When starting core with no content, boot the BIOS

[anyputer]

When you start the core without content... it should boot into the BIOS! :-)
I don't think it would be that hard to implement, but I don't know much about Libretro / C / C++ .

I feel like changing the variable "DirectBoot" to 1 when started with no content could do the trick? And 0 if loaded WITH content?

does upstream feature that?

[anyputer]

Yes actually! =)
You can just go to System -> Run in the menu :D

But turn this off first:

I guess that counts?

[anyputer]

Still no response? man!
EDIT: I literally didn't mean anything bad, just wondered why no-one responded.

Sorry that all the hours we put into this project as volunteers (for free) don't fulfill your expectations.

Whoa, I didn't mean that! I just wanted to know if such thing is possible. I am greatful for all of the time you spend into these projects! :(

You can create a copy of the nds firmware file and change the extension to .nds, then select it as the game to load when running the core.

It will boot into firmware with no game inserted.
