Thank you for viewing! This is a Game Boy Advance (GBA) unit featuring: * Black Clear exterior * Yellow buttons * IPS LCD The exterior shell has been replaced with a custom black clear (smoke-tinted) shell. The design allows a subtle view of the internal components, creating a custom look with a calm atmosphere. The button colors are yellow. It is equipped with a high-quality IPS LCD, significantly improving brightness, color, and visibility compared to the original LCD. The screen is high-definition, allowing for comfortable gameplay both indoors and outdoors. It supports 1-8 level brightness adjustment, and you can adjust the brightness with a short press. It also supports display mode switching (long press), allowing you to switch between multiple display modes, including HD mode, SL2 mode (scanline-style display), PIXEL mode (retro display that reproduces the dot feel), and black and white display. The photos posted show examples of each display mode on the actual unit. Due to the custom nature of the exterior, there may be slight dust particles or minor misalignments in the shell during the manufacturing process. Please refrain from purchasing if you are looking for a perfect condition. Before listing, I have confirmed all basic operations, including game startup, audio output, button operations, and LCD display. I will ship it in working condition. This product is a custom item based on a used unit. The exterior and LCD are not original specifications. I cannot guarantee the operation due to the batteries used, game software, or the usage environment. Returns and refunds are not accepted, so please purchase after understanding the contents. If you have any questions, please feel free to comment.
