I need help with the data on my Flashcart.

Hello!I have a empty Flashcard and I tried a lot of firmwares but non of them worked.The Flashcart is this one:
I have a regular DS Lite, is quite old. If someone can help me it would be really good.

Try talking to [user=4218940]@Soundbox3[/user] (topic: https://forum.romulation.net/threads/identify-my-flashcart.64495/).

Maybe you should try the 2014R4isdhc-sliverEnglish3.01.
Make sure to put the firmware files and several nds roms on root of the microsd card.
