I'm helping a friend of mine setup his M72 Multi. It's a V2 version of the multi.
Would it be possible to post the JED file for V2 IC13 again (MULTI_M72_V2_GAL16V8.zip) ? The existing link is broken.
I would recommend buying a decent programmer for the 27c322 chips. You need something which can supply enough programming voltage. Buy a Batego, Elnec, Dataman or Xeltek.
Really like the new version, I was comparing it to my first version (2011) and it has come a long way.
I discovered some anomalies in the manual, will update you later.
It looks like your JVS IO is not connected.

To me that means that the original...
Thank you for looking into this @twistedsymphony. Is there a memory map in MAME which includes the SEI252 address space ? Or maybe this area is mirrored ? Alternately we are looking for a test which checks a value and explicitly uploads/copies data. @kold666 do you remember if the entire hiscore...
One option might be that the battery saves a config word which tells the main game to save hiscores. This means that one should run the MAME debugger, get a hi-score and see what the code attempts to do.
@Mitsurugi-w , I looked into the Flashcat XPORT and MACH at:

On their adapter page they state:
We offer a large selection of socket adapters for various memory packages and types. All of the sockets on this page are the newer 56-pin version that is...
Is your cabinet English or Japanese @Usukane ? I have made a special HDD image which does not require the dongle aimed at original cabinet owners. PM me for details.
