I don't know about other languages, but the French translation on the back of most Jag boxes is so full of mistakes it's hilarious. Not very classy considering it's one of the things you look at when you buy a game

Are you using a separate S-video input, or trying to use the SCART socket ? (you can't have both S-video and Composite/RGB together on the same SCART plug ; it's either one or the other). Check that the chrominance signal (and its ground) is proprerly connected (it sometimes does this if it's not). Also check if you are using the luminance and chrominance signals, and not the composite video signal by mistake.

Yes, most male-male SCART cables are indeed built that way (this is true for composite video and audio ; R, G and B signals are pin-to-pin since there is only one set of pins).

At least composite video should work. Since there are only two wires (signal and ground), very little can go wrong. Have you connected the ground properly ? No idea about the JagCD as I don't have one. It doesn't seem normal, though.

No resistors or capacitor are needed. Have you checked your cable with a multimeter ? It looks like you have a broken wire or a bad connection.

Wouldn't it be possible to release the code without the game data, together with a program which would extract the data from game files provided by the user to build a cartridge image ? That way, people who own a copy of Doom 2 could legally play it, while others could play the levels from the freely available demo. DOOM (and other games) ports on other machines use this strategy, and I don't think there are legal problems in this case.

Yes.

Here's the link : Atari Jaguar A/V S-Video cables

Here's the pinout used on the official SCART cables (which support both RGB and composite video). I figured it out using a multimeter. Jaguar pin <-> SCART pin ------------------------ 9B <-> shield 6A <-> 16 11A <-> 8 4B <-> 15 3B <-> 13 7A <-> 11 7B <-> 9 5A <-> 7 4A <-> 5 11B <-> 20 10B <-> 18 1A <-> 6 1B <-> 2 2A and 2B <-> 4

No problem, you can have all the different output signals on the same cable. The composite sync should be connected in parallel with either the composite video output, or to the S-video luminance output. I recommend using the composite video output, as that way you'll get a SCART output that supports both RGB and composite. The Jaguar outputs sound independently of how the video signals are connected, but some TVs mute the sound if they don't detect a valid video signal.

One way to build the cable easily is to reuse a VGA extension cable (a cheap and thin one with individual wires, not a thick one with coax inside). But beware that some of them have missing or unconnected pins.

Yup, with that you should be all set. Let me know when you've built the cable

According to the documentation, it doesn't look like the software even supports dumping the existing contents of the cartridge, it seems like it can only reprogram it. Back to square one... I did write some software which can be used to dump cartridges a while ago, although it's not the primary function. It uses the BJL cable to communicate with the Jaguar, but I could probably modify it to use the Jaglink instead. At this point you have two options : - buy or build a BJL cable - build a serial cable which connect to the JagLink (also used to encrypt CDs)

I was thinking about tools used for dumping standard cartridges, but you're right, since it's a flash cart using the original software is the most logical way There is some info about the flash cart software in this topic. Be careful in what you do ; you don't want to erase it by mistake instead of dumping it

Great. You will also need either : - a BJL cable and a PC with a parallel port (either on the motherboard or on a PCI-(E)/PCMCIA/ExpressCard board -- USB adapters won't work), or - a JagLink/(s)catbox or similar device, and a PC with a serial port (either integrated, on a PCI-(E)/PCMCIA/ExpressCard board, or an USB adapter : any of those will work) Do you have that ?

Do you have a Jaguar with a BJL ROM in it, or a JagCD ? One of those will be needed to dump your cartridge.

Great ! Now that you've warmed up, what about Doom 3 ? Just kidding Good job

Thanks guys, it's great to know we have supporters Be assured that we're as eager as you are to complete it

Thanks to Reboot you'll be able to make your own

Interesting info, as always with Curt. Thanks for making it available !

I'm not sure, but I vaguely recall Curt saying something like those earlier documents where later found to be incorrect. And Atari didn't mind releasing grossly inflated technical specs. They did with the Panther and the Jaguar (remember those "850 millions pixels per second" talks ).

If your TV has a manual setting, try to adjust the tuning up and down to see if there is a position where you get a clear sound (the picture will probably be very distorted). If it's the case, this is not a problem with your Jaguar, it means that the RF standard isn't the one your TV is expecting (there several different and incompatible versions). A composite, S-video or RGB cable will fix the problem.

Here's a picture of the auction text since it will eventually disappear :

This is a bit undeserved. As far as I can remember, rotary support in Tempest 2000 is an undocumented feature
