|

- Added a new agb::sync module that contains GBA-specific synchronization primitives.
|
||||
- Added support for save files.
|
||||
- Added implementation of `HashMap.retain()`.
|
||||
- Added support for affine backgrounds (tiled modes 1 and 2) which allows for scaling, rotating etc of tiled backgrounds.
|
||||
- Added support for 256 colour backgrounds (when working with affine ones).
|
||||
|
||||
### Changes
|
||||
- Many of the places that originally disabled IRQs now use the `sync` module, reducing the chance of missed interrupts.
|
||||
- HashMap iterators now implement `size_hint` which should result in slightly better generation of code using those iterators.
|
||||
- Transparency of backgrounds is now set once in the toml file rather than once for every image.
|
||||
- Palette generation now takes into account every single background a toml definition rather than one at a time, you can now find it in the PALETTES constant rather than in every individual image.
|
||||
- Sound frequency is no longer a crate feature, instead set when initialising the sound mixer.
|
||||
|
||||
### Fixed
|
||||
- Fixed the fast magnitude function in agb_fixnum. This is also used in fast_normalise. Previously only worked for positive (x, y).
