Hacking R4 DS Master System Problems

[Nenah]

I have uploaded a Master System Emulator onto my R4DS, and it works sucsessfully, i was able to play Alex the kidd with no problems until i saved it. I saved my progress and it said save sucsessful, but when i ask it to load it never can and says there was an error, please may someone help me? all this is stressing me out way more than it should.

Ah another problem i have, my SNES games constantly crash :-S anyone have an answer to that?

Thankyou
