Pixel Vision 8’s tool supports a palette mode. This forces the tools to split the color memory in half. The first 128 colors are reserved for unique system colors and the other 128 colors will be split up into 8 palettes of 16 colors each. It also activates a new game palette panel in these tools which allows you to preview swapping sprites.
If you want to create a more authentic 8-bit experience while making your game, you may want to consider using palette mode which also opens up the ability to take advantage of palette swapping at runtime.
