Let me start off by saying that I'm new here. I've been poking around the internet looking into these flash cartridges, and I found this to be one of the most active forums, so I thought this might be a good place to ask some of these questions. Short version: I was wondering if anyone could help me find references that would indicate what the R4i-SDHC is a clone of, and if it can be upgraded to work with the DSi 1.4 firmware. I had heard rumors that when the original R4 team broke, different members went into business for themselves. Is this true, false, or one of those "the world may never know" things. Long version: These questions pertain to the R4i-SDHC, (r4i-sdhc.com) which comes in a red box. I am quite well aware that the original R4 team is no more, and that the R4i-SDHC is one of many cards trading on what used to be their good name. I don't need to see the word "fake", and I don't need any recommendations for cards with longer-standing reputations at this time. First off, I have noticed a number of people stating that the R4i-SDHC cannot be updated to work with the latest DSi firmware (1.4), as the only updates available are for the kernel, whereas the bootloader cannot be changed. These people often cite the fact that the R4i-SDHC is a DSTTi clone (which, apparently, also cannot have it's bootloader upgraded). I was wondering if anyone could help me find references for these statements; I've tried searching, but all I come up with are posts with the same conjecture. Naturally the R4i-SDHC website isn't going to advertise the fact that they are a clone of anything, but I was wondering if there where some in-depth article or review investigating the origin and capabilities of the R4i-SDHC. There doesn't seem to be an official review from GBAtemp (I can't really blame anyone for not reviewing every card that gets put on the market) or from really any other site. What I do know is that the R4i-SDHC website indicates that they are aware of this firmware issue, and that they are working on a solution. What their solution will be is a currently a matter of speculation. It could be a new card, like the "R4i Gold" that was released, or it could be some manner of firmware upgrade that would be inconsistent with some of the conjecture mentioned above. Or the solution might be to set up auto-replies to email inquiries indicating that they are hard at work, axe their development team, and try to sell the remaining stock of cards to DS, DSL, and DSi 1.3 owners. Personally, I'd be inclined to give them another month or so before deferring to the "dried up like so many others" theory, but as far as the upgrade capability, that goes back to what the hardware is based off of. I have also heard rumor that when the original R4 team broke up, some or all of them went into business for themselves making their own versions. My first impression would be that this was someone's guess as to why there were so many cards trading on the name R4, including versions that aren't awash in complaints of ROM incompatibilities. Does anyone know if there is any truth to the rumors?
