In the Japanese Pokémon White, the game freezes before the cutscene wherein N summons Reshiram. Don't have this problem with Black. I'm using the latest version 1.22 and a clean ROM.
I'm still facing trouble with Pokémon White. Right before the cutscene with N summoning Reshiram, it locks up and you can't get any further, even with this latest firmware 1.22. Using the original R4. I don't have this problem with Black, though.
I've got this strange issue with the White version on Wood R4 1.22. Everything works fine, no freezes or issues or anything until near the end of the game. When the cutscene with N summoning Reshiram is supposed to start, it freezes. It's a clean ROM. The funny thing is that I didn't have this...
