Flicker Converter 0.9 & Player 4096 colors picture player

Flicker Converter 0.9 & Player

Flicker Converter is a graphical tool that recreates the classic “interlaced flicker” effect used on vintage systems such as the Amiga — where alternating two low-color frames at high frequency tricks the eye into perceiving more colors and resolution.

You can also use this tool as an image converter for the Micro 8 — simply keep one of the two generated images.

Main features

Converts any image into two 400×240 indexed framesthat flicker at 50–60 Hz for a perceived 4096 color palette effect.with potentially 240 colors displayed.
Creates independent 16-color palettes (4-bit) for each frame using OKLab perceptual clustering over a 12-bit RGB333 gamut (512 colors).

Offers multiple dithering modes:

• Floyd-Steinberg
• Atkinson
• Bayer 4×4 / 8×8 (with adjustable strength)
• None (flat quantization)

Realtime preview of both frames and live flicker simulation.

Exports true 4-bpp PC BMP files (400×240, 16 colors, ~48 KB each) —ready for loading in Micro-8 Flicker player.

Usage

Open an image (recommended 800×480 RGB).
Choose your dithering mode and strength.
Click Render to generate both flicker frames.
Preview the result in realtime (toggle flicker at chosen frequency).
Save the two resulting frames as PC BMP 4-bpp.

 

and the Win32 tool  



 

Version 1.0

• The Windows tool now saves directly in the Micro-8 .IMG format and no longer uses PC BMP.
• You can also use the Windows tool as a standard image converter (any input image is resampled and exported as .IMG).
• Includes a file selector to choose which picture to display on the Micro-8. It supports:
  • single .IMG images, and
  • flicker pairs: select xxxxxA.IMG first (the tool will search & loads xxxxxB.IMG).

Tips:

• For flicker mode, ensure both files have the expected naming (A / B ).
• You can also keep just one of the two generated frames if you want a single non-flicker image.

Please note that the flickering image creates the visual impression of a 4096-colour palette, but in practice only around 240 colours are displayed at any one time.
You can increase the number of colours shown by updating the palette more frequently —, using display list — but that’s another story
