I recently changed my firmware with a new one but for some reason lictochat doesn't work I mean I can enter it I can even quit but when choosing the rooms nothing happens when I click on them it shows that I clicked on it by making the icon darker but still doesn't join I would really appreciate someone helping especially when this is my first time using melonds and have the experience of a ds

This might be a niche question but I kinda want to start from the beginning like with no already installed name and favorite color and stuff even if I can change them so I've spend like half this day trying to find how but didn't find one so I thought reddit might help me I'd really appreciate any help from u and bye
