APPENDIX A: Using a real Dragon's Lair scoreboard with DAPHNE


1.0 INTRODUCTION

DAPHNE is a Free laserdisc game emulator that allows one to play laserdisc arcade games on one's PC, optionally using a real laserdisc player.  Using DAPHNE, one can play the following laserdisc arcade games (some of which don't work perfectly yet) :

Astron Belt
Cliff Hanger
Cobra Command (running on Astron Belt hardware)
Dragon's Lair (US)
Esh's Aurunmilla
Galaxy Ranger
Space Ace (US)
Star Blazer
Super Don Quix-ote
Thayer's Quest

One can either use mpeg's to simulate the game's laserdisc or one can use a real laserdisc player and a real laserdisc.  Video overlay only works when using mpeg, but some games (Dragon's Lair, Space Ace, and Thayer's Quest) do not use video overlay, so a real disc would be a more pure experience in this case.

DAPHNE is available for either GNU/Linux or Windows 95/98/ME/2000.  If you haven't yet been enlightened by GNU/Linux and are still chained in the Windows world, then Windows 2000 is recommended and Windows ME is specifically recommended against.  If you were one of the poor saps suckered into installing ME, then we pity you and urge you to switch to GNU/Linux immediately errr I mean switch to Windows 2000 immediately.  Not many people have tried DAPHNE with XP yet, but if I were to guess right now, I'd say that it probably sucks (Windows XP, not DAPHNE .. hehe).


2.0 REQUIREMENTS

 

Software Requirements

GNU/Linux 2.2 or better

Windows 95/98/ME or Windows 2000

SDL 1.1

DirectX 5, latest video card drivers

Xfree86 4.x with Xv support _highly_ recommended
If using mpeg instead of a laserdisc player, you'll need video/audio files to approximate the laserdisc video.

Appropriate laserdisc game's ROM images

Hardware Requirements

Utilizing an Actual Laserdisc Player

Utilizing MPEG Video

Pentium 100 MHz PC or better with 16MB RAM and available serial port

Pentium III 500 MHz PC or better with 128MB of RAM and DirectX 5 compatible video card.  For best performance, consider a 1ghz machine with 512 megs of RAM :)
Compatible laserdisc player (See supported laserdisc players ) A video card capable of YUV hardware acceleration is highly recommended.  TNT2's are cheap and work great for this.
The arcade game's original laserdisc

Optional Hardware

Sound card (though highly recommended)

Actual Dragon’s Lair scoreboard PCB

2.1 MORE ON REQUIREMENTS

If you plan to use a real Laserdisc Player

NTSC or PAL laserdisc players will work.    Everyone in the US and Canada will want an NTSC player. Other parts of the world, such as Europe, use PAL.

You will need to get a cable for your player. Cables can be purchased at Radio Shack and CompUSA, or anywhere that Belkin products are sold. You can buy direct from Belkin as well. The cable you want depends on the type of laserdisc player you have.   Cable information can be found under the Laserdisc Player Setup section of this documentation.

ROM Images

The ROM images are the software from the arcade that accepts the user's input and controls the original laserdisc player.  Some ROM images also control video overlay.  DAPHNE uses the original software from the arcade machine to run the emulated hardware. The ROMs are not included with DAPHNE for legal reasons.

MPEG files

No doubt most people will be wondering where to get MPEG files to play these laserdisc games.  The official answer is, make your own using video capture equipment and an original laserdisc that you own.  A guide can be found here .  Since we know many people won't like that answer, let us remind you that this is a free project worked on by volunteers and you are not obligated to use it at all.  Also, some of you may want to check out Digital Leisure 's products.  They sell commercial versions of some laserdisc games and we encourage you to buy their products.  We vehemently discourage any piracy of Digital Leisure's products and will aggressively stamp it out wherever encountered. 


3.0 INSTALLATION

3.1 WINDOWS INSTALLATION

1 - Unzip the daphne .zip file into a directory of your choice, being sure to preserve directory structure (c:\daphne works fine). 
2 - Place the uncompressed game ROM images into the appropriate directory within the ROMS directory.  Note:  A text file exists in each of these directories that outlines which roms are required.  

