It's been a long time coming

It's been about 6 months since I tagged a new release and a lot has changed.

Daft Freak has, as usual, been an absolute legend; carrying the torch with numerous 32Blit software improvements while we've been tangled up surviving lockdown.

The codebase has moved forward to embrace C++17 features such as string_view, which now requires a minimum GCC version of 7, which added experimental support for these features. Ubuntu 20.04 is recommended and includes GCC 9. @Daft-Freak also supplies a PPA with a GCC backport for 18.04 users.

New Tooling Requirements

  • CMake minimum version is now 3.8
  • GCC minimum version is now GCC 7
  • Python minimum version is 3.6

Screenshots

@Daft-Freak has graced 32Blit's firmware with the ability to dump the framebuffer into a .bmp file.

Just use the "Take Screenshot" option in the menu, and a numerically ordered "screenshotX.bmp" will be saved to the SD card.

Palette Mode

Also gracing this release, albeit it's been around for a while, is palette mode. We don't know if this is its final form but it makes a lot of sense for DOS ports. If my lockdown-addled, tired and rusty memory serves it was added by @Daft-Freak to support his DOOM port - https://github.com/Daft-Freak/32BlitDoom

Nicer Firmware Menu

@Daft-Freak has also ported some of our firmware menu enhancements into the master branch, this - at long last - brings the ability to have more games on 32Blit than is possible to fit on a single screen.
