Super Game Boy 1/2 bootrom dumping support

[DrAzathoth]

Is it possible to add support for dumping the SGB1/2 bootrom (BIOS)? I understand this is fairly unnecessary as it doesn’t have a splash screen and most emulators that support the SGB just HLE the bootrom. Personally, I would love to dump it for archival purposes and more accurate emulation.

Personally I would like to dump this too (no idea if it is possible though) (also assuming this is different to the rom dumped already?)

The bootroms have been dumped. The only real difference between the SGB and SGB2 is that there is a feature that allows games to distinguish between the two (like the two different borders for Tetris DX).

There are some prototype SGBs floating around though, most notably one with SGB-CPU X1 that hasn't been dumped. Though I am not sure how one would go about dumping it. Well, aside from this.
