The GP32 BLU (standing for Back Lit Unit) was another iteration of the GP32 (the equivalent of the brighter GBA SP), again having nothing changed in appearance, except for a now back lit screen, much better than the FLU. The BLU gave players a very bright and colorful screen. This unit was introduced in 2004, and later that year they even released it in Italy, France, United Kingdom, and Spain.
