hello. I have a video on my channel explaining how the format transformation is done. It is in Spanish but it is well understood, it is very graphic. I recommend that you play the games in iso/ogg/cue format as they run better (the video shows the conversion to that format). if you want to convert them to bin/cue use ultraiso. it's free (click on the evaluate option) simply when you open the program click on tools and then on convert... there you can see the format options. but I already told you that the recommended format is iso/ogg/cue. on the other hand if you play on tv crt I recommend the cores of pc engine and pc engine cd of retroarch hexaeco ss that you can find here in the forum. a greeting
