Scurge Hive DS Issue

Hi guys, I'm playing right now Scurge Hive for NDS.. Great game, but it seems to not work properly.I'm half way through the game and I've reached this new boss: in this game bosses have a life bar that you have to empty 4/5 times to kill them (how original, lol).
In my first attempt I've emptied the bar 4 times, the bitch was almost killed, but then it killed me, so meh, I tried again. And there's come the issue.Any time I try to kill this boss I get to empty his life bar once then the game freezes suddenly.
If I mess around in the level not looking for the boss the game runs just fine.I don't know exactly what to do.. The rom file worked fine until now, and I don't think it's some kind of anti piracy since it's HALF WAY through the game.I'm pretty depressed guys, can anybody help me?I have a R4 flashcard, but the game's worked well until this specific point.

YSmenu
Confirmed working with YSmenu.Guide to set up YSmenu for R4 Clones:

I am already playing through YSMenu :\

Try redownloading. May be corrupted but it should work with YSmenu.

Looks like there's an update.. :\ I'm trying to plug the flash card in the USB but it doesn't work. The icon of a new removable disc appears but it doesn't let me open it.Is my flashcard fucked forever? :|

Nope,
I have a r4 to and I had this problem once.Just keep trying,
it will work :pAnd if it doesn't work, you can go buy a new micro sd card,
it isn't neccesary to buy a new flashcard.
