Fixed garou raster effect missing in pre-battle talk
Added proper neopcm2 decryption
NEOGEO-CD
Some code has been rewritten to improve compatibility. Now
more games should work (although there are still some problems).
Added an option in the Emulation menu for direct load of neocd ISO
or CD.
PGM
Added Knights of Valour 2 and Knights of Valour 2: Nine Dragons. Thanks
to HappyASR for the help getting the dump of the internal cartridge
cpu program. Due to the extra processor required to emulate， the game
will require a more powerful PC to run. Also savestates won't work.
(Internet ranking mode for kof2nd has been intentionally disabled).
Music speed in kov2/kov2nd is a bit off.
Fixed wrong sprite zoom and shrinking (required for kov2nd)

in speksnk.net boards
2.24
NEOGEO
Fixed all the neogeo roms to match MAME romsets (Thanks to
Wesker from Speksnk for the work).
Fixed kof98 protection (delete old kof98.srm files from
your config folder)
GENERAL
Added HQ2x plugin (includes src in plugins\hq2xsrc.zip)
2.23d
NEOGEO CD
Fixed broken neogeo CD in the previous version
Fixed some protection issues in Soccer Brawl， I hope
it also fixes the Disc I/O errors.
PGM
Fixed broken pgm support in previous version
GENERAL
Hopefully fixed the .dat files
2.23c
CPS2
Added new cps2shock xor tables
Added 'Crouching Tiger Hidden Dragon 2003' game.
NEOGEO
Fixed some problems with multislot emulation when there were
empty slots between 2 used slots.
Synced game drivers and bios names with latest MAME.
2.23b
CPS2
Added Mighty! Pang (Japan 001011)
Added Super Street Fighter 2 (ETC 930911)
NEOGEO
Added Jockey Grand Prix. The sound program rom is
encrypted， so I've used vliner as parent and took
its m1 rom while we get a decrypted dump.
GENERAL
Added a new frameskip code， it should perform better on slower
machines
2.23a
GENERAL
Fixed the NOREPEAT flag not working in winamp jukebox lists.
2.23
CPS2
Added 1944: The loop master (US 000620)
GENERAL
Improved the winamp jukebox feature， check the sample.trk file
in TRACKLST for an explanation.
2.22a
Seems that the 2.22 version was leaked before release
with some bugs in the main core and the d3d plugin so
I've named this version as “a“ to avoid confusion.
GENERAL
Added a Winamp jukebox option. Be careful as it's a
bit different than how Kawaks works. You'll need to create
a music mapping table (check the sample kof98.TRK file in
TRACKLST directory) and nebula will replace the
sound codes you indicate by the mp3/cd track/ogg/wav/...
you specify in that file. You must have winamp running
before loading a game that you created track lists for.
The option to enable/disable it is in the Sound menu.
It only works with Winamp 2.x.
Improved the video plugin interface to support rendering
plugins.
Added a preliminary graphics renderer based in Direct3D. I highly
recommend using it if you want to run in 32 bit desktop
or play rotated games (19xx，dimahoo) as it is a lot
faster than the Hardware Blit one in these cases.
Also it has some projection features and any bright
scanlines. Scanlines doesn't work well with rotated
games.
You'll need a video card with the following features:
- non square textures
- non power of 2 textures
- textures bigger than 256x256 pixels (sorry， no voodoo)
NEOGEO
- Fixed “Step Frame“ button in the shots factory
- Added King of Fighers 2001 driver
CPS1
- Fixed “Step Frame“ button in the shots factory
- Fixed Mega Twins music speed.
- Fixed missing sprites in Forgotten Worlds
- Fixed games crashing on 32 bit desktop
CPS2
- Added Marx Matrix drivers.
- Fixed wrong flash frames in MvsC.
- Fixed some Dimahoo cheats not working (from
the latest Mike_Haggar cheat collection file)
- Fixed games crashing on 32 bit desktop
2.21b
GENERAL
Fixed a severe bug in the startup code that caused nebula
to allocate huge amounts of RAM for absolutely no use on
startup. This was causing crashes in WinXP/2k and wrong
graphics decryption in big neogeo games.
CPS1
Fixed crashing in Punisher in the 2nd stage boss.
CPS2
Improved VBlank timing. Fixes some problems with SFA3.
NEOGEO
Added support for the Universe BIOS. Go to Game->Neogeo Options
and enable “Use Universe BIOS“ to load it. The bios must be in
a zip named uni-bios.zip (in the ROMS folder) and the rom
MUST be named uni-bios.rom. When using universe bios， all neogeo
options and cheats in nebula will be disabled， use the bios built-in
region， machine type and cheats options. When using universe
bios you'll see garbage during initial tests， don't worry， that's
normal and doesn't cause any other problem.
