Thank you for viewing! QQ174 This is a Game Boy Advance (GBA) custom model featuring a transparent, iridescent custom shell, purple and pink buttons, LED light-up customization, and an IPS LCD. The exterior of the unit uses a transparent, iridescent (clear) custom shell. In addition to the see-through design, the light-up feature adds to the visual appeal. The button colors are purple and pink. It is equipped with a high-quality IPS LCD, which significantly improves color, brightness, and visibility compared to the original LCD. The screen is high-definition, allowing for comfortable gameplay both indoors and outdoors. It supports 1-8 levels of 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 (dot-like retro display), and black and white display. The photos posted show examples of each display mode on the actual unit. The interior of the unit has LED light-up customization. This LED is a custom modification by the seller and illuminates the inside of the unit when the power is turned on. It does not affect gameplay itself. The light-up effect is especially striking in the dark. Due to the custom nature of the exterior, there may be slight dust particles or minor misalignments in the shell from the manufacturing process. Please refrain from purchasing if you are looking for a perfect condition. Before listing, all basic functions such as game startup, audio output, button operation, and LCD display have been checked. It will be shipped in working condition. This product is a custom item based on a used unit. The LED light-up customization and exterior/internal modifications are not original specifications. We cannot guarantee performance differences due to the batteries used, game software, or the usage environment. Returns and refunds are not accepted, so please purchase with understanding. If you have any questions, please feel free to comment.
