Not so long ago, I got my hands on this : [GALLERY=media, 2502]IMG_03022018_015809 by KailoKyra posted Feb 13, 2018 at 11:06 PM[/GALLERY][GALLERY=media, 2500]1511896122-wx-camera-1511565525866 by KailoKyra posted Feb 13, 2018 at 11:06 PM[/GALLERY][GALLERY=media, 2501]IMG_03022018_015759 by KailoKyra posted Feb 13, 2018 at 11:06 PM[/GALLERY] 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 . 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...).
