Re: Is there some way to dump a Mega Drive Multicartridge

The two non-epoxy blobs say "MC74F174N" and "SN74LS32N", correct? If so, I'm using this reference: http://wiki.megadrive.org/index.php?title=Connectors Reads or writes to $A13000-$A130FF latch A1 through A5 The latch is cleared on reset. The values latched from A1 through A4 are ORed with A17 throu...

Is there some way to dump a Mega Drive Multicartridge

I have a Mega Drive Multicartridge that contains 40 Games and I wonder if there is some way to dump it (other than Retrode).

Re: Problem while switching on genesis

If you have a multimeter / continuity meter: 1) While the genesis is off, make sure A and B are not connected 2) While the genesis is off, see if pressing the button makes A and B connect 3) If both or neither: the problem is somewhere else 4) If only either one: the button is damaged. 4a) If only ...

Re: Problem while switching on genesis

I told the seller to bring me Genesis Adapter , he brings me a weak one :( Go home seller u're drunk :lol: The seller sold you an adapter that can power a real Genesis 2 (my Genesis 2 is rated at 10V, 850mA) but not your clone. Since your clone system looks a lot like a Genesis 1, you probably need...

Re: Problem while switching on genesis

That should be enough voltage. Other people claim you need more current (but I don't know). Do you have a multimeter? If so, make sure that when you're playing, you see at least 7V going into the connector where you plugged the adapter into the Genesis. no they're right cause I read the details on ...

Re: Problem while switching on genesis

And what you experience is definitely too weak power supply. You need at least 1A (the more the merrier) and more than 7V (but less than 18V). but as u see what I described above..the adapter is 10V namely more than 7V , so how is it too weak? and where "1A" is written on the adapter? 1.0 A = 1000 ...

Re: Problem while switching on genesis

Yes, it's a clone. A real Mega Drive/Genesis would have the Sega logo silkscreened on the PCB and a few of the ICs. I've found some pictures here if you'd like to compare your clone to real Mega Drive hardware. no there is a difference between them in form :twisted: :lol: Because it's broken no I m...

Re: Problem while switching on genesis

That thing is 100% definitely a clone, but what is called a superclone that uses exact copies of the original chips (same pinout too !). And what you experience is definitely too weak power supply. You need at least 1A (the more the merrier) and more than 7V (but less than 18V). but as u see what I...
