR>
