Describe the issue.

I have been trying to dump my PAL Starwing cartridges for ages now, expecting it would magically work with every new firmware release. I've thoroughly cleaned the contacts and inspected the PCB, but can't find anything wrong with it.

Oh... epoxy-style ! Is this coming from a PAL cartridge ?
Various Star Wing carts I've dumped until now were all using big PCBs, and dumped fine with OSCR. I've never tested one like yours.

At least you got a rev0, confirmed by header and PCB label, so final CRC32 should be 865F1A71.

Have you tried to double clean the pins ? With a soft rubber for example. Also, using 5V ?

[BenoitCaron]

Yes the epoxy had me wondering at first, but there seems to be several revisions of Starwing, so it seems my cartridge is legit. I have cleaned the pins to the best of my ability, and I do use 5V. Again, this is the only cartridge I haven't been able to dump so far (tested every slot with every cartridge type multiple times).

Is there a way to tell what version of the PCB is inside the cartridge? Does the label differ from the normal version? It looks interesting.

[BenoitCaron]

I've posted pictures of the PCB in my first messages, all labels are visible I believe

[PsyK0p4T]

@BenoitCaron can you post some pics of the cart's front sticker ? I have the feeling that it will be pretty same for every Star Wing carts. Here is mine :

@sanni if we can't identify them by stickers, it should be possible by looking at cart's bottom side.
The PCB with big chips is brown around the pins. Whereas epoxy one looks more greenish.

Absolutely, here it is