Fixed slowdowns in s1945p.
GENERAL
Fixed crashings if you have more than 4 joysticks connected.
2.20
CPS2
Fixed some sprite/BG desyncs in Gigawing.
Fixed SFA3 crashing with latest Mike Haggar's cheats.
CPS1
Added a bunch of SF2 hacks (not all fully working though).
GENERAL
Added highscore saving for CPS2 games. Not all games are added yet.
Almost all CPS2 games are supported， and some CPS1 too.
It will use an external database to store the highscore data.
You can convert a MAME Hiscore.dat file to nebula's internal DB
with the command “nebula -hiconv“ having the hiscore.dat file in the
nebula dir， it will build HISCORES.DB in the HISCORES dir. You should
delete all the .HI files to avoid problems when you change the HISCORE DB.
To turn off hiscore saving， just delete HISCORES.DB from the HISCORES dir.
1.19c
CPS1
Fixed all CPS1+QSound games crashing after load.
CPS2
Added new decryption tables
- Giga Wing (US 990222)
- Giga Wing (Japan 990223)
1.19b
NEOGEO
Fixed Fatal Fury 2 protection not working
Fixed VLiner not working
Fixed Alpha Mission 2 missing sounds
Added 6 slot support for Multi slot MVS emulation.
Added Bangbead encrypted romset.
CPS2
New xors
- Megaman 2: Power Fighters (US 960708)
- Street Fighter Zero 2 Alpha (Asia 960826)
- X-Men: Children of the Atom (Asia 941217)
CPS1
Fixed wrong tiles on 1st floor of Magic Sword
2.19a
PGM
Fixed gfx glitches in Dragon World 2
Fixed zooming (very noticeable in dragwld2 intro)
Fixed missing parts of some sprites (KOV flashes)
CPS1
Fixed some remaining music speeds...
NEOGEO
Fixed Garou missing animations (esp. some Grant moves).
Select button should be working in all games now (not only garou).
Added the game slot switch button to switch games
forwards (key 9=switch backwards， key 0=switch forwards)
GENERAL
Fixed (hopefully) Romcenter Dat generation.
2.19
PGM
Added Dragon World 2 (it has some gfx glitches due to some missing parts in
the protection emulation)
Text layer should now be correctly aligned (it was 1 line too high)
CPS2
Fixed ssf2xj timing that was still wrong.
NEOGEO
Fixed small autoanimation problems
Added neogeo multislot MVS emulation.
Usage:
in the rom loading screen， you'll see a dropbox to
select in which neogeo slot you want to load the game.
Just select the slot and hit load， then after loading a
game， you can go and load another in a different (or the
same， overriding it) slot.
Note that you'll need a lot of RAM to hold all games in
memory at the same time.
To switch from game to game， use the button mapped as
Button 5 in the input options (default key 0)
The current bios supports 4 game slots.
The default bios config only allows to switch games after
inserting a coin. To change it， press F2， go to “set the soft
dips“， then “setting the cabinet“， and change “Game selection“
to “Free“.
Using savestates with multislot games may have unpredictable
results.
ALWAYS LOAD IN THE 1ST SLOT FIRST.
2.18b
NEOGEO
Fixed some sound timming issues with long samples (Dandy J stage in wakuwak 7)
Switched the memory card format to MAME one (old memcards still work).
CPS1
Fixed slow music in pang3 and megaman.
2.18a
NEOGEO
Fixed mslug3nd driver crashing nebula.
Fixed kof99d driver. now it loads the decrypted C roms instead of
the prototype roms.
2.18

Improved music speed (checked with real sound samples. Thanks to BillyJr).
Fixed some wrong objects in KOV.
CPS1
Fixed incorrect music speed in some games (still some remaining)
Dipswitches in all CPS1 games were wrong. They are (should) be
correct now.(remember that CPS1 dips are changed in the Cheats menu)
Fixed some sprite clipping problems.
CPS2
Added Vampire Hunter 2 and the rest of the latest CPS2Shock releases
NEOGEO
Fixed garou select button
Fixed garou 3rd Terry stage background animation (requires rasters enabled)
Fixed garou random character selection.
Fixed sound problems in ssidekicks4 and neobomberman
Improved raster emulation with the info from the real HW.
Now nebula should not complaing about wrong ng-lo.rom files.
Fixed sound problems ninja combat， ninja commando and others. Big thanks
to Acho A. Tang.
