Hacking Pokemon White 2 Freeze

[sjmaco]

My patched Pokémon White 2 is freezing repeatedly on the same spot on M3DS Real Latest Sakura Firmware... It's always when getting through to Raimon City (Elesa's Gym City), getting through Join Avenue. It shows a black screen with the music still playing...

Any ideas as to why is it happening? Or how to fix it? Thank you all in advance.
