Hi , i have found my old nintendo dslite . I have also old r4 , so i downloaded BL2CK version and many games.
When i try to play , for example,pokemon platino a white screen appear . Why? I download wrong games file?
Because i have also original games of diamond pokemon and it work fluently . So i think the problem is the file games or probably the firmware.
Thank you for helping
Yes, very likely you've got a bad rom. Replace it and see if that fixes your problem.
On the matter of your card: Firmware = Kernel
Updating your card's Kernel is recommended as they provides patches for antipiracy and improves game compatibility.
Question is: Is your Kernel still available nowadays?
R4s are quite old and most are clones of clones, so finding the appropriate Kernel is a pain in the ass.
First make sure you make a backup of your current Flashcard's files before attempting to "update it".
Once you've made your backup, go to your Flashcard's website and check for the latest Kernel version. If available, download it and try to see of that fixes your problem.
If you can't find the original website for your Kernel, try using Wood, YSMenu or another "third party" Kernel for R4 clones.
Lastly, check this website and see if your card is listed. They host original Kernels in many versions/updates and you can trust this site, I've been using it since 2009:

Use a 10 minute mail as downloads are for members only.
Alternatively, there's Rocketrobz' Custom Firmware, so that's something you can try as a last resort.
