Can't get psx emulator to work

I have the bios but wben i try to open up games it doesnt work. What should i do to fix the problem?

We need more information than that, preferably a log. Also, which platform are you on?

Im using my antroid phone. I have tried mutiple games but none have worked. It either goes back to the main page or just sits there with the overlay but nothing ever happens. I have tried it with a bios and without but that didn’t do anything. Is there a certain folder or place where the bios should be?

I believe it should work if you put the bios in the same directory as your disc image.
