 the problem seems to come from decrypt_kf10thep () which needs all the available memory in the system, producing the crash

 The crash is due to the fact that NEO_BIOS_AUDIO_128K entry in the rom map is commented out.

 from johnboy:

In neodrvr.c goto line 6748 and replace 

ROM_REGION( 0x200000, "audio", 0 ) 

with this 

ROM_REGION( 0x200000, "audiocrypt", 0 ) 

Goto line 6753 and uncomment this 

//NEO_BIOS_AUDIO_128K( "5008-m1.rom", CRC(5a47d9ad) SHA1(0197737934653acc6c97221660d789e9914f3578) ) 

to 

NEO_BIOS_AUDIO_128K( "5008-m1.rom", CRC(5a47d9ad) SHA1(0197737934653acc6c97221660d789e9914f3578) )
