It's famous bug in (E) version with that freezing after battle with frogs.
Fix:
1. Use DSLazy.
2. Load the rom.
3. Unpack it.
4. Replace file \NDS_UNPACK\data\Apl_Kit\op1.fds with op2.fds for example.
5. Pack rom.
6. Enjoy.
op2.fds is "titles" file. So you can use it without fear of spoiling...
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
