You can start playing with it as soon as it arrives. I purchased it new at Yodobashi Camera in Akihabara in 2011, and it has never been in anyone else's hands since. It's a PSP-3000 version 6.39, customized to 6.39PRO-C2. Removing the battery or completely turning off the power will revert it to version 6.39, but you can easily recover to 6.39PRO-C2 with the pre-installed 639 PRO-C Fast Recovery. I will sell it to someone who understands its value. ＜Condition＞ ・Operation confirmed. All buttons respond. ・Example of pre-installed games: Patapon 3, Metal Slug 1, 2, 3, 4, 5, 6, X ・The metal part for fixing UMDs inside the UMD slot has been removed, so the UMD will not be fixed in the specified position and may not read properly. I don't think the disc reading mechanism is broken. ・Please check the screen condition in the game screen photos. ・There is a slight crack in the bottom right of the screen. ・Not disassembled. ※Please note that if you update the firmware, the currently installed software will no longer be usable. ＜Set Contents＞ ・PSP body (PSP-3000 white) ・Battery cover is black ・Genuine battery (can play for about 1 hour on a full charge) ・SONY genuine memory stick (8G capacity) ・Charging and data transfer USB cable We recommend that those who understand customized products purchase this. (We cannot provide support.) Thank you for reading to the end.