3.2 GNU/LINUX INSTALLATION

NOTE : It is expected that you have write access to the daphne directory and to the directory that houses the mpeg files (if applicable).  I realize that some linux users will not like this, but it suits me just fine for now.
1 - Extract the daphne .tar.gz file into a place where you have write access (your home directory is fine).
2 - Put the uncompressed ROM images for any game you want to play inside the game's folder in the 'roms' subdirectory.  A text file exists in each of these directories that outlines which roms are required.


4.0 LASERDISC PLAYER SETUP

If you are utilizing MPEG for your video source, you can skip this section. 

DAPHNE controls the laserdisc player by means of serial cable that runs from the back of your computer into the back of the laserdisc player. The type of cable you need depends on the type of laserdisc player that you have. 

4.1 SONY LASERDISC PLAYERS

Sony players are by far the easiest Laserdisc players to setup and people who use DAPHNE seem to prefer Sony laserdisc players over other choices. For the Sony players, you'll need a standard null-modem cable or a regular serial cable with a null modem adapter. They can be purchased at Radio Shack. One end of the cable should have a male 25-pin RS-232 type connector to connect to the player. While older computers have a 25 pin serial port, most newer ones only have 9-pin serial ports. Make sure you buy the right cable and/or adapters for your rig! 


You also will need to make sure the dip switches in the back of your player are set to operate at 9600 baud (or 4800 if you really want to). A Sony player usually includes a diagram on the back that shows how to set the dip switches properly. 

To test your Sony player, download the program LDP.EXE and run it. If LDP.EXE can control your player, then DAPHNE will work. 

4.2 NEWER PIONEER LASERDISC PLAYERS

Most of the newer Pioneer laserdisc players have an odd 15-pin connector in back. Cables that fit this 15-pin connector are rare and, as far as I know, can only be purchased from Pioneer directly ! The cable you want depends on what type of serial port you have on the back of your computer. If you have a 25-pin serial port (older computers) you will want part # CC-03. If you have a 9-pin serial port, you will want part # CC-13. Mentioning the part # to the person you talk to at Pioneer will likely help a great deal since they will probably have no clue what you are talking about otherwise =]. If you know what you're doing, you can also make your own cable

You also need to set the dip switches in the back of your player. Some Pioneers operate at 9600 baud, others only operate at 4800. DAPHNE can handle both. There is usually a diagram on the back of your player that shows how to set the dip switches properly. 

To test your Pioneer player, download the program SVC.EXE and run it. If it works without giving errors, DAPHNE will work.  Note:  This utility may not work under Windows NT/2000.

4.3 PIONEER LD-V6000 LASERDISC PLAYERS

The LD-V6000's use a straight (NOT NULL) 25-pin serial cable, which is a lot better than the 15-pin cable that the newer Pioneers use. Connecting the LD-V6000 to your computer is easy because 25-pin serial cables are very common. 

You also need to set the dip switches for the LD-V6000's. The dip switch settings are documented here.

To test your LD-V6000, download this program. If it works without giving errors, DAPHNE will work.  Note:  This utility may not work with Windows NT/2000.

4.4 HITACHI VIP9550 (and compatible) LASERDISC PLAYER

Hitachi players need a STRAIGHT 25-pin cable.

4.5 PHILIPS LASERDISC PLAYERS

Philips players need a customized serial cable which is outlined in the philips.cpp file in the source code.  I don't have the info handy at the moment hehehe.



5.0 RUNNING DAPHNE

5.1 BEGINNER

The easiest and quickest way to play is by using the Graphic User Interface (GUI). The GUI is currently only available in the Windows version.

1 - If using an MPEG, be sure your framefile is pointing the the correct path.  Please see the DAPHNE Laserdisc Conversion Tutorial for more information on framefiles and creating a DAPHNE compatible MPEG and OGG.  A sample framefile has been provided in the archive named dl.txt.  

2 - After double-clicking DaphneLoader, you will be presented with the above screen for game selection.  Your first task is to click on "configure" for the game of your choice.

3 - There are a number of options within the configuration tabs that are fairly self explanatory.  If utilizing an actual laserdisc, you must select the correct laserdisc type under the "general" tab.  The other critical settings are stored under the "laserdisc tab"

4 - If using MPEG, select "Virtual LDP" for the player type and specify your MPEG Information File.  For laserdisc, select the appropriate laserdisc player and designate the correct serial port and baud rate.

