Is this a Gameboy proto?

[GKnight]

This is the GBC game Rampart. It came in a strange case & has dip switches on it though I don't see any eproms on the circuit board. The case is slightly bigger than normal GB cases and you almost have to force it into the console, which makes me think it's a pirate or something, though the game seems to work fine and the circuit board has "Nintendo" printed on it.

Anybody know if this is a proto?

Thanks.

Yes, it is. Nice find

What exactly does the dip-switch do one this cart?

I'm not sure what the dip switches do exactly. I've played around with them a little but still can't tell what they're for.

To me it appears to be a generic prototype board. It clearly has a 2Mbyte NOR flash chip for storing the game, which implies that there was a fixture for reprogramming it. And it has a Nintendo part number DMG-B02-01, so it's probably an official Nintendo generic prototype board.

 

The switches would be to set various mapper options such as game size and whether or not to enable the battery backup RAM.

 

The chip on the lower right says "1M SRAM", so it is 128K bytes of battery backed SRAM.

 

The 8-pin chip in the middle is the battery regulator chip.

Thanks, that is very informative.

Lol, hope not.

From my old Gameboy developer days, I wanna' say that I recall that being the way you set the cart to be NTSC or Pal.

 

It's been awhile though.

Gameboy PAL or NTSC? What for?

 

That would seem strange for somthing that doesn't hook up to a TV.

... though the game seems to work fine...

What game?

Except the Game Boy is region free...

cool find ive never seen a gameboy prototype before

So if you put an overseas gameboy cart into a Supergameboy it will play just as the US cart on an NTSC TV?

Never tried it, but it should work fine since the NTSC/PAL signal is produced by the Super Game Boy itself, not the Game Boy cartridge.

 

Game Boy screens did not come in NTSC and PAL varieties...they all have the same resolution. So there's no reason why NTSC and PAL display modes would've been programmed into the original games.
