Fixing Wireless Communications
Each firmware copy contains WiFi board specific data that lets it connect wirelessly. This data cannot be moved from one WiFi board to another, or you will be unable to connect online or in multiplayer games. To solve this, we will back up the original data and copy it over to the new firmware we’ll be flashing.
1. Dump your DS firmware with DSBF_dump.nds. (use a flashcart for this)
2. Open the dumped firmware in a hex editor. It will be called something like "FWD7F1EE.BIN", and is found on the root of your flashcart SD card.
3. Select offset 0x2A to 0x1FF and copy it.

4. Open the new firmware in the hex editor.
5. Select offset 0x2A to 0x1FF on the new firmware and paste the data from before.
6. Save and overwrite the edited firmware.
Well, all DS parts are super-hard to get nowadays. I tried looking for a replacement battery and almost everything I found was a bootleg, and I don't think that I'll be able to find a wifi module under the cost of just purchasing another DS.You can always change the firmware, but
BE CAREFUL!
Before you flash anything, dump your firmware. Your original firmware has a small region of data specific to your wifi board. It is entirely unique and can't be reproduced. YOU NEED TO BACK IT UP. See below:
If you ignore this and overwrite that data without a backup, you will never be able to do local play or online ever again without replacing the wifi board entirely. There are only so many replacements out there so be careful.
An OG DS has more to gain from a firmware update, but even that can be done through a flashcart, i.e., increase the brightness.There is not much to gain.
Installing FlashMe can get rid of the Health&Safety screen as well as some obstacles not important anymore (DS game loading from SLOT-2 devices, disable signature checks for Download play).
Not necessarily hard, but it'd cost you the price of a used or for parts (whether untested or somewhat broken) and yeah, it wouldn't be worth it.Well, all DS parts are super-hard to get nowadays.

So thank you for the instructions.
