Need to modify R4 .sav file for bw2 challenge keys

munchkn77 · Feb 17, 2025

I've been at it for days, trying to do this one thing. Have a cartridge R4'd version of Pokémon Black 2 and want to be able to edit the .sav file to input 'challenge keys' in order to be able to restart the game with challenge mode unlocked. Not recognized by tools such as CheckPoint, PKSM, etc. Used CheckPoint to create a .sav file but can't find any tool to modify it.

Willing to just buy this game with challenge mode unlocked, but just don't know where to go or how to do this.

So, does this mean you have a flashcart with an actual microSD card inserted, or is it some cart that's been flashed permanently as Pokemon Black 2?

Because if there's a removable microSD card, you should be copying the save data off of that instead of using Checkpoint.
