| *Notes: * t613 + tas5130A |
| * * Focus to light do not balance well as in win. |
| * Quality in win is not good, but its kinda better. |
| * * Fix some "extraneous bytes", most of apps will show the image anyway |
| * * Gamma table, is there, but its really doing something? |
| * * 7~8 Fps, its ok, max on win its 10. |
