Homebrew Can't play Cartridge games on my 3DS

[Edwinsalnd]

Hello, whenever I try to launch a game on a cartridge like Mario Kart DS and Paper Mario on my OLD 3DSLL, an error would always appear . This problem started occurring after I formatted my system with CFW. (I followed a guide on youtube ) (I'm also on Luma 10.2.1 version). Before doing a system format my 3DS worked fine with cartridge games but now error I can't even launch it. This message also appears when I select the "Nintendo DS" option on the download play app, but this problem does not occur when I'm launching installed CIAs. Can somebody help me how to fix this?

I can't upload the image of the error so i'm just gonna type it.

An error occured (ErrDisp)

Follow video guides isn't a good idea. And format the console isn't necessary (only in a really few of cases is mandatory).

It seems to be a problem with the DS mode functionality. Try then with this solution.
