3DS Console and Complete Set - Junk Condition

I briefly checked the main unit, and it works without any major issues. The buttons function properly. It does charge, but I haven't tested how long the battery lasts. The battery seems to be slightly swollen. It works fine if the power cable is connected normally, but sometimes it stops charging momentarily if the cable is moved. I suspect the charging cable might be faulty, but it could also be the main unit. I confirmed that all the software boots up, but some errors occurred. I was able to get them to start by reinstalling them. Since it's an old item, you might need to reinsert the software cartridges a few times. Some software didn't appear, and I had to use my finger to get them to load. The box has scratches and stains. Please check the images. This is an old item, and I've only checked it for a short time, so it's being sold as junk. Please only purchase if you understand this.
