Thanks to ongoing work on no_std, people continue to try running Bevy on unusual platforms.

Today, @Mathspy from Discord managed to run it on the Playdate:

For what it's worth, Bevy's app, ECS, math, state work on the playdate with no patches
And Bevy's time works with a minor patch https://github.com/bevyengine/bevy/pull/17577

For rendering they're making playdate render calls in PostUpdate: https://github.com/Mathspy/bevydate/blob/1b4f02adcde079cf9757fd3c7d20331c9ab04513/src/lib.rs#L429-L441
