Are you sure that there are no short-cut between two wires of the Boot ROM ? Normaly, only : 1-30-31-32 pins are short-cut (VCC)

Hello ! You can find an redrawing of the Jaguar Alimentation circuitry here : http://scpcd.free.fr/images/jaguar/alimentation.jpg (* : not present on the Jaguar) (** : is a short cut on the Jag) The coil near the MC34163DW is L28 : 220uH. Where had you short cut the 9V with the synchro on the board ? Regards, SCPCD.

I don't know if I have understood correctly but you have connect the switch 50/60Hz on R19 ? Because, if you would like to use PAL, you should take up the R140 :http://www.mdgames.de/jag_eng.htm to configure correctly the Video time base generator by the jag os.

Hi ! There are many differences between a NTSC Jag and a PAL Jag : - the resistor that you replace by the switch - the frequence (very very little difference) - RCs oscillators to filtering the video output for the S-video and Composite signal - and an another resistor to switch the MC13077 in NTSC or PAL mode. I think that to switch the Jag in a more 'real' PAL system, you should take up the R19 resistor of 000 (or 0R) connect to the pin 19 of the MC13077DW (this resistor is only in NTSC system) but this modification affect only S-Video and Composite video output. The RGB output is not affect by this modification. (the RGB output is generated by TOM) Regards, SCPCD

Hi ! The filesystem will be the FAT32. All informations on how to use the CF will be available when the card will be 100% finished Regards, SCPCD.

Why 100,000 for cartridge and JagVLM? Because of the use of the same EEpROM : the 93C46 If you read the datasheet of this component, the manufacturer say that this memory could be written 100,000 times. And this number is generaly the same for Flash and EEpROM and it is realistic. And this memory type maintain very long time data. Regards, SCPCD

Hi ! I see the password unlock process as you say : the Jaguar CF reader after boot check and unlock the CF card and if it's good, launch the CF program. You have a very good idea with the fact to made the encryption on the Jaguar CF reader !! I have before the problem with how simplify the encryption with minimal distribution of the encryption process.... Now it's resolved. Thanks ! I will try password protection as soon as possible. For the question of the saving area, it's possible with the use of the integrated filsystem (stockage in the hybride filesystem area or the FAT filesystem area). I think that the use of an special area is not necessary because of the no very important use of speed for read saved data. The use of the filesystem for saved data is better because you could made more saved profile with an minimum constraint. And also prevent write error (bad sector it's possible because a CF is after all an Flash architecture ! so 10000 to 100000 writes cycles depend of the CF quality) Regards, SCPCD.

The CF cartridge has approximately the same size that original Jaguar cartridge. (only 5mm more)

Hi ! The CF has an integreted system with password. So if you protect your CF with a password, you couldn't read data if you don't give the good password after each power on. Not actually tested but test as soon as possible. We will made also an encryption algorithm to protect datas and generate the password. So, the CF is best to protect data than CDs or Cartridge. The prototype in photo work very well. You can see a socket for a ROM that would contain all for read the CF. We will made all features to use two possibilities : - an hybride filesytem optimized for very high speed transfert - the possibility to use FAT16 The access times are not actually available because of tests, soft debugging and optimisations. Regards. SCPCD.

It's very strange... I don't understand the exact way of the 'reds blink and blues blink' terms. (I'm French) But : First, as paolo, I have think that it was the TV set who bug with the Video synchro of the Jag (I have already this problem with an very bad quality TV) but if you have try with another... Else, the video area is in the left of the GPU when the 68000 is on the bottom. The capacitor for the red is : C14 1uF 50V green is : C17 1uF 50V blue is : C18 1uF 50V But I think that it's more a sync pb. Have you try an SCART cable (if you can)? If it's work it's the circuit for the MC13077DW who bug... (a capa or one of the oscillator) I'll search in the Jag schematic to find where the pb could come. Regards. SCPCD.

