Thank you for doing that and taking the pics..
Yes..yes very much as I just listed my Metal Slug 3 MVS cart on ebay yesterday and it has the daughter board...(Uh Oh,I thought upon listing it as I'm going to be asked about what the heck is it..
Do you know what it's for,why was it used in these games as I then can save me some headache time trying to explain this when asked..
Thank you.

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.

Hi,
http://mvs.gotwalls.com/index.php/Metal_Slug_3
i have a set 1
is there any difference with this sub daughter board?
btw any diff between Metal Slug 1st & 2nd run?
Thanks in advance

Here is what my MVS MS3 looks like (on the right) compared to my AES Samuari Shodown 2 that I want to convert to. The case of my SS2 was junked so this hopefully will make a good conversion. Once I get permission to start a thread I'm gonna post some questions.

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.

Yup, exactly. Whenever you do conversions always make sure the donor board can actually support the chip and has proper chip types.

From what I can tell in the pictures, the daughter board has 64mbit of flash memory (4 16mbit chips). The NGPC programming hardware would only have been able to address half (2 of these 4) chips. To program this board, a developer would plug it in to the programmer, program 2 of the chips, turn the board over and replug it, and program the other 2 chips. Notice that there is an edge connector on both sides (where a normal NGPC PCB would only have fingers on one side).
So, yeah, I can only imagine that they used this as a simple way to modify the "ROM" contents (for debugging/upgrading/etc.). I would think there'd be other easy ways to write the flash chips, but maybe they wanted to piggyback on this system for some reason.
It's also worth noting that, at least in the NGPC case, the system itself could write to the flash chips. Is there any possibility that the MS3 cart would store data on the flash chips?

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?

Don't mean to resurrect a dead thread- but should all MS3's have daughterboards or just the early ones? Here is mine (SN > 40000)

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.

Yes, the order I described the cart sets in is probably how they were released. I also have a MVS Metal Slug 3 with PROGBK1, it has a high serial. It most likely was made after SNK Corp's closure.
Any of the Metal Slug 3 sets are suitable for converting. If you have one with PROGBLA, just get KOF 99 or 2000. If you have PROGBK1, get a KOF 2001. To stay authentic, the former should have JP artwork and the latter should be English.

Again, not making a conversion. Just curious. And thank you for the info about MS3

Football frenzy is such a terrible game. Anyway- no worries. I don't have an AES and I am not making a conversion- I have a NG CD, an Omega CMVS, and another CMVS which I bought from JNX that is stuck in transit.

Ok, then we're cool. Curiosity is fine. But if I ever catch you with a conversion, ....
I totally get that
