Implement sprite limit
...
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.

Fix ST-OBJ blending
...
This uses an extra bit and does proper color stacking when needed to
ensure we render things correctly when ST-objects are visible.
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.

Remove last macros, fix sprite alpha blending

Fixes many games, might break one or two in some weird cases.
Needs some cleanup, and bitmap support for color effects
2023-07-29 00:51:07 +02:00

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.

Bitmap mode does not really support this yet, therefore color effects

Improve GBC sound by fixing its deferred rendering
...
This fixes many games that use the PSG, particuarly the noise generator.
It is very noticeable in explosion/collision sounds with Sonic and Kirby
games, where the noise channel is rapidly tweaked.

Fix reset() issue with dynarec flushing
...
On a reset bios_swi_entrypoint can end up pointing to code over the
watermark, due to block_lookup_address_arm looking up the function
instead of translating it.
Fix it by making flush and init different functions (albeit similar).
Tested by running and resetting games automatically, causing ~10% of
games to crash.

The mismatch causes one-of errors for instruction 0F000000 (swieq 0)
