This is a NDS Bios Dumper. Credit must go to Loopy, Costis, CaithSith&Martin Korth for finding the hole/code example to dump the ARM7 bios. It will write the ARM7 BIOS to GBA SRAM 0x0000&ARM9 BIOS to 0x4000. Save 0x0000 ->0x3FFF as BIOSNDS7.ROM&the 0x4000 ->0x4FFFas BIOSNDS9.ROM for it to work on No$GBA. It only comes in ds.gba flavor as it needs a GBA cart to write to.
