The GWGBA is an adapter which allows the user to attach a Sony PSOne 5" LCD screen(not included in the auction) to a Game Boy Advance(also not included) outfitted with a modified GBA Transverter thus providing a bright and very high quality video experience through the use of an RGB video connection. It's display quality is superior to the newly released Nintendo Gameboy Advance SP because the PSOne screen is backlit and is larger than the GBA SP screen which is just a front lit GBA screen. Small text and fine graphics detail can now be easily seen without being overly pixelated. Play in dark or badly-lit areas. This is the best way to play GBA. It also outputs stereo sound and can mirror the output on a TV. The GBA image can be stretched to fill the entire screen or can function in the normal, unzoomed mode. It provides better quality than my previous creation, the MiracleRay, mainly because it stretches the image to the edges of the screen. The PSOne LCD is easily secured to the GWGBA, so the LCD screen doesn't have to be modified. The image quality is nothing short of amazing.
