This specifically means that the Lindbergh Blue series can be considered End of Life.
Enough StarHorse2 parts have been sold on YAJ, it is a fair time to help folks attempt to restore these wonderful machines.

This document will serve as a reference guide to how the Sega Lindbergh works. The Sega Lindbergh is an arcade platform developed by Sega as a successor to the Sega NAOMI 2 arcade system. It was launched in 2005 and acted as Sega's "primary" arcade system until the release of the Sega RingEdge platform in 2009. Sega officially stopped supporting some versions of the system in 2018.
The motherboard inside the Sega Lindbergh is effectively an ATX PC Motherboard. The only real change from a standard PC Motherboard is the parallel port header used for the Security PIC and buttons. A CF card slot is also built into the motherboard, which is sometimes found on other industrial type ATX PCs.
There are three graphics cards that were used with the Lindbergh:
Nvidia GeForce 7600
Nvidia GeForce 6800
Nvidia GeForce 7800
Quote: The slow video might be the infamous nvidia cold bios bug? flash the bios on the card with the temp monitoring disabled, as it effects a lot of 7800gs (especially G71) - basically if the ambient temp is below 20 odd degrees, the card think it is overclocking and puts it in throttle mode (which is like 20% power), so games run extremely slooooow.
The JVS card is the main bit of proprietary hardware that sets the Lindbergh apart from a standard computer. A Linux driver for the card is installed on the operating system, and allows the games to communicate with memory stores on the card for saving settings, as well as the JVS line for talking to control interfaces.
The CF card is locked with an ATA password. An ATA password (also known as the ATA Security Feature Set) is part of the ATA specification and allows two 32 byte passwords to be set on the drive; a User Password and a Master Password.
The HDD drive is locked with an ATA password. An ATA password (also known as the ATA Security Feature Set) is part of the ATA specification and allows two 32 byte passwords to be set on the drive; a User Password and a Master Password.
Crediar released tools and notes for unlocking both on Twitter, and on Github

Long lost Crediar Lindbergh makekey tool: https://github.com/ArcadeHustle/LindyLiberation/blob/master/makekey/main.cpp
The extended inquiry 0xEC reply is required to create the keys. The easiest way is to use plscsi this exists for windows and linux and is very easy to use. Just send the following command to get the required bytes:
plscsi -v -p -x "85 08 0E 00 00 00 01 00 00 00 00 00 00 00 EC 00" -i x200 -t inq.bin
Each devices uses a slightly different unlock command again using plscsi will simplfiy things:
plscsi -v -p -x "85 0A 06 00 00 00 01 00 00 00 00 00 00 40 F2 00" -o x200 -f key.bin
plscsi -v -p -x "85 0A 06 00 03 00 01 00 AB 00 00 00 00 00 82 00" -o x200 -f key.bin
The tool will create the bytes for you simply insert them between the ""s
plscsi -v -p -x ""

