Carnival Games save error + SpongeBob Boating Bash White Screen

Hi, I hope I can get some help. I got these 2 games that are the only ones that don't work on my R4 NDS. The Carvinal Games doesn't load because it comes up with a save error. I tried many methods on this forum like DS lazy and unpacking etc but it's all too technical for me. Could someone give me some help with Carnival Games fixing the save?

And on Spongebob Boating Bash, the game won't load, just freezes on start.

hope someone can help. Thanks.

 

Bump - Also i can't get crossword ds to work on my DS lite with my r4i (r4 update) http://forum.romulation.net/index.php?topic=29975.0 it loads the game and when you press start game or training it sticks on white and still plays music.
