Help with these games

3504-Avalon code
Zenses
3551-Scrabble
3552-Henry Hatsworth
3461-Peggle dual shot
2689-Final FantasyI downloaded these Roms and none of them work for me, It says something about sav data not being found. Is there anything else I need to move from the rar file to my R4?? Thank you.

Whenever asking for help with DS roms, you should mention which flashcart you have. It sounds like you may have an R4 though? Anyway, what you need to do is an arm7 patch. If you search the forums for it I'm sure you'll find out how to do one. If not, try the gbatemp.net forum.