5 - Click "OK" and your settings will be saved.  You can then click on "Start" and if all goes well, the game will begin.  It takes a few seconds for the ROM to initialize itself.

6 - If something goes wrong, read the troubleshooting section.

5.2 EXPERT

DAPHNE can be manipulated exclusively through the command-line in both Windows and Linux.

These expert instructions are not intended to replace the beginner instructions, only to append to them. Not everything covered in the beginner section will be repeated here. 

A typical command-line invocation looks like this for mpeg: 

daphne lair vldp -framefile lair.txt -fullscreen

A typical command-line invocation looks like this for a real laserdisc player:

daphne lair pioneer -baud 9600 -port 1 -latency 10

5.3 COMMAND LINE PARAMETERS

These commands are sequenced in the order in which they should appear in the command line:

SELECT GAME TYPE:  Possible options:  lair, ace, dle, cliff, gtg, superdon, sdq, sdqshort, thayers, speedtest, seektest, cputest, fftest, ffr, astronp, esh, astron, galaxy, laireuro, blazer, cobraab

LASERDISC PLAYER TYPE:  Possible options:  sony, pioneer, v6000, hitachi, philips, vldp, noldp, combo (combo allows a LDP and VLDP to run simultaneously)

FRAMEFILE SPECIFICATION:  (only for vldp or seektest)  -framefile <filename>  (specify full path to framefile if not located in root of Daphne directory.)

DISABLE SOUND:  -nosound

EXTERNAL SCOREBOARD:  -scoreboard

EXTERNAL SCOREBOARD PORT SPECIFICATION:  -scoreport <value>   Specifies which parallel port is connected to your external scoreboard (if you've indicated that you have one).  0 means LPT1, 1 means LPT2.  Default is 0.

SERIAL PORT SPECIFICATION:  (only for LD players)  -port <value>  Specifies which serial port to use.  0 is the first serial port (COM 1), 1 is the second, and so on.  Default is 0.

BAUD RATE SPECIFICATION:  (only for LD players)  -baud <value> Specifies which baud rate to use.  9600 baud is the default.

LATENCY:  (for VLDP and LDP)  -latency <value>  Sets the search latency. This is how long, in milliseconds, that Daphne will pause before searching for a frame.  If you see frames at the end of a scene that you're not suppose to see, adjust this settings.  Default value is 0. 

FULLSCREEN:  -fullscreen  Sets MPEG video to play in fullscreen mode.  If using a real laserdisc player, this paramater is applied to the virtual scoreboard.

LASERDISC TYPE FRAME MODIFIER:  (for LD only)  Possible options:  -pal_dl, -pal_sa, -pal_dl_sc, -spaceace91

DIP SWITCHES:  (For DL and SA only) -bank <bank #> <switches>  Bank # is 0 or 1 for DL and SA and the switches are positioned as follows:  76543210.  Example:  -bank 0 00110000 (would turn on switches 4 and 5 on bank 0)

A .0 Appendix A - Using a real Dragon's Lair scoreboard

DAPHNE can use a real scoreboard from a Dragon's Lair cabinet. To do so, you will need to make your own cable because Robert DiNapoli chose the pin-outs for this cable arbitrarily so you won't find any compatible cables out there.
On one end of the cable, you need a 16-pin Symbex connector that plugs into the back of your Dragon's Lair scoreboard. It looks like this:

On the other end of the cable you will need a 25-pin connector that plugs into your parallel port on your computer. Here is the one Rob made for me :

NOTICE that two of the wires are not connected to anything! These wires are for +5 volts and ground. I have been using my PC's power supply to provide the +5 volts and ground. Of course you can use any +5 V source. The red wire of my PC's power supply is +5 and the black one next to it is ground. DON'T TAKE MY WORD FOR IT! IF YOU DO THIS WRONG YOU WILL RUIN YOUR SCOREBOARD SO DOUBLE CHECK BEFORE YOU DO SOMETHING FOOLISH. I OF COURSE WILL NOT BE HELD RESPONSIBLE FOR ANY DAMAGE THAT OCCURS TO YOUR HARDWARE BY ATTEMPTING THIS VERY OPTIONAL HACK.
Finally you will need to know the pin-outs to construct the cable.
