Merge the new video code, which fixes many long-standing issues.
This also implements Video 4 effects and mosaic effect.
2023-08-26 12:16:49 +02:00

Implement Mosaic effect (for all modes and types).
...
The effect is not pixel perfect, and the code is slower than non-mosaic
code. However this is intentional to ensure rendering is not very slow.
This improves most games that use this effect, and it's definitely
better than not having it.

other games.

Accounts for number of cycles per scanline and stops pushing objects
that go over the limit. Reversed processing from high to low priority
and drawing from low to high.

Fixes most games that had coloring issues finally :)

Backport VRAM mirroring issues for OBJ rendering
...
When using a big sprite with a tile at the end of the 32KB VRAM block it
might end up reading past the 32KB block. This is not an "issue" since
the VRAM wraps around within the 32KB block.

Reimplement sprite copy-mode for obj-based windowing
...
Seems it fixes a couple of visual issues in games too.
Might need to re-check that we do not overdraw too much to avoid
performance issues.

Don't update background scanline params in mode 0

Noticed that an issue with Rayman 3 Hoodlum Havoc was reported on one of the gpsp compatability lists. Cross-checked against mgba and revealed the same issue reported as being present in an earlier version -
https://github.com/mgba-emu/mgba/issues/377
This PR applies the same fix as used in mgba. Could affect other games also.
