Thanks, I will give it a try.

Thanks for the alternative way, but I already converted everything with the method above. I just have one more question: I have all the .bin and the .cue in a seperate folder in .../roms/psx so it looks like this http://i.imgur.com/CpD2oTW.png And then I launch the .cue in Recalbox. Would it also be possible to merge all those files into one .bin? It would look much better visually instead of having 3 files listed for one single game in Recalbox.

Thanks for all the replies, it helped a lot. I converted all the files into .bin and added the .cue files. It seems to work now. Next step is to store the ROMs/ISOs on my NAS and play them directly form there, because my Raspberry Pi 3's SD Card doesn't have enough storage. Maybe someone has a good tutorial for that? I googled around and wasn't lucky to find a good working tutorial. Thanks again. :3

Hello everybody, I just installed Recalbox on my RaspberryPi 3 and downloaded some psx ISOs. Most of the games came as filename.bin.ecm and I used ecm tools to create .bin files. Now some other games came in folders with one filename_(Track 01).bin.ecm and some more filename_(Track 02).ape, etc. How and where am I supposed to use these .ape files? Thanks in advance! :3