Games are stored on installation DVDs. These contain a section of custom sega header data followed by an ISO file system with multiple partitions. As explained in the security chip section, one of these partitions contains a bash script to unencrypt the other partitions which contain the game data and executable.
Although there are multiple partitions, most games only use one partition to store all of the files.
Probably should try this and explain better, but this is how you get the data from the DVDS:
- Mount the DVD drive from a USB Drive
- Using a hex editor to search the raw image for “CD001” (ISO Marker), this is found at 0x288000 and 0x390000 on HOTD4.
- Subtract 32768 (0x8000) as per the ISO9660 standard (en.wikipedia.org/wiki/ISO_9660)
0x288000 - 0x8000 = 0x280000 = 2621440
0x390000 - 0x8000 = 3702784
- On a linux machine you can then mount these:
losetup -o 2621440 /dev/loop1 /dev/scd0
mount -t iso9660 -o ro /dev/loop1 /mnt/cdrom/
These two partitions are encrypted. One contains the game data, and the other will contain a bash script that will unencrypt the game data folder. The PIC chip is used to unencrypt the smaller partition with the bash file, which then uses faster decryption for the game. It’s easy to find most of the bash files that unencrypt the game partitions with static keys by finding pre-decrypted Lindbergh images online. Some games use the same decryption keys, so if you find a game that hasn’t yet been decrypted that could be one way to do it. This is explained in more detail in the security chip section.
The sound card is made by Creative, but is branded by Sega. Some of the games require this, and other output on the motherboards onboard audio out channels. I’m still unsure why Sega decided to add a dedicated sound card when the motherboard has one on already that supports 5.1 surround. Games do actively check for this card, so for example Let’s Go Jungle cannot be started without one (unless of course you patched it out).
The Security chip in the Lindbergh is a PIC microcontroller which is connected via a Parallel port exposed on the front of the system. It contains the key needed to decrypt the contents of the smaller data partition from the partitions stored on the installation CD or HDD. Only one partition of the data is encrypted by the PIC Microcontroller, and this partition once decrypted contains a bash script which will unencrypt the rest of the partitions on the drive which contain the game data.
It is interesting to note that some games share the same internal encryption keys used by the bash script. For example Let’s Go Jungle and Let’s Go Jungle Special don’t share the same PIC security chip, however they do share the same internal encryption keys. This means that Let’s Go Jungle Special can be played even though we don’t have access to the original PIC chip.
The security chip also contains a program that will communicate with the game at start up. Each game does this differently, and some don’t seem to check for the key chip at all. Removing the security check from the game is generally doable and can generally be achieved by adding NOOP instructions where the game jumps to the error screen. A good way to get started with this is by getting a pre patched lindbergh dump online and comparing that to a non patched version. This will show the techniques used to get past the security key check.
The PCI card in the Lindbergh contains memory that stores game settings. When a game starts up it’ll try and overwrite the settings with the default ones - this is usually patched out on the playable dumps.
On GitHub there is some code that allows you to save and re-write the information on the PCI card. This software is said to be dangerous, and was recommended not to use it by the creator as it may brick your Lindbergh PCI card. The Jakulous multi however does use this technique even though it was recommended to be dangerous by its creator.
https://github.com/JayFoxRox/lindbergh-tools/blob/master/Utilities/src/backup.c
The next section will talk about the software that runs on the Lindbergh in order of the boot process.
- Boot Process
- Bios
- Grub
- MontaVista Linux Init.d
- SegaBoot (checks everything is in the right order before running the game)
- Game
- SegaBoot -t (the test mode (does no checks for HDD/CD etc))
- Goto 5.
The BIOS can be accessed by plugging a keyboard into the Lindbergh system and pressing Ctrl + Alt + F1. The password for the BIOS is ‘mssvhy’, without the quotes.
The BIOS unlocks the HDD/CF using the ATA password feature normally on startup. This prevents you from booting from any already unlocked device as it’ll attempt to unlock it first. Inside the Advanced options on the BIOS setup there is a feature labeled ‘Secure Boot Sequence’. If you turn this feature off, it’ll no longer unlock the CF/HDD which will allow you to boot of any normal HDD/CD/CF. Please note that whilst this feature is turned off, the system won’t be able to boot from the CF.
To Boot from a HDD you must also change the jumper settings on the motherboard to set the CF card to IDE slave rather than IDE master. I’ve also found that unplugging the CF card is generally a good idea.
It’s also possible to make the boot of the bios much faster by disabling the longer memory check. This generally for me shaves about 2 seconds off the boot time. This with an added 2 more gigs of ram considerably speeds up loading times for the whole system.
The system runs a very old version of Grub 1. There is a separate partition on the disk for grub, which contains all the configuration files and can be modified here. Segaboot Executable The Segaboot executable is the application which shows the large white screen with the Lindbergh text on, which enforces everything is correct on the machine (game chip, hdd etc.). This can be executed in the same way as the other games, however you will need to invoke the xserver first so that the application has something to draw on.
You can provide the -t parameter to the segaboot executable to show the test menu. When exiting out of the segaboot executable test mode, it doesn’t run any of the checks again and just exits cleanly.
The ‘Game Test Mode’ option is only available if the file ‘test’ is available in ‘/home/tmp/’ (this needs to be verified, it could just be ‘/tmp’). Making a bootable development OS To create a bootable version of the Lindbergh operating system, with shell access do the following:
- Obtain a copy of the Linux image from a Lindbergh CF card. There are different versions labeled Rev A to Rev D. Rev A and B run the 2.4 Linux kernel, whilst all other revisions run the 2.6 Linux kernel. Games generally function much better on their respective original kernels.
- Using a command like ‘dd’, write the CF image to a hard disk drive. You may want to write the image to a Sata HDD now that you can use the Sata port on the motherboard. Although this sometimes works, a lot of games don’t work properly through the Sata port and will experience slow downs and issues. A Sata to IDE converter can be used so that you can use an SSD, but it’s pretty trial and error which brands work.
- You will see there are two partitions on the newly created boot drive. One is smaller and contains GRUB1. The other contains the kernel and other files used for the Lindbergh OS. At this point you should enlarge the OS partition to fill the entire HDD. This can be done with something like GParted.
- Mount the OS partition and navigate to ‘/etc/init.d/killallx.sh’. This is one of the last bash files which runs during the boot process. At the bottom of this add the line ‘./bash’. This will cause the system to run bash instead of the segaboot executable that is normally started. If you type ‘exit’ into the bash prompt, the system will continue to boot up.
- Folders containing data can now be placed onto the drive. I normally placed them under ‘/usr/games/’.
- Insert the drive into the Lindbergh and boot up the system. Follow the BIOS section of this guide to learn how to boot from unlocked drives.
- Games run from the ‘/home’ folder and should be symlinked there before they are run. Start by removing the home folder by typing ‘rm -rf /home’. Now symlink a game to the home directory by typing ‘ln -s /usr/games/lets-go-jungle /home’. Now you can run the game executable from home by typing ‘./home/run.sh’.
- To run the test mode of a game, suffix it’s startup script with -t (works on most games). For example Lets Go Jungle test mode would be run with ‘./home/run.sh -t’.
Game uses the guns in reverse (x=y,y=x) to every other Sega gun game. Patching out the key chip check on this game is very simple, and without it runs fine with no key chip present. All online dumps seem to already be patched with the guns reversed and the key chip check taken out.
Both InitialD games use a settings file to set up some of the settings and the Sync line on the JVS card.
Patched version does not support networking for some reason.
