Miyoo mini Psx and ds games not showing in games list.

I also tried the workaround by making a Playlist in retroarch and the games won't boot not sure what else to try

So far ALL my gba and GBC games show up and run fine.

VERY new to emulation on hand helds but I've been doing it for a couple months on my phone. No idea how to fix this.

Note: I am using the psxonpsp660.bin bios and put it into the bios folder. Didn't rename any folders.

Update: got psn games to work by turning my games into CHD files

God DS games to display. But they won't launch. When I try to launch them I get a black screen that hangs for like 2 sec and it boots me back to game selection.

If anyone knows or has had this issue before please help
