General Remarks |
- BIOS
You'll need an image of the BIOS of a genuine NEOGEO CD.
Copy it in the neocd folder and run STRIP.EXE <name of your bios file> to convert it
to a format understandable by NEOCD.EXE.You can then delete STRIP.EXE and your old BIOS
file.
NEOCD now contains a validity check. It'll only start if you have a 100% valid BIOS.
- Use of the ALT-TAB shortcut key
As Windows is unable to restore video modes used by NeoCD you should NEVER use
ALT-TAB.
- Windows Hostile Mode
This mode disables Windows Multitasking. When NeoCD runs all Windows applications
will be frozen. This includes WinAmp, and any CDR Burning software. You've been warned !
Some computers crash in this mode...
- Special Keys
Use tilde key to return to GUI. (Tilde key is just above TAB)
F12 Takes a snapshot (SNAP*.PCX)
- Changing Game CD
If you want to change game while NeoCD is running, you must inform the emulator
that you have changed the CD. In system Settings, press the button 'Force Reload'.
- Sound card
Your sound card is automatically detected. If for some reasons it fails or crashes, you
can change the soundcard variable in neocd.cfg. The following soundcards are supported :
- Sound
Blaster 1.0
- Sound Blaster 1.5
- Sound Blaster 2.0
- Sound Blaster Pro I or II
- Sound Blaster 16/ASP
- Sound Blaster AWE32
- Windows Sound System
- Ensoniq Soundscape (Elite)
- Gravis Ultrasound (GF1)
- Gravis Ultrasound Daughterboard
- Gravis Ultrasound Max (CS4231)
- AMD Interwave-based
- Pro Audio Spectrum (Plus)
- Pro Audio Spectrum 16
- Sierra Semiconductors Aria
If, unfortunately, your soundcard is not supported at all, you'll have to disable sound by
setting soundcard to 0. You'll also have to disable sound card if your machine is not
capable of giving constant 60 fps.
If sound is active (soundcard # 0), if you set sync to "none", you won't get
more than 60 fps. That's for sound synchronization. If you want to get more than 60fps
(why?), disable sound...
|
Config File Only Settings |
The following variables can ONLY be changed in neocd.cfg file. See remarks
in neocd.cfg file for more explanations.
- windows_hostile: Disables Windows
multitasking.
- keyboard: Selects keyboard layout.
- language: Select language of Allegro error
messages.
- gamma correction: Color correction for your
monitor.
- soundcard: Your soundcard type. Leave it to

