Hello Fellas, I choosed to reply here instead of opening a new thread.
I have an (supposedly) R4-sdhc (NOT R4i) that is actually an TTDS Clone, I can confirm that because it asks for TTMENU.DAT if you don't install the correct firmware on the SD Card.
I can use it without problems on my O3DS thanks to the ApacheThunder's Stage2 Launcher designed for TTDS Cards,
But I cant make it boot on the DSi with HiYaCFW, NTR Launcher or SRLoader (Now called DSiMenu++), I just can't, I tried everything I could but nothing worked, do you guys know If I am doing something wrong?, on the DSi I cant get past the Loading screen from the card itself, It just gets stuck there.
Also, even tried to export the Stage2 Loader from my 3DS and import it to my DSi but that didn't work either (I think that wouldn't work anyway because it was designed for 3DS and not DSi but I had to try)
This is a Japanese DSi, I don't know If that could be the main problem, once I installed HiYaCFW I couldn't use the touchscreen anymore on the Settings screen when I boot into OFW, on the rest of the software it works fine
Thanks!
