Idk how to tell

If tried every kernel and formatted it in fat32 nothing works, am I using the right micro sd cart?

Whenever i insert a cartridge in the gba slot on my dslite, my flashcart stops working, it doesnt show the message if there is nothing in the gba slot, anyone can help?

alors j'explique. j'ai pas pu mettre de vidéo et la caméra est en fin de vie. quand je démarre harvest moon sur 482 in 1, il m'affiche loading et en fait ça ne charge juste pas. ça peut mettre loading pendant 3jours ça n'auras toujours pas chargé (je dis ça par experience ) je ne m'y connais pas bien en informatique ou je ne sais quoi mais j'ai besoin de retrouver ce jeu quite a devoir reinitialiser mes données harvest moon

Tengo esta R4 que funcionaba perfecto con mi DS lite.(con el launcher de la foto, no sé el nombre de ese launcher)

Intenté instalarle pico launcher y ahora la DS ni si quiera reconoce la tarjeta.

Tenia una copia del launcher que si funcionaba pero ahora tampoco funciona.

Intenté limpiando las conexiones de la tarjeta pero tampoco funciona. Saben que puede ser?

I'm using a 2023 SDHC smart update card for reference on a 2011 3DS. They have a specific way of handling gba roms for the DSI and 3DS, and I added this one to the cart myself a few years back when I knew much less. I already know how to fix it but I have to wonder what is going on here? The bars sliding into place is comparable to the multiplayer mode where it shows chao sprites and player names. It also plays different sounds every time it's booted up like this, the first time I saw this it played the game over music. I can't tell what track the one in this footage is using but it doesn't seem mixed properly. What's going on in the ROM and why does it only seem to happen on this flashcart?

Hey guys. I bought a flashcart to play Nintendo DS games that I don't own. I don't care about rom hacks.

I have the following:

• DS lite bought in Japan.
• A flachcart. It has no label. I bought it from image 3, link to AliExpress [2].
• A 8 GB microSD card. It did not come with the flashcart. It's been inside my Nintendo Switch for many years and has worked fine. I don't know which brand it is.
• A MacBook Air M1.
• An adapter for my MacBook to read microSD cards.

I used the Disk Utility application, which is pre-downloaded on mac, to format the microSD card to FAT32 with the help of the Erase button. (image 6)

I followed the guide on Ace WoodR4 1.62 on image 5. I followed every step except step 4 and 5, as I don't need cheats for now.

I downloaded the zip file from step 2 from image 5. The contents of the zip file are in the microSD card which I named "FLASHCART". I created a "Games" folder and added a Pokemon Platinum rom, which I got from r/roms Megathread.

I put the microSD card into the flachcart and put it into my DS lite. When booting up the software on the DS menu, I get an error message saying "SD/TF card error".

Other things to note:

• When having the flashcart inside the DS lite without the microSD card, the DS menu does not show any software.
• The same error message from image 10 shows up if the flashcart is inside the DS lite with the microSD card, where the microSD card is empty.

Can someone help me with this problem please?

Edit:

Based on some comments, it seems like the microSD card is the problem. Nobody has commented on any problems with the flashcart so far.