|
GUI Options |
- Video Settings
Graphics Driver: You should always use VBE2.0 linear mode. Avoid banked or
VBE 1.x modes.
Resolution: 320x240 or 320x480 scanlines if your GFX card supports it.
Synchronization: If your machine is fast and your GFX card supports it, you should
use VSync. Use speed limiter in other cases. Select None if you want to run at full speed.
Show FPS counter: Displays Frames Per Second counter when checked.
- Audio Settings
Here you can adjust sound and cd audio volumes.
- Joystick Settings
This dialog box is similar to keyboard setup, except it has a Joystick Type
listbox and a 'Change' button. To only calibrate joystick, you can hit 'Change' button
without changing joystick type.
- Keyboard Setup
This dialog box is divided in two listboxes by player. The left listbox contains
keys, while the other contains "actions". You can use the "Get" and
"Set" buttons to know or set keys associated to actions. The exchange button
exchanges keyboard configurations for player 1 and player 2.
- Machine Settings
Console nationality: Choose from Japanese, American or European machine.
Changing this setting automatically does a reset and forces reload.
Reset: Guess...
Force Reload: Use this if you want to change your game CD.
CD Drive listboxes: Select a drive in the listbox, then hit Change button.
! WARNING ! Don't expect to get CDDA sound if you select as CDDA replayer a drive that is
not connected to your sound card :)
- Select Macrokeys
This dialog box allows you to select macro key sets for player 1 et player 2.
Editing Macro Keys
MACRO.CFG file format :
_ Sections are specified between []
_ Sub-Sections are specified between <>
[game name] (see Cheats for more explanations)
<character name or whatever you want> (you must
put your macrokeys in a subsection)
description = 236+AB
In this example macrokey is 236+AB where :
236 represent joystick directions (look at your numeric keypad)
Special case: 5 = neutral position
+ links buttons with joystick position
AB are buttons to be pressed.
236+A outputs: (2) (3) (6+A)
236A outputs: (2) (3) (6) (A)
- Debug Mode
This little dialog box allows you to play with debug mode of games.
The checkbox activates debug menus when checked. You can also mess with the "debug
dip switches"
See Debug Mode Guides
- Cheats
This dialog box allows you to select cheats predefined in cheats.cfg.
CHEATS.CFG file format:
_ Sections are specified between []
_ Sub-Sections are specified between <>
Each section represents a game name, this game name is readed from Neo Geo program header.
To know the exact name of a game, fire NeoCD, run your game then return to the main menu.
Click on Cheats, an alert box will pop-up saying <game name>: No entry for this game
in cheats.cfg. The name you type as cheats.cfg section must be an EXACT match of the name
given by this alert box. Example: For Fatal Fury Realbout Special it is "REALBOUT
SP"
You MUST enter codes in a <codes> section.
Example entry:
[game name]
<codes>
description = WDEADBEEF
In example code is DEADBEEF where:
W is the size of data to write (W=WORD 0..65535 B=BYTE 0..255)
DEAD = hexa offset from address $100000.
BEEF = hexa data to write each VBL.
It is not exacly the same layout as NeoRAGE's game genie, to use a game genie code, simply
add W before it. But beware: Memory mappings are often different and many codes just won't
work. The only reliable way to find cheats for now is disassembling main PRG file.
More to come: A <patch> section with interesting possibilities !

Tech Info |

STARTUP.BIN Is an image of the system memory of a genuine NeoGeo CD at boot time
NEOCD.BIN Is the BIOS of the NeoGeo CD (it is not provided!)
MEMCARD.BIN Is the 8Kb battery backed RAM.
KEYBOARD.DAT File containing keyboard layouts from Allegro (editable with Grabber)
LANGUAGE.DAT File containing locale for Allegro error messages (same as above)
CWSDPMI.EXE DMPI Server to use under pure DOS.
- IPL.TXT:
NeoGeo CD processes a file named IPL.TXT (Initial Program Load) before starting
the game.
Each line consists of filename, bank, offset and is terminated by a CR/LF
Ex: FOO.SPR, 4, 3C000
- Upload:
Software can upload data from main PRG memory to other zones by calling BIOS.
Entry point is C00546
Parameters are located in PRG memory at:
10FEF8.L: Source Addr
10FEF4.L: Dest Offset
10FEDA.B: Dest Zone
10FEFC.L: Block Size
10FEDB.B: Bank number
Zone numbers: (x means don't care)
x1 FIX
x2 SPR
x3 Z80
x4 PCM
x5 PAT
Remarks of filetypes also applies. (See how can I emulate additional hardware)
- BIOS exit:
Called by software to return to CD Player. Entry point = C0055E
|
Q&A |
- NEOCD uses my first cdrom unit, but
I would like to use my second unit which is faster
Modify parameter cdrom= in neocd.cfg to meet your needs.
- My keyboard is all messed up (Q=A
and so on)
Configure you keyboard type with keyboard= in neocd.cfg
- I can't get any CDDA sound...
Please verify that the CD-ROM unit you selected as CDDA replayer is the one that
is connected to your sound card ... :)
- I get an "error while
processing IPL.TXT" error.
You have to check the following points:
- You have configured your cdrom unit in "machine settings"
- You have inserted your cdrom, and have waited some time to let it read directory.
- File IPL.TXT on your cdrom is readable.
- Open IPL.TXT with notepad and test all files mentioned in it (by copying them somewhere)