Fixed KOF94 Japan stage intro.
Recent neogeo games have been locked. You should go to an arcade
if you want to play them.
Fixed kof2knd C7 rom (seems that only I had that rom)
Added an additional sengoku3 romset for the new P1 (it's not
clear what's the correct one).
ND romsets no longer use the encrypted P roms， they are
fully decrypted.
GENERAL
Added an option to auto switch to Fullscreen after loading a ROM (Misc menu)
Corrected Nebulaconfig looping in the options screen.
2.17
PGM
Improved sound emulation:
Volume should be correct (or almost) now.
Note pitch improved.
Fixed missing background in a KOV stage.
Added an option to capture the current music to a file
to load it in jukebox (PZM files).
Calendar is disabled when netplay or recording movies. This
will (should :)) avoid desyncs.
CPS2
Fixed some finish specials being wrong in the bottom of
Manhattan stage in mshvsf.
CPS1
Fixed missing helicopters and buildings in cawing.
NEOGEO
Fixed (again) sengoku3 decrypted driver.
Fixed Irritating Maze controls. You can use the mouse to
move the rod (this game cabinet has a trackball).
Fixed missing 2 lines at the bottom of the screen of games
using rasters (most noticeable in mslug2， galaxyf， mosyougi)
GENERAL
Added some language translations (Italian， Korean， Chinese， Dutch)
Fixed 50% scanlines at 640x480
Added a “Step Frame“ button to the shot factories (window mode)
Added some Force Feedback tables by Iron Man.
Added a small skin option to the windowed GUI. Any PNG file in
the SKINS folder will be randomly chosen and displayed in the
nebula window on startup when no game is loaded.
IMPORTANT!! I've received a lot of mails asking about neo-geo.rom，
ng-lo.rom and ng-sfix.rom. Those are the neogeo bios and MUST be
ZIPPED in a file named NEOGEO.ZIP in the ROMS folder (or any roms
folder you have configured).
2.16
PGM
Z80 is fully emulated， that means， correct sounds and music
in games. The sound chip emulation is not 100% accurate so
some notes in music are wrong. I've added an option to disable
the music in the Options menu.
Fixed savestates in KOV games.(old savestates will still not
work， only new ones will be correct).
Fixed text layer position being wrong by 1 line.
Added shot factory (F8)
CPS2
Fixed a palette sync problem that caused part of the charlie
stage in sfa2 flash out of sync.
Scanlines in 640x480 are now correct (again). Use No stretch go
get them correctly.
NEOGEO
Fixed sengoku3 decrypted driver.
GENERAL
Added language switch for the menus (check the english.lng
file in the skins dir for a template for translation)
2.15a
PGM
Fixed Knights of valour missing platform and bridges in some
stages.
Some rom renamings. To match mame names
sango1 -> kov
sango1_5 -> kov115
sango1_9 -> kovplus
orlegend -> orlegend (the same)
orleg112 -> orlegnde
orleg12e -> orlegndc
Fixed china and taiwan regions swapped in KOV
NEOGEO
Fixed savage reign V2 rom CRC
Added Sengoku3 and Zupapa neogeo drivers.
GENERAL
PGM resolution is very wide， so if it's cut in the
screen， play a bit with stretch options till you can
get it fitting.
2.15
PGM
Added Knights of Valour and Knights of Valour Plus
(see KOVROMS.TXT for the correct roms CRC and sizes).
Special thanks to BillyJr for his help to get this
game running.
Added Sound emulation. Well， it's not complete emulation， but
it's enough go get sounds working. Only SFX works and some
sounds may be wrong.
Added region switch to orlegend and kov
Fixed orlegend crashes.
NOTE: PGM games have a very wide resolution so
double size modes (scanlines and most image enhancement
modes) require resolutions higher than 800x600 to work
properly with no stretch.
GENERAL
Fixed netplay crashing with Konami and PGM games.
2.14b
CPS1
Fixed wrong layer offsets in sf2yyc and kouryu (=blackbelt?) that
appeared due to the new timing.
Fixed Quiz and Dragons USA gfx problems
Fixed sound problems in ADPCM audio (oops， my fault， I
left some test code inside).
GENERAL
Fixed Nebula hanging in a window when exiting a game
in the classic GUI.
Fixed the Video menu crash if there are no transparency tables in
the CONFIG folder.
2.14a
CPS1
Fixed loops in some drivers (cworld2j， qad and qtono2)
that were causing the rom scanning crash
2.13a
NEOGEO
Fixed Spinmasters gfx errors on the bottom lines (raster bug)
CPS1
Added SF2 KouRyu driver
CPS2
Improved CPU timing. That makes SSF2T/SSF2X smoother.
