    Hi Matthias,

     

    For games that have been released using Jagtopus boards (Another World, Elansar...), I haven't been involved in the financial aspects - I gave the manufacturing company contact info to the developers, so that they could order directly. As a consequence I don't know the current prices. If you have a project, let me know so that I can get you in touch with the right persons.

    Announcement of the Atari Jaguar Europe Festival 2014

     

    The Atari Jaguar Europe Festival, "ejagfest" in short, takes place on November 15th and 16th of this year in Duisburg (near Düsseldorf), Germany. We celebrate the 25th anniversary of the Atari Lynx this year which has been released 25 years ago in 1989.

     

    The Atari Jaguar Europe Festival is an annual festival for all Atari Jaguar and Lynx fans, developers and retailers. Open-minded fans of other video game systems are welcome, too.

    The „Atari Jaguar Europe Festival is a meeting of retro gaming fans from all over Europe. The focus of attention is Atari and all consoles of the cult lable. All of you who would like to play again on systems like the Jaguar, Lynx, VCS 2600, 5200, 7800 or on a trusty homecomputer of the 80s, this is the right place.

    Retro games, homebrew announcements / presentations, prototypes believed to be lost and demos of all kind can be experienced on the ejagfest. Developers from all over Europe regularly take the opportunity to present their new developments on the festival, and sometimes even have exclusive items for sale. Another highlight was the presentation of the only working “High-res Jaguar Virtual Reality Headset” in existence, which was shown for the first time in Europe on the ejagfest in the year 2007.

    Competitions such as “Club Drive” or “Kasumi Ninja” make sure everyone has a fun time. Next to these fun competitions, the official European championship in “Checkered Flag” for the Lynx is taking place each year. To make the event complete there are retro game retailers to offer Jaguar/Lynx titles and a variety of other retro games and systems.

    USB serial ports are not visible in the BIOS, only in Windows.

     

    You should be able to use the method explained here even with current Windows versions, except :

    - MAKETRK.EXE and PADCD.COM may not run directly under Windows. You can use DOSBox to run them.

    - Windows Vista and above no longer include HyperTerminal, but you can use TeraTerm instead.

    - The USB serial port will probably have a different name (i.e. COM3 instead of COM1).

     

    I don't know if anybody actually tested it. Maybe Matthias Domin knows? I know he visits AtariAge and Jagware from time to time.

    j'ai testé les démos highres de ZeroSquare sur VJ , la première passe nickel mais la 2 eme je n'ai que + ou - la moitié de l'image

    quelqu’un a il une idée du pourquoi ? est ce un pb dans la gestion des halflines de l'emu ?

    Salut,

     

    Comme le dit SCPCD, ça doit être un bug dans VJ. En même temps, je crois que cette démo est le seul code connu qui utilise cette feature, alors bon... :P

    The USB -> serial port adapter should work.

     

    Or you can use Orion's version of Matthias' CD encryption program, which use the BJL cable. It's in the ZIP file SCPCD mentioned above, in the CDEncrypt folder. But you need a PC with a built-in parallel port for that.

    Orion_ has released a free ROM version of his "Orion_'s Jaguar Collection" cartridge:

    As I probably won't produce cartridges anymore, I'm releasing the ROM of my "Orion_'s Jaguar Collection" cartridge version for free !

     

    I guess you can flash it on a skunkboard (not tested), or play it on the Virtual Jaguar Emulator !

     

    Also, I updated the CD version to a DiscJuggler .CDI file, it will be easier to burn than the previous Nero .NRG file.

     

    Download it here : http://onorisoft.free.fr/jag/jag.htm

    The maximum amount of memory that can be mapped in the cartridge space is not 8 MB, but only 6 MB, because the upper 2 MB are reserved for things like the boot ROM, GPU/DSP RAM and hardware registers.

     

    You could have on-cart RAM, but:

    - if it's SRAM, suitable chips are probably expensive

    - if it's DRAM, you'd need a FPGA or memory controller to manage it

    - the performance will be limited because of the cartridge timings (at best 5 clock cycles per R/W access).

    - the performance will be limited because of the cartridge bus width (at best 32 bits, but that would require several SRAM chips, or a FPGA with lots of pins, plus voltage translators)

     

    Basically it's doable but not cheap, and it would be significantly slower than internal RAM.

    I don't use C on the Jaguar so I don't remember it is widely known or not, but I found one (or two ?) GPU/DSP compiler(s) while looking in old stuff tonight.

     

    The first archive is from Roine Steinberg's Jaguar Server page. There's not much info on it:

    The second archive is from the Favard brothers' web site. It contains a lot of stuff, including what appears to be Atari's port of GCC targeting the 68K, GPU and DSP:
