[GBDK] Fading effect
I want to use a fading effect for the DMG GameBoy. But I want to fade the screen to white (like the pokemon red/blue intro). I found some C-code with google, but they only fade to black.

Re: [GBDK] Fading effect
The Code I tried to work with is from the gbdk examples. It's the galaxy.c. There is a function called fade().
Here is a link. You can find the function at line 388.

I also found the same document with more information about the code:

Re: [GBDK] Fading effect
Ok, i already found a solution. I changed the values for the BGP_REG. But this only works for the Background. To fade sprites you have to use the OBP0_REG.
But thank you for your fast answer cat