Fixed SSF2X driver (no more gfx or sound problems)
PGM
Fixed crashing after a few minutes playing.
GENERAL
Added SuperScale blitter (similar to a *Scale blitter
of other CPS2 emu :)). It looks great and it's very
fast (if not the fastest) image enhancement mode. Full source included.
The best blitter in nebula without any doubt. It only works
in 16-bit desktop modes.
Added auto-transparencies. It will make flickering objects
and meshes become transparent without blur. The 50% frame blend
blitter is no longer needed. Unlike sprite transparencies，
this will cause a performance hit， so better don't enable it
if you have a slow computer.
Fixed full interpolation mode.
2.13
NEOGEO
Improved raster effects emulation.
Most games are correct now， and others
have been greatly improved:
mosyougi title
ssidekicks pitch (still not 100% correct but
heh， at least you can see it)
samsho3 “3D“ floor effects
wheroes floors
karnovr floors
mslug3 last boss red sky distortion
galaxyfight better alignment
CPS2
Added latest CPS2Shock releases
Fixed wrong layer prios on nwarr character
selection screen.
KONAMI & CPS1
Fixed music speed that was wrong in some games.
PGM
Optimized sprite drawing (more than twice
faster now in some critical parts)
Fixed sprite shrinking
Added sprite zooming
Added linescroll (orlegend stage 4 and 6)
Fixed some missing sprites (clipping problems)
Main CPU is running at the correct speed now
GENERAL
Added DSP plugins support (including a DSP
wrapper for winamp plugins. It's still beta
so be careful， and don't change the plugin
while a game is running)
The plugin.h file has been update with the
DSP plugin interface.
Force feedback support is disabled as I'm
improving it (and it's still not finished :()
2.12
CPS1
Fixed dynasty wars romset names
Fixed sprites disappearing.
NEOGEO
Fixed mslug3nd romset.
GENERAL
Fixed Scanlines when using 640x480.
2.11
KONAMI
Added Bucky O'Hare
Fixed Zooming.
Fixed some sprite gfx problems (2nd level boss
in moo)
CPS2
If you are only seeing 2 buttons in CPS2 games
delete the .dat file for that game in the
CONFIG folder.
CPS1
Added SF2 YYC hack
NEOGEO
In the ROMDATA folder you'll find a
file called Neogeo.new. Delete the
Neogeo.dat and rename the .new to .dat
to use the new MAME rom names.
It's a good moment to remember that if
you have nebula reporting missing neo-geo.rom
ng-sfix.rom or ng-lo.rom， you'll need to put
the neogeo.zip file (BIOS) in a roms
directory (folder).
GENERAL
Fixed Vertical games not displaying anything.
2.1
KONAMI
Mooooo!!
BUG FIXES
Fixed old GUI crashing on start
Fixed title bar corruption
Fixed Aspect ratio with Keep aspect option
Fixed vertical games on 32 bits desktop.
Fixed ingame menu letters when using 32 bit
color depth
Fixed xmvsf crash on start bug.
Added shot display on Rom List when moving
with arrow keys
Added a Switch to Fullscreen option in the
Video Menu， as some people didn't know how
to switch to fullscreen (ALT-Enter)
Added many transparency tables. Thanks to
Darksoul， Bad_crc， Razoola， kyo_99 and
Ken_Masters.
Some things I forgot to mention in the readme:
- To use the old gui， you can also launch:
Nebula.exe -classic (-window if you want to
run it in a window))
- You can click on the column names in the rom list
to sort the list using that column.
2.0
GENERAL
Lots of changes in this version， but the most
noticeable one is the new Window mode
GUI (You can still use the old GUI). Note that
the window mode will workin systems with 32 bpp
desktop color depthbut only Hardware blit will work.
If Nebula runs very very slow， try disabling stretch and
Switching to system memory allocation.
Due to the big amount of changes I'd recommend
that you read all the docs.
Some keys behave differently in window mode GUI
check the GENERAL doc.
Major rewrite of the main core. All systems
emulation have experienced a speedup and
the memory requirements have been lowered
a lot.
New shots factories， that allows changing almost
every parameter/sprite. Please， read the doc about
this.
New macro code， that allows macros to work without
knowing the character addresses and also adds
“global“ macros that can be used with any character
(read macros documentation).
NEOGEO
Added 4-point interpolation for Delta-T samples.
Added a decryption progress indication for
latest (encrypted GFX) games.
