How to Create the Pokémon Black/White 2 frieNDS Rom from a Good Dump

It's funny how PokéCommunity and Project Pokémon each represent one extreme side to take on the same issue. On Project Pokémon, if a romhack contains even a single unaltered byte from the rom, it gets taken down. A lot of Pokémon Super Mystery Dungeon hacks are lost forever because of this. Meanwhile, PokéCommunity is on the other extreme; they have no problem allowing a romhack that asks users to pirate a bad dump of the game. Romhacks like these are impossible for people who legitimately dump roms from their own cartridges to use... unless you are using this guide :)

Here's how to take your good dump of Pokémon Black 2 (CRC32 d4427fd1 when decrypted) or White 2 (777eb04f) and modify it to match the frieNDS bad scene dump (Black 2: 25ba3aa6, White 2: 95ab5437):

1. Open your rom in a hex editor.
2. • Black 2: From address 0x11880000 to the end of the file, fill every byte with FF.
   • White 2: From address 0x11800000 to the end of the file, fill every byte with FF.

The last time I made a post like this, I explained some things about hex editing.
