I have a doubt about Twilight Menu++

[Dizmo1]

When I started a game by the first time, then every time I turn on DS, the same game I payed before started to run. But I need to play other games, but I don't know how.

Press and hold "B" while starting TWiLight Menu++ until you see the menu. Then you can disable the autostart of the last ROM in the options.

That wouldn't fix it.

That's been removed from the settings menu years ago, and can only be changed by editing "settings.ini".
What's happening here, is some weird issue related to the SD card.

Delete "softResetParams.bin" in "sd:/_nds/nds-bootstrap/", then follow this guide to reformat the SD card: https://dsi.cfw.guide/sd-card-setup.html
