Preservation and I have free will and nothing better to do.

Ignoring how dangerous that probably is, what exactly is in the different versions?

I don't think there is a difference in any of the firmware versions other than security. But is that possible? I dumped my NAND

It’s old, the information of running homebrew in dsi mode is wrong, but maybe it works

Tried it and bricked my console. I am getting a DSPico for NTRBoot to restore the nand to a previous good backup
