Sorry My speed is dial up,its sucks.I work on my hack while I wait for each page.lol.
I uploaded a new pic to my sig, try that one,if it doesn't work just try this step by step
1.Save the pic of Oak and open it in Paint etc.
2.Open it a bit so that you have a white area.
3.Paste from the pic you want and put in the white area
4.Cover the pic of Oak with Black and strech the pic of the Wattson to the size of the Oak,
and place it in the black area.
5.Now paste from the oringal pic of oak and put that in the white area.
6.Now open the rom and go to the opening and pause at Oak.This is so you can see what shades of grey will come out as what colours.
7.Use the tool that copys the colour and then use the tool that fills in a area with that colour
eg.For his hair, copy the brightest area of white,(this were you may use step 6 to tell what part is the right grey shade), and then fill in the area that you want, in this case his hair.
8.When you think you're done, write to the rom then open the Oak bit and see how it came out, any pixels that are not the right colours, change those so that are right.
9. Repeat the last two steps until you get it right
Best I could describe it,good luck
