The process of extracting certificates from a retail cartridge and injecting them into a ROM technically violates DMCA anti-circumvention laws. However, for a user who owns the original cartridge and is creating a backup for a flashcart, the legal argument falls under fair use parody/backup (depending on your jurisdiction).
For years, users relied on a brute-force solution: forcing the ROM to boot in standard DS mode via AP (Anti-Piracy) bypasses. However, this often led to graphical glitches, slower performance in double battles, or crashes in the Pokéstar Studios. pokemon black 2 dsi binaries fixed
The breakthrough came when members of the DS scene reverse-engineered the DSi boot process. They discovered that by extracting the known good DSi binaries from a legitimate cartridge dump and re-injecting them into a clean ROM, you could trick the DSi/3DS hardware.

This resulted in the colloquial term: "Pokemon Black 2 DSI Binaries Fixed." However, this often led to graphical glitches, slower
It is important to note that this is not a "crack" in the traditional sense. It is a repair of the cryptographic signatures. When a release group or patcher says the binaries are fixed, they mean the ROM now contains valid signatures that the DSi bootloader recognizes.
