Raizing:
- Adjust timing for audio in sorcer and kingdom (again)

- Swap pll properly to 94.5 mhz for SDRAM compatibility, adjust all clocks and frequencies
- Add 2 build profiles for each core, one for development purposes (fast build) can get you an RBF in 8 mins, but not meet timing constraints 100%, and other is normal production build, which is about 20 mins. You can switch between the profiles in quartus UI.

New Core: Pokemon Mini (Nintendo 2001)


Centipede:

- Removed DSS/Covox support (Not feasible for this core)


PokemonMini:

- Renamed option 'Zoom', to '240p Mode' for clarity.
- Renamed 'Shock' button to 'Shock Sensor'.
- Fixed implementation of 2 instructions, affecting at least 2 commercial games.
- Fixed a problem where pushing the power button results in reboot instead of shutdown.

07/09


PCXT:
- Handling of the border colour register in Tandy
- Handling of the NMI register for video memory paging (more compatible games, such as Another World and Ski or Die)

Raizing:
- Override build_id.tcl script to automatically inject build date in cfgstr.
- Fix mapping of fx level option (high=100%, very high = 200%, very low = 50%, low = 75%)
- Adjust default fm level of batrider to 50%.
- (Hopefully) fix issue with scroll layers disappearing when free play dip is set in bakraid

08/09


PokemonMini:

- Fixed sound cracking/popping. This was mostly prominent in the bad apple demo.
- Fixed blitter timing issues. At least one game was known to be affected by this (Pokemon Party mini).
- Reduced overall sound level to be more in line with other console cores.

09/09


SNES:
- GSU & PPU fixes (srg320).
- SNAC auto detect, organize OSD input options (blue212).
- Framework update.


Irem M72
- Support for R-Type 2, M84 hardware
- Added 240p crop option
- Added Analog video h/v adjustments
- Re-organized OSD

10/09


New Arcade Core: Inferno
- Original core developed by darfpga now ported to MiSTer by JasonA and birdybro
- Sound effects don't all play correctly, this is already known.

Supported Game:
Inferno (Williams)

11/09


Inferno:
* Gave joystick analog inputs precedence over digital (d-pad) inputs if both were triggered at the same time. This resolves default mapping issues some users were having if they had not defined gamepad inputs inside the core.

13/09


Inferno:
- Sound from PIA 6821 chip fixed thanks to @darfpga
- Modified fitter settings slightly to meet timing requirements more reliably.


Irem M72

Fixes and improvements from @gyurco
- Support Hammerin' Harry M84
- M84 sample playback rate fixes
- Reduce sprite bram usage


Raizing:
- fix issue with mirrored sprite seam calculation (ie. batrider intro tank missing 1 pixel at the end due to 2 sprites, 1 mirrored, joined at a seam).
- improve performance of obj engine due to lower clock change to 94.5.


New Arcade Core: Galivan
- Support for Cosmo Police Galivan & UFO Robo Dangar


PokemonMini:

- Fixed RTC timer being stuck resetting. This affected homebrew demo SHizZLE.
- Fixed bug which can occur after loading a new rom or resetting the core.
- Implemented remaining jump conditions. This fixes a few hombrew games.

14/09


ao486:
- Fix interrupt controller.
- sound: Updated the DSP write port status busy flag (user7182).
- remove the press-to-see need for joystick to prevent configuration issues in games (Kitrinx).
- Add option to disable joysticks.
- Support for steering wheel.
- Updated framework.

16/09

- Fixed tape loading audio OSD option, by @Flandango

25/09


PSX:

- implement 3 different turbo speeds
- Move datacache into CPU -> speedup when using turbo setting "high"

fixes/changes:
- fixed memory card loading edge case leading to memory card data not being available
- fixed wrong savestate slot index when loading core
- fixed edge case where loading a savestate would hang up the core until reset is triggered
- fixed CPU blockLoadforward edge case (CPU test from pcsx-redux is now pass)

accuracy improvements:
- Memory: CD register bus is now using extbus logic

- Memory: adjust timings for BIOS reads
- Memory: rework sdram -> instruction cache interface, reducing cache fetch time by 1 cycle, fulfilling test against hardware
- CPU: implement out-of-order load pipelining
- CPU: implement readback of CACHECONTROL register
- CPU: make instruction fetch stage fully independent of data fetch stage
- DMA: add timing cost for ram page switch and refresh
- DMA: reduce initial overhead by 2 cycles
- Timer: implement non-retrigger mode by using Mode bit 6
