it´s a mvs subboard based on ngp knowhow. It enables SNK to program/reprogram the P roms with snk´s ngp cart programmer.
In case there is a big glitch that passed on beta testing, this enables SNK to service the 1st batch run of carts with ease.
I think SNK also rolled carts into production while debugging the game and then added the P roms by hand on the 1st MVS run.

I'll give you the first and final answer for your conversion project:
It's never going to work!
MS3 has encrypted roms, it needs donor boards with decryption chips.
You will need a kof99 homecart to pull this one off.
Its weird to see this I had a MS3 just like that but I sold it years back because the contacts were a little worn.Have you ever wondered what was on the other side of the NGPC looking board?
There are three distinct sets for Metal Slug 3, they all use the same CHAFIO board. Set 1 uses PROGBLA and the NGP dev board for the P ROMs. Set 2 uses PROGBLA and regular mask ROMs. Set 3 downgrades to the unencrypted PROGBK1.
Very interesting. Mine (set 3) looks like it was distributed right around the bankruptcy, is that why they switched? I guess set 3 would be the best choice for an AES conversion...
Looks very similar to my MS4 cart.
wait a sec., why are you guys helping people to make conversions? DON'T DO IT BRO! Leave that cart be and get a converter, a CMVS or a legit home release. It is a shame to butcher carts that work on their own. Come on.

Sorry, it's a reflex. So many people have helped me with tech stuff, I feel compelled to do the same for others.
It's good to have knowledge, although I wouldn't make a Slug 3 conversion since none of the games you would use as donors are terrible common carts. I'd happily sacrifice Football Frenzy or something if that were the donor.
Ok, then we're cool. Curiosity is fine. But if I ever catch you with a conversion, ....I am not making a conversion. Just was curious.
I totally get thatSorry, it's a reflex. So many people have helped me with tech stuff, I feel compelled to do the same for others.
