Possibility of a screenshot feature?

[Powerlated]

I am wondering if the possibility exists of adding a screenshot feature to open_agb_firm. Not only could it be a cool feature, on-device screenshots would drastically lower difficulty for those wanting to run tests to reverse-engineer the GBA PPU.

This is basically already in but i removed it in the last build. It dumped the raw frame from LgyFb (basically the capture card) output. png is not easy to do and would increase code size significantly.

Is there any need to use png? It'd be a lot easier to create a bmp file and just ignore compression

bmp should be doable.
