[A83] Re: Help! I can't display my title sprite using bcall(ionputsprite)!
I suggest checking out Matt Johnson's Image Studio, or Rusty and Corey's
Graphics Studio (free version for calcs available). It will dither a
picture for you, and convert it into a format that the calc can use. Image
Studio will output in RLE format, which will save a lot of space is there
are repeated horizontal areas on the picture. Since most title screens have
a lot of blank space, this works quite well.
