After invoking malloc 6 times, it returns NULL... Is this right? Is there any way to increase this limit?

Insufficient information for a meaningful response.

How much memory are you trying to allocate and how big is your nds file?

I have a 500k or less NDS file and I'm trying to alloc a lot of small chunks (~50b). I can allocate one large chunk (like 100kb) without problems.
