No disassembly, body only. Please be sure to check the version information. This is a used item. Used item!! Please refrain from purchasing if you are sensitive to imperfections or seek perfection. By purchasing, you are considered to have agreed to these terms. No refunds will be given under any circumstances. Please purchase at your own risk. I purchased this as a junk item, but it was in working condition. Operation has been confirmed. Buttons, sticks, and UMD all work well. I haven't disassembled it as there's nothing to fix. Please see the photos for the condition. It's a 3001, so it's a Nordic version, but the circle button is set as the confirm button and the X button as the cancel button, just like the Japanese version, so you can use it without any problems. (I can revert it to the original settings if you wish) I applied oil because of a strange noise when reading UMDs. The noise is gone now. There might be a smell of oil. ※UMDs also work well, but in rare cases, it may not read certain software. Body only
