Need some help compiling MacMAME

[Bakasama]

Since this board seems to have a fair number of programmers, I thought I would get some help with this.

 

I'm trying adapt some of the code from Misfit MAME 122 to MacMAME 103a. After many hours of work I managed to get MacMAME to compile without errors with added code. One of things I'm trying to do is making MacMAME work with this. It's a hack that saves high scores from Crazy Kong into NVRAM. I managed to get MacMAME to load the game but I've hit a snag. The app crashed due to:

 

"MacMAME has encounter a problem"

"nvram handler called without nvram in the memory map"

 

Me being not so great with C++, I found out what the problem is but I don't know how to fix it.

 

Here's the code that's stumping me:

 

static MACHINE_DRIVER_START( ckong )
MDRV_IMPORT_FROM(cclimber)
MDRV_VISIBLE_AREA(0*8, 32*8-1, 2*8, 32*8-1)
MACHINE_DRIVER_END

static MACHINE_DRIVER_START( ckonghs )
/* basic machine hardware */
MDRV_IMPORT_FROM(ckong)
MDRV_CPU_MODIFY("main")
MDRV_CPU_PROGRAM_MAP(ckonghs_map,0)
MDRV_NVRAM_HANDLER(generic_0fill) //problem code here
MACHINE_DRIVER_END

 

If anyone can tell me what I did wrong and help fix this, I would grateful.
