What can you do with GFX Tool?
First of all, you can customize the graphics settings for all of your games. This means you can play your favorite games with 60 FPS, 90 FPS, or even with the highest graphics setting, which is called Ultra. And the best thing is that you can do this for all of your games, not only for one or two games.
Secondly, you can use the GFX Tool to upload your own active.sav file, which is a kind of backup file for your game. This will allow you to load the game on your device faster than before. Thirdly, you can use the GFX Tool to set a higher resolution for your screen, which will make the gameplay even smoother and more immersive.
