boot_loader_wsc_bfont.bios ?

Would that allow booting the DS core from either SD or IDE too?

Yes.

And could you say roughly which address ranges your code was injected into?

Syscalls I get from memory of my console (PAL version).
Fonts from US version. But I think it's not important.
The first 16 KB of BIOS this is a Bootstrap with simple font. After there binary of boot loader. And at offset 0x100000 begin original fonts.
At startup Bootstrap, it's setup some regs and syscalls (only fonts work, other syscalls is dummy), then load and execute Boot loader. At Boot loader startup, it's setup original syscalls from internal romdisk (16 KB memory dump) and begin works...
So it's fully custom BIOS, not hacked original.
