# dsbf_dump
This homebrew can dump the Nintendo DS BIOS and firmware from a Nintendo DS, DSi and 3DS with a Slot-1 flashcard or a Slot-2 flashcart.
### Usage
1. Get a flash cartridge that can run NDS homebrew.
1. Download `dsbf_dump.nds`, place it on your SD card.
1. Run the app, and it should place your BIOS and firmware in a `FW############` folder on your SD card.
- Replace `############` with the MAC address of the device
### Usage (IS-NITRO)
1. Download `dsbf_dump.nds` and rename the file extension to `.srl`
1. Load the app into IS-NITRO-DEBUGGER
1. For each section that is dumped:
- Use the debugger to dump the memory contents
- Find the area with `0xDE`s, this is where the dump presides. Cut off all the parts before and including the `0xDE`s
- Find the area of `0xAD`s, this is the end of the dump. Cut off all the parts including and after the `0xAD`s
