My card looks pretty much the same as the ones posted by OP, and (also ChipID 000007C2, HW Rev FFFFFFFF), though I'm noticing that mine and the other posters have slightly different markings on the cards. Images (Click to Expand) (sorry the photos are really bad, I only have my laptop's camera to take photos) There's a number near the contacts (3 in my, OP, and (possibly) mariogamer's case, and 2 on lavanoid's card). There also seems to be some kind of revision marking in the corner: 's seems to be B5-V1.1, mine is B6-V2.7, and 's is B6-V2.5 V12, though I'm unsure of the purpose. Hopefully this is somewhat useful.

Those markings are in what's called the silkscreen layer. Just like with a shirt with a logo on it, paint is silkscreened on to pcb's towards the end of the process, before the components are placed on to the chip but after the soldermask etc are done. These markings do indicate some kind of revision, but I have no idea if the revision is in base firmware or if theres a different chip under that epoxy. With cheap chips like this, theres a chance that they didn't use proper electronics-grade epoxy. Is there any chance you have any acetone (nail polish remover) in your house? If not, you can buy 100% pure acetone at your usual drugstore.

Sep 05, 2013 Buy r4i sdhc card from: 1. Go official website and download the latest R4 SDHC kernel to the compueter. Instruction of Kernel Installation & Firmware Upgrade for R4 Gold Pro, R4i GOLD PLUS & Wood R4i Gold 3DS.

Dabbing some on there with a cotton swab would remove some of that black blob if it's not real epoxy, potentially revealing a stencilled chip ID on the back of the integrated circuit under there. It's a shot in the dark but if one of you have a chance it might be worth a shot. And to be clear: This is not a 'R4i Gold RTS Wi-Fi' (like said in its one of these cards: My reqeust is to call the Cards by url + printed name. Like for me (), i would write it down like 'r4i-sdhc.com R4i 3DS'.

I wouldn't put the Wifi here cause its every time there for each model. For the different versions 'r4i-sdhc.com R4i 3DS V.4.5' or 'r4i-sdhc.com R4i 3DS RTS'. My r4idsn i would write down r4idsn cause its the only card from them and not 'R4 New 3DS Revolution for DS'. When we talking about revision numbers we can put (x) at the end. C5emu Fix.exe more. This 'flash.r4i' can be hex-edited you know? By looking at the hexadecimal structure of it, we actually have the way on how the R4i 3DS card speaks to the flash chip.

Bangla Science Books Pdf. The card actually spoke via WifiEngine to ask for a upgrade. If it has got one, WiFiEngine collects the flash.r4i from the r4i-sdhc.com server.

When it is finished, it is stocked into R4iMenu. After that, the R4i chip could be updatable.

But for some cases it actually changed the emulated game, which can also change read/write structure (ico the update is bigger than the last version). EDIT: There is the latest flash.r4i available from September (edited derp) 2016 (yes it is still updated xD): EDIT2: Methinks I've did a browser exploit PoC, attempting to click on my website with this r4i file results in a loading loop xD.

A combination of methods was used to support these carts. Angelsl started out by using a spi flasher and a logic analyzer to figure out how it reads from flash. During this process, they figured out that it wrapped communication to the flashchip directly, instead of abstracting it.
