broadly used. Added memory interface to the intelfsh device so you can access/view the data in the debugger and via the standard memory interfaces. Removed the old memory() method in favor of new functions read_raw()/write_raw() which do direct reads/writes of the data. Cleaned up CPS3 No-CD sets to break up the "ROMs" into individual flash pieces which are automatically loaded by the intelfsh device on initialization. Also split the MACHINE_CONFIG to only populate the number of SIMMs actually present for each game, as documented in the top of the file. And replaced the NVRAM_HANDLER with an NVRAM device.