Hello ! My favourites games in my collection : Alien vs Predator DOOM Wolfenstein 3D Rayman Iron Soldier Iron Soldier2 (CD) Battlemorph (CD) Blue Lightning (CD) Hover Strike: Unconquered Lands (CD) Kasumi Ninja Super BurnOut Tempest 2000 Vid Grid (CD) and my TOP Game : ZERO 5 !! Regards. SCPCD.

Hello ! The robot motherboard is not a Jag :-( but an PC take on board : PIII 733MHz with 256Mo SDRAM and Linux BlueCat. The robot has 2 webcams to see the game's flat and recognize differents elements like cylinders, box and spheres. The robot control motor is based on a Cyclone FPGA. LEDs on this board are used to debug the card (for the angle, position X,Y, and speed) There are also a Bus card to multiplex the serial communication of the motherboard to other cards (with the MAX7000).

Hello, I have made modification on my OS so the memory management is better and faster. Since end february, I work for the robot because, the first robotic cup is the 23 April and after it is the 4 to 7 May. I would like to make benchmark of the AI before the end of this week. The development of the OS would restart after the French Robotic Cup. Regards. SCPCD. (robot's Photos are available on :http://scpcd.free.fr/gallery)

Hello, It's possible to write an another color when the bit is 0 !!! But it works only in >= 8bits/pixel. So, to made the write when the bit is 0 you must write the colour in the B_DSTD register like the colour in the B_PATD register. Then, select the bit BKGWREN of the B_CMD register. Why doesn't it work in lower resolution ? Because to write in lower resolution you must use the DSTEN bit of the B_CMD register and with this option, the B_DSTD is not use. Regards, SCPCD

To made pdf I use the printer emulator : 'pdfcreator'. It works fine. http://sourceforge.net/projects/pdfcreator SCPCD

Symmetry of TNG wrote in the blitter post : Now that I have translate my work I can reveal it in this forum. I work on a new jaguar development kit !!!! The prototype is in development and it is composed by : 1 ROM with OS 1 main card to plugg in the Jaguar cartridge port with many features 1 expansion card (thanks to Matthias for his help) More informations in my web page (look after Jaguar Evolution 2) http://scpcd.free.fr/us/jaguar/Jaguar.htm Regards SCPCD.

Hi ! I have made tests with the bit2pixel expansion and it is possible to made : 1bit/pixel -> 1bit/pixel 1bit/pixel -> 2bits/pixel 1bit/pixel -> 4bit/pixel 1bit/pixel -> 8bits/pixel 1bit/pixel -> 16bit/pixel 1bit/pixel -> 32bits/pixel I explain it in a manual that I started to made to regroup many features that Jaguar's developers found. Actualy, there is only the bit2pixel expansion but in the futur, I'll expend the manual. http://scpcd.free.fr/downloads/fichiers/JETRM.pdf Regards SCPCD.

Hi ! Next the code translate in English. regards. SCPCD blitter2_e.zip

Oups ! I forget to explain how it works Thanks to Matthias for add this. regards. SCPCD

I found it !!!!!! I don't know if it is the best method but it works fine. In fact, it is explained in the technical documentation of Tom et Jerry but it is scattered. So I made an example to download (it is a patched old code but operate) http://scpcd.free.fr/downloads/BLITTER.zip SCPCD.

Thanks for your answer. I'll try it this week-end. I would like to use this feature to write characters into objects of 16bits to have the maximum speed. Regards. SCPCD

Hello ! I would like to use the bit to pixel expansion mode of the blitter but I don't find the configuration to made for this. I would like to have a color when the original bit is 0 and an another color when the bit is 1. (with the possibility to change colors) Nobody know how could I made this ? regards, SCPCD.

HI ! Tanks for all your help ! If I found the time maybe I would convert the robot code for the Jaguar :wink: So, it would be possible to made a Jaguar robot as the Sony's AIBO Regards. SCPCD

In fact, it's not for the Jaguar, it's for a video processing for the robot of this year. (I'm in the robotic club of my school) I have made test with many video format for video processing and it seems that it is easier to look for object in the screen with the cry format. Thanks to ctsnlc for the table. Regards. SCPCD.
