I recently bought this R4 SDHC "Plus" flashcart from this website: https://nds-card.com/ProShow.asp?ProID=507 since I had previously bought a different cart from there that worked fine, but I haven't been able to get it working despite trying to use multiple kernels and SD cards, it always displays "Cant open _dsmenu.dat". Is there anywhere I can find a compatible kernel or is this just a cheap clone that will never work? I included a picture of it for reference.
