About SP-404 MKII Startup Screens

The SP-404 MKII displays three frames during startup. While the first frame always shows "SP-404", you can fully customize the second and third frames with your own images.

Technical Requirements:

  • Resolution: 128×64 pixels
  • Format: BMP (monochrome, 1-bit)
  • Aspect Ratio: 2:1 (width:height)
  • Color: Black and white only

Upload any image, crop it to the correct 2:1 aspect ratio, adjust the black/white balance, and download the ready-to-use BMP files for your SP-404 MKII.
