. Yes, my config was off centered in the past, but not now.
You can also use HighGFX 800x600 with my config following the instructions.
Listen if you are using images made for RTG they are surely using some million colors, and you only need 256 if you don't have a graphic card.
Send me the image you want to use and I will convert it to png or iff 256 colors. Anyway you only have to use a program like Image Studio.
