Exterior replaced. Socket installed. The original exterior had dog bite marks, and the previous owner reattached it after a failed soldering attempt. This is a cleaned-up junk item, so please purchase with the understanding that it is a used item. I apologize that the photos are difficult to see, but the exterior shines. It shines, so it makes me happy. After purchase, I will definitely replace the battery & inspect it before shipping. ☑️ Battery replaced ☑️ All Navis unlocked ☑️ Chips included as a service ☑️ Terminal cleaned ☑️ Communicated once Game Boy Advance Rockman EXE 4.5. Rockman EXE 4.5 Real Operation ☑️ I have the environment to unlock all Navis myself, so all Navis are open. Starting from the beginning will erase the data, so please continue from where you left off. You can change your name by plugging in and talking to the Navi on the left. Other than confirming the startup and talking to Rockman, it's untouched. ☑️ Operation confirmed. I played for about 10 minutes to make sure it wasn't broken. ☑️ Battery replaced. You can easily replace it yourself next time. (I don't like selling with hidden risks, so please take a look at the following if you need it) It has also been cleaned, so the reading is good. ☑️ Communicated I've communicated once because there should have been a line that only appears after a battle. I apologize for the high price, but the market price for data-filled copies is around this, and I spent a crazy amount of money to get the external equipment, so I hope you'll understand. ☑️ Chips unlocked as a service Please let me know after purchase if you don't need them. ☑️ The price fluctuates with the market price of the software. I was buying them for around 1800 yen at used game stores, but recently it's around 1200 yen to 900 yen, so I've lowered the price accordingly. It's rumored that the data will be lost if you remove the battery, but that's not a problem with 4.5. The data is saved in memory, and the clock is what interferes. If it's off, the clock will reset. Regarding the risk of short circuits during interference, it's originally installed with FRAM and 1616 is used, so the probability is low. Personally, I feel that all of them have the same level of risk (the socket is + the claws are weak). There is no certainty because there is a risk when replacing the battery next time, regardless of the replacement method. Tabs, sockets, and brute force all have the possibility of disappearing.
