I can't dump the PRG nor run it on my Famicom console. I just know that it is a game from Konami + Unknown 32 Pin PRG + 28 Pin 6264 CHR-RAM 8 KB. I want to know the its mapper and then find out what game is inside it.
The 6264 is 8K RAM. As for the rest, if you just want to dump it, it should be pretty easy with your eprom reader, just trace back the edge connector pin to as much pin as you can on the MASK ROM and then you can figure out the rest of the unknown pin once you have enough info. And the PRG must be 512k if we consider the silk screen inscription. With the dumping job you did before on your pirate glop top cart, I don't see that as being a challenge for you even with half of the board missing:) Only 1 chip to dump. My first guess would have been iNES mapper 2 but then again it can't be this one if it's really a 4m maskrom... But then I'm definitly no expert, the other will probably have a more knowledgeable opinion on this!
BTW, where did you get this stuff? I'm curious also to know what's on it:)
He's probably getting this stuff either in Iran, or in Turkey. Martin Nielsen (NESWorld maintainer) often visits Turkey and finds crap like this all the time.
Whatever that game is, it's not on bootgod database. I made a search for game using that chr-ram chip and only a few came up and none by konami. How do you know it's by konami BTW?
It seems that only a few traces are going up to the part that's been cut off, so I don't think the mapper on that board was very complex. If I weren't so lazy I'd check which traces have been cut to take a better guess at what mapper it was.
The board seems to claim that the PRGROM is 4mbit = 512KB? But Bootgod's DB doesn't know of any 512KB Konami games, either (other the lagrange point, and this is definitely not a VRC7 board)
Already mentioned by SkinnyV, but the 512KB of PRG-ROM is throwing us off. UNROM has 128KB, UOROM has 256KB, but I'm not aware of a compatible board using 512KB.
Game Boy Advance and Nintendo DS cart access uses a seek/read style protocol, and their custom mask ROMs have the required mapper circuitry right on the die. Likewise, if this mask ROM is UNROM compatible, it might have a 5-bit register and OR gates on the die.
Can't you figure out the size seeing which pins aren't directly attached to the bus? No pirate cart or even licensed cart did the on-die decoding, so why would that be used in some cheap pirate multicart? But anyway, looks like it's a 1 chip mapper, so it can't be hard to guess which one. Maybe dump the ROM and then look at the code and capture the $8000+ writes.
