FD1089 update [Nicola Salmoria, Charles MacDonald]
Improved decryption logic
Added complete table for Enduro Racer
Added more data to Super Hang On Table
Increased the amount of adjustable memory banks from 24 to 32. [Nathan Woods]
ST-V Update [Angelo Salese]
-Started to work with the A-Bus protection,it is a sort of data transfer with the
cartridge area,more info in the stv.c file.
Current implementation just fixes character selection screens in sss,I will work out
about this one in the future,it has various "interesting" issues which was thought
to be emulation probs(i.e booting in rsgun,textures in elandore etc.).
-Added a preliminary timer 1 irq handling,it fixes pblbeach booting but it doesn't
work yet because of incomplete VDP-1 emulation.
-Noticed that ignoring VDP-1 long word access read by SH-2 isn't correct and not
needed (because sss is protected rather than using an illegal procedure),it was
causing wrong graphics in fhboxers & boot errors in pblbeach,reversed it back to
default.
Added missing Player 2 controls to Space War (Leijac) [Steve Ellenoff]
Pacman Driver Update [Dave Widel]
Sets added:
jumpshtp: prototype from PokeMAME
vanvanb: bootleg but it looks earlier.
sprglobp: Not sure if this is the official set, or an accidental merged set with
the glob.
ctrpllrp: I consider this sig. since it came in it's own cab, and they did change
some of the music.
Other changes:
Added full memory map, this should fix the ending of Ms Pac.
Added a jumpshot dip.
I didn't remove any sets, but I mentioned which of them are junk imo and why.
Pacman Driver Update [smf]
* pacman/pengo/jrpacman use the same tile/sprite decode, palette decode & sprite
rendering
* renamed pengo sound & video hardware to pacman as it was used their first.
* converted to use tilemaps
* merged memory maps
* added rom mirroring to pacman & moved any game that needs another rom into
another map.
* tidied up the mirroring in the S2650 games.
* grouped the GAME() lines by hardware and then year.
* moved jrpacmbl back into pengo.c
Emulated protection in Golden Axe ROTD [Charles MacDonald, David Haywood]
Fixed 65816 dasm error [Nathan Woods]
Minor Debugger Fix [Nathan Woods]
Removed the VK_HOME and VK_END cases for the WM_KEYDOWN event. As far as I can
tell, the default action does the trick, and additionally, Shift+Home and
Shift+End are also handled correctly.
Added standard set of Mahjong Inputs [Aaron Giles]
Arcadia Update [Mariusz Wojcieszek]
- changed driver to use multi bios setup
- added support for TenPlay bios (from 10 games board)

writes above chip ram
Operation Thunderbolt Update [Nicola Salmoria]
- verified and coumented from schematics
- emulated external volume and panning control
- added othundrj (region byte change)
- fixed garbage graphics on startup with a kludge (othunder074u1gre)
- also fixed wrong plane graphics at the end of the game (othunder074u1gre3)
but I have no idea how! I completed the game three times and it's not doing
it anymore.
Tilemap Update [Aaron Giles]
Added a user_data field for tilemaps. You can call tilemap_set_user_data() to
set this field internally in the tilemaps. Before rendering, this value will
be copied into the (new) global tile_info.user_data field, so that your
tilemap callback can use it
Kaneko update in preparation for data from Blood Warriors [Sebastien Volpe]
Preliminary decryption of Shisensho II [Pierpaolo Prazzoli]
note: still being worked on
Erotictac driver update [Tomasz Slanina]

Slight change to the Arcadia Driver [Nathan Woods]
src/drivers/arcadia.c:
src/includes/amiga.h:
src/machine/amiga.c:
- Refactors code specific to the Arcadia arcade system and the Amiga
computer out of src/machine/amiga.c into callbacks. This allowed me to
get rid of all #ifdef MESS code out of src/machine/amiga.c
ST-V updates [Angelo Salese]
-Fixed a bug with the VDP-1 ram reading,
SH-2 can do byte or word access, it's implicit that can't do long word access.
This fixes the Steep Slope Sliders booting so the game now works.
-VDP-1 PTM's "draw by request" was actually causing sprites to flicker in
kiwames,reversed back to old implementation until I or somebody else understand
what the current issue is (clear_framebuffer?)
-Finished the game header update,let me know if you like/don't like the system
used for the description of the games.
-fixed a ST-V visible area incorrectness which was causing Virtual Mahjong 2 to
crash after the sound ram check
-fixed a window effect bug in Double-density interlace mode,this fixes some
graphics in vmahjong & myfairld.
-Guessed a bitmap positioning issue in double-density interlace mode,this fixes
the NBG1 positioning in myfairld.
-My Fair Lady now works but only with sound disabled.I have not removed the
NOT_WORKING status due to that.
New Sound Functionality [Derrick Renaud]
Took Frank Palazzolo's DISCRETE_FILTER2 code and made it work outside of the
discrete system.
See sound\filter.h for new functions.
Added op-amp bandpass filtering circuit to sound\namco54.c

------
Thanks to Pierpaolo Prazzoli (Reip) for putting together the 0.90 release while I was away
General Improvements
--------------------
FD1089 decryption [Nicola Salmoria, Charles MacDonald]
- 100% accurate emulation of FD1089A, FD1089B should be considered 99%
because it will have to be verified with other CPUs (it is 100% for all
currently supported games).
- complete tables provided by Charles MacDonald for 317-0018 (Action
Fighter), 317-0022 (Dunk Shot), 317-0168 (Aurail).
- partial tables derived by comparison with the unencrypted versions for
Enduro Racer, Alex Kidd, 317-0024 (Time Scanner), 317-0033 (Alien Syndrome,
3 versions), 317-0027 (SDI). (actual working cpus are needed to obtain full
tables)

* sdioj controls hooked up
* timescna sprites fixed

Ghost, and there is now a 1-pixel column error on ddcrew's attract mode.
These are known issues that I will try to address soon.
