Flashing GBA BROS

[Hawkeyefile]

I was wondering how do I flash my GBA's BIOS?
I dumped the BIOS, and applied the no intro ips patch to it. Now all I need to know is how to add it back on the physical GBA. I use Supercard SD if that helps any.

I'm pretty sure the GBA BIOS is part of one of the main CPU chips, and as such it cannot be overwritten. My guess is that the IPS patch was probably made for use with a GBA emulator like VBA, where you can opt to use an actual BIOS file if you feel so inclined.

I could be wrong though, but I don't think you can modify the BIOS.

I read somewhere you could.
