Castlevania Order of Ecclesia problems

Dunno what's wrong... I took my previous save (finished already) and tried to load but the game freezes (I can see the status on the top screen only)... and if I try new game the game suffers the same problem after you equip the rapier in the tutorial...I tried using R4 1.18 and that YSmenu (I got to play Mario and Luigi 3)... but in both I had this same problem...
and no, there are no cheat codes on it!

Backup all your files and reformat your MicroSD.

done it and working... thanks ;Dbut when I put another rom in the card (Mario and Luigi 2 and Gyakuten Saiban 3) it stops again :Pit's not the first time a game stops working because of another rom... is there any motive to happen this?
