Hello everyone!

I recently found a R4i-SDHC V2.10T flashcard from "www.r4sdhc.com". I know this is probably a clone of a clone of a clone... and maybe one of the crappiest flashcards ever, but as I already have it, I would like to get as much as I can from it.

Currently, I managed to install YSMenu 7.06, using the "R4i-SDHC YSMenu" folder, along with a "_DS_MENU.DAT" file taken from the original "R4iMenu" downloaded from "www.r4sdhc.com" trough Internet Archive. This is a very weird flashcard that behaves as a TTDS clone as long as the mentioned "_DS_MENU.DAT" file is present on the SD card. If this file is not present, it just displays two white screens. When this file is present, it looks for a "R4.DAT" file to load, and if this file doesn't exist, it displays the typical "MENU?" icon.

In this state, it is working flawlessly, just like any other YSMenu card, but only in my DS Lites. On my DSi and 3DS the cart is detected as "Chronicles of Narnia Caspian Prince", but upon launch it only displays two white screens (like on the DS Lite when there is no SD card, or no "_DS_MENU.DAT" file). The weird thing is that on DS Lite, the cart autoboots from the Health & Safety screen directly, without passing trough the DS menu. It seems like the flashcard uses a different bootstrap code if it detects a DS or a DSi/3DS somehow.

Anyway, I perfectly know that this flashcard is totally useless nowadays, having CFWs and TWiLightMenu, but it would be cool if at least I can get it to boot on my DSi.

Digging on the "www.r4sdhc.com" site trough Internet Archive, I found references to the following firmwares (not kernels), for this card:
  • down2.20.zip
  • down2.30.rar
  • down2.40.rar
  • down2.50.rar
  • ndsi_v1.4.3_upgrade_a.rar
  • ndsi_v1.4.4_upgrade_a.rar
  • ndsi_v1.4.5_upgrade_a.rar
  • ndsi_v1.4.6_upgrade_a.rar
Unluckily, all of this files are unavailable on Internet Archive, except "ndsi_v1.4.4_upgrade_a.rar" and "down2.40.rar", which are indeed the same (hashes compared). I installed it but the card still behaves the same ("Caspian Prince" on DSi and autoboot on DS). As I understand it, this firmware updates used to change the faked game, so I assume this is the same firmware it already had.

I tried to find any of the other firmware files to see if there is any change, but I was unable to. There are very few references on the Internet, and all of them are down.

So I come here to ask if anyone have a bit more of information on this flashcard, or have a copy of any of the firmware update files so I can try them.

The card was advertised as DSi compatible, so I assume it worked at some point. All my DSi and 3DS consoles are modded, so is not a blacklist problem, they only display a white screen, not the typical "There is an error please power down the system" message.

Yes they work, but as I explained on the first post, only on DS Lite. On DSi and 3DS it only display two white screens, no matter what kernel I use, so I suspect is a firmware issue.

Appears to be similar to a DEMON cart? TWiLight Menu++ and YSMenu should work just as well.

YSmenu instructions: https://files.deletecat.com/flashcard-archive//r4sdhc.com/readme.txt
TWL++ instructions: https://wiki.ds-homebrew.com/twilightmenu/installing-flashcard
OP is looking for the firmware that's installed on the card, not for a menu for the SD card.
The manufacturer is listed on linfox but it only seems to have backups of the menu files, not the firmware :/ https://www.linfoxdomain.com/nintendo/ds/
Maybe there is a menu archive with an included firmware update?
