Freezing in Pokemon Platinum at Spear Pillar

After beating jupiter and mars, the game freezes right after Cyrus summons up dialga and palkia. Although the game is still running, nothing happens. I'm using nocash. Thanks in advance.

Use the latest version of No$GBA, version 2.6a. Use No$Zoomer as well if needed.
