i'm not sure what most other people uses but i find that with psx there are many .bins for a game iso. usally a .cue is in cluded with the .bin. when you places a iso for psx in the rom folder all the .bin shows up with it and its sometimes a real pain to set down and hide them all. If the .bin was hidden the files would not show up. Would make things easier for other people. a quick google search will show people with recalbox has the same problems.
in fact i reenabled it because most of ps1 roms are .bin, so people had it not working anymore.
In all cases, it seems that's not the best for all.
cool, it's not hard to hid the extension. I'm not sure if you can put it in the option or not, kinda easier for some people. Tomb raider have 40+ .bins But anyway keep up the good work. Your doing a great job.
