    • Done
    • Palette handling needs refactoring
      • Palettes are used in various places inside and outside the Fuse executable (Display code, PNG file handling, FMF movie file conversion) etc.
      • Palettes can vary between hardware (ULAplus/Timex)
      • Supporting limited palette UIs (FB, SVGAlib, portions of Xlib) makes refactoring more difficult due to limited access/interest for development

[Philip Kendall]

Looks like we're getting there with this. Bug #344 is still open, but Berto and Sergio seem to be getting somewhere with that. Fred, what do you think needs to be done for validating the 2Kb page size change?

Is there anything not listed in "Required" section above that people think is critical for v1.2?

[Fredrick Meunier]

For the page size change, I think we need to inspect all use of the MEMORY_PAGE_SIZE macro for assumptions that it is any particular size. I think the snapshot code is the main affected area and we will need to incorporate testing snapshots for all hardware for the release.

I made a start on this yesterday, untested WIP results attached here.
