how difficult is it to port a homebrew to the 3.xx kernal? I know you need the source code, but that's all. could some one with minimal coding knowledge do it?

Depends on what it is and what functions it uses. There are 3.xx kernel equivalents for quite a few now

well, I was thinking ExultPSP. it could use the extra RAM the slim has, but I dunno if it specifically needs the 1.50 kernel.

as long as it doesn't require kernel it's quite simple, if it does have kernel, your ganna have to find user callbacks that can access that part of the kernel or if it's something small remove it from the program

you can use Slim's extra ram but I don't remember how.
I read a post a while ago on ps2dev about it

PSP_LARGE_MEMORY = 1 in the Makefile.

PSP_HEAP_SIZE_KB(-1024) or similar in your code.

does not the PSP_HEAP_SIZE_KB with a negative number means how much memory is left for the psp?

It will allocate everything but the specified negative number as heap, so you can use malloc() or whatever for it.

The reason to leave 1024 is for stuff like thread creation, space for loading modules etc.
