bit.

Implement EEPROM save override.
...

override games via gba_over too

Rework RTC and break it into GPIO, with RTC and Rumble (GPIO3)
...
This adds Rumble support for GPIO3-enabled games (Drill Dozer).

Remove gpsp savegame method in favour of libretro's one
...
This generates 128KB save files (instead of variable sized ones) to
prevent truncated savegames under some circumstances. Most other
emulators have no trouble loading them (and the unused data is simply
ignored).
Remove also config txt file that's now unused.

Improve EEPROM reads/writes and ROM reads
...
Unmapped areas read a value closer to what hardware produces.
Ensure that 32MB games can do EEPROM reads.

Adding DMA transfer "Sleep" mode
...
This accounts for DMA stealing cycles from the CPU whenever the CPU
triggers a DMA (does not affect H/V blank or sound DMAs).
Works by moving the CPU to a PAUSED state where the cycles are accounted
for, reusing a similar mechanism for HALT/STOP.
Fixes a couple of games, notably GTA that has a DMA/IRQ race condition
(likely a bug really) if cycles are grossly miscalculated.

Improve savestate loading to avoid corrupting the current state
...
It should not happen since the magic value and version would normally
discard incompatible savestates, however it's preferrable to check
before loading the state (it's just some minor sanity check).

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.
2023-08-23 21:18:09 +02:00

other games.
