GBA ROMs Lagging / Not playing great???

Bios-File installed?

Well thats included in Raspberry Pi image.

Heuu, no, the bios file is not include in any image of retropie

So I flashed a new SD Card (8gb) with the zero image from retropie website. I made the relevant changes to config.txt to make the audio work. I'm still dissapointed that GBA games don't work without sound lagg. Does anybody have GBA working perfectly?

The games wouldn't run at all without the BIOS though? So I have to DL and then drop the BIOS into gba folder? I never had to do this before and GB and GBC run OK. So does NES.

UPDATE: I placed the bios in \\RETROPIE\bios but still same sluggish performance from GBA games

Only some cores have need a BIOS file -> wiki
Can you provide a save state where the problem appears?

I have the GBA BIOS but the games still aren't running perfectly. What I want to know, is it even possible to have GBA games running perfectly on pi zero w? Its annoying me because I don't know if this is normal or not. If not, then I am very dissapointed that I cannot play gba on my raspiboy. One of the main reasons I got it, so will probably sell it.

Watch some GBA games performing on a pi zero on YouTube. I did that too, but also expected to get a little better performance due to the small resolution.

Sure, it probably will never perform like a pi 3.

I also noticed this, but then realized I have to press A and select lr-gpsp as default. After this every gba game runs smoothly.

I recently have the same problem with running homebrew games from here and the PD Roms website. The games are pretty small with low graphic details but I am experiencing a lot of lag. Not sure what is causing it and why this is happening.
