    Not so long ago, I got my hands on this :


    From the guy I got it from, it's likely a version lent to Joypad (a french video game magazine) for their previews.

    I took it apart, and the back of the cart have some hand cutted traces, there's some awful soldering blobs on some places, while most of them others are nicely done :D.

    The chips are apparently placed in some sort of independent sockets (one by leg for all 4 chips), and there's a little 74HC139 for address demultiplexing / eprom chip selection I guess.

    I already have a chinese EPROM reader, and I also bought a little "chip lifter" thingy, but it seems quite stuck in the sockets, and I don't want to force as the last thing I want is one half of a ceramic chip :). Desoldering might be also out of the question.
    I'm thinking of ordering a Retrode when they get back on stock to dump that and check if it's any different from the commercial release.
    I think I could also do some wizardry and dump it with the MegaCD with the little tools available on retrodev.

    But I'm wondering I this will be enough to dump the cart correctly and all four EPROM entirely. Is there anything I should be worried, or make sure about before attempting this ?
    What about the cut traces (I'll try to map the circuit to be 100% sure everything is fine, and maybe resolder the ugly-looking blobs...).

    I'm not a real techie, but assuming it's the cartridge as-is after Joypad received it, I don't think you need to worry that it wouldn't function normally. The chips definitely appear to stuck in there and I'd generally avoid soldering them out since a cartridge reader like a Retrode would work just fine. I prefer taking as few risks as possible with this stuff.

    If you want to send to someone with a Retrode I got one on hand :) But if you have the tools to get that Mega CD dumper working I bet that would work just fine.

    I was under the impression that Retrodes weren't being made anymore...

    If you're afraid of desoldering, as a last resort you could always solder wires directly from the socket (on the back of the PCB) to your rom dumper.

    I had an inkling it might be the final. Appreciate your efforts though :)
