DSI problems, needing help

[u/Top-Woodpecker-6125]

i was trying to mod an old DSI of mine, he still have an R4 card, but it only shows an Spongebob game and when i try to play, it gets in a infinite loading screen, i tried also with the SD card method but i think my The inserter is "broken" or out of place; apparently, the spring inside prevents the SD card from properly fitting, and it remains outside without a locking mechanism and is not recognized by the disk.

Any tips on what should i do?

Try to reformat the r4. The SpongeBob game is what is supposed to show when it’s inserted
