Pokemon Mystery Dungeon Exploers of Sky Can't Save

Please, my Pokemon Mystery Dungeon Explorers of Sky rom can't save. Is there any way to fix this? I'm using NO$GBA 2.6a

It seems that 2.6a has problems with this game's savetype.Use DeSmuMe for this one.

I do not use DeSmuMe, it is to slow.

Well, that's that then. You can't do anything.

Well, can you at least tell me if there is a way to speed up DeSmuMe

Im using DeSmuMe is not that slow though but i cant save this game i have the lastest version.

where did you download your DeSmuMe anyway???pls??
