EMUELEC and Sega Saturn

[lmasaf]

Hello, everyone. Sorry for writing in english, but I'm having a problem and I don't know how to solve it.

I have a saturn emulator on a TV Box with emuelec, and I can play saturn games but only european versions, how can I play american and japanese versions? I'm pretty sure I have all the bios in the correct folder, but when I try to play american and japanese games it goes to the sega saturn system and keeps saying "Drive Empty"...

Thanks for the help in advance!
