Megaman ZX Advent freeze problem?

Whenever I get to a certain point near the end of the game, it just freezes on me. All the time T_T Is this a ROM problem thats happening to everyone? Or just me...?

BTW Im not using a DS emulator, Im using an R4 on my DS.

 

When does it freeze ?

I played the game using my SD rumble version, it doesn't have any problems so far.
Just the voice conversation it seems a little....., y know, unclear. (i post this problem btw)

Oh, i'm almost the end of the game.

Maybe u should check ur software & firmware, or maybe u should update ur dsq frequently
like what i did to my Megaman Star Force : Dragon. (just an advice, give it a try)

 

my problems a lil defferent...........when i use my rom on my ds (i use the ds extreme)it doesnt even start on the start screen it just goes black and says "the ds gamecard has been removed"...........any help a rom link ??thanx..........cheers!
