Visual Boy Advanced Error Help

[indecentKAOS]

When I try too open up one of the games for my visualboyadvanced...I get an error message that reads:

ERROR
Unsupported BIOS function 0d called from 0810e406. A BIOS file is needed in order to get correct behavior.

Now, once I press OK, the game works and everything but sometimes the controls get all haywire and messed up everynow and then, im pretty sure that's what the error message was talking about. Does anyone know what I may do too fix this?

Btw, I already have the latest DirectX

I believe that you are using the internal bios.... Try to find the real GBA bios, refer to google.

I've moved this to the Nintendo forum. Please don't post questions in the feedback forum, it is not the right place.

Thanks
