Differences between genuine SD2SNES and Chinese clones
« on: July 10, 2016, 07:17 PM »
Hi guys.

As most of you, I'm planning to buy a flashcart for snes and I want to  buy the best one possible. I think everyone agrees that this one is the best option. But here where I live it's hard to import items and I have to buy from local vendors who import themselves. The thing is there is a lot of Chinese clones out there and people keeps saying that Chinese clones are bad and can even brick when updated. The other problem is that I have no idea on how to identify genuine board. Some says that the deer painted on the pcb is the only thing that can differ the original and the Chinese ones. Please help me avoid trouble with the Chinese! (With pics if possible).

Some capacitors/resistors appear to be different. I have a Chinese version and it works flawlessly. No problems updating firmware.


edit: here's the results from the diagnostics test from sd2snes.de

I also have a chinese SD2SNES and it works flawlessly as well.

Theoretically, there should be no reason why the chinese SD2SNES should be out-of-spec, as all files necessary to build an SD2SNES unit are on ikari's GitHub. If you have the tools and the knowledge you could build one yourself.

But this is China we're speaking of, the pinnacle of shoddy QC/QA, so in the end YMMV.

ikari once said that he was even asked by a chinese distributor if he can make his own. ikari just said that he won't give support for these, never that the firmware does not support em if they behave nicely. So updating of a good "clone" is nice and can be done.

I have both an "official" one and just bought a Chinese one.  The Chinese one doesn't work with MSU audio games (just before the 4 min mark):  https://youtu.be/5i1XsTtCerM

that's very strange. have you measured the SD card access times?

Where are you located? If the resellers can import it you can do it too.

If the only option is buying local chinese quality products then test the cartridge before buying running the "diagnostics firmware".

Same exact SD card I use in my real SD2SNES. Good thought though.

A quick trip to Google reveals:

QC/QA
YMMV (includes definition)

TL;DGI (Too Long; Didn't Google It) China is known for some poor quality control checks and assurance for most, if not all, products. So, in the end, if you get a "China Version" of an Everdrive or SD2SNES in this case, you might get one that works perfectly or you might get one that has one part soldered on incorrectly. Hence, "Your Mileage May Vary".

There's a DAC, to the left of the SuperCIC (the PIC 12F629 microcontroller) maybe there's some bad soldering around that area. If you want I can try to help you fix it, just PM me

I lent it to a friend to use until his real SD2SNES comes in the mail.  I'll check it when I get it back.  Thanks for the offer!

I believe TL;DGI stands for too LAZY; didn't google it ;)
