  1. I don't have linux nor any idea of how to port the zerosquare's routines on linux ^^

    it seems that it doesn't work on win98, does any one can test it and tell me if it's working for him ? (on xp or 98 ?)

    because if the pack only work on my computer, that's a bit useless :/

     

  2. Hello there !

     

    I just got a JagCD from someone and the first think I tried to do was trying to encrypt a CD using the BJL version of Matthias Domin Encryption program.

    But this need a serial cable that you plug in the dsp port and this need a jaglink, and I don't have this hardware.

     

    So I tried to save some money and soldering pain, and used the "mini debugger" source of Zerosquare that allowed me to dump the Jaguar memory to a file on my PC. I then patched the program of matthias to disable uart and xmodem transfer, as well as joypad reading that was disturbing BJL transfer, and added the BJL transfer routines from Zerosquare instead of the uart/xmodem routines.

     

    and here is the result, a really easy to use "one-double-click-encryption" pack

    which allow you to encrypt a cd using your jagcd and the BJL only just by double clicking on a batch file that does the job for you.

     

    I would like to thanks Zerosquare and Matthias Domin for their great job that allowed me to do this pack.

     

    Enjoy !

    ps: This works only with a parallel port at $378, on XP or 98

  3. I was playing a bit with the blitter today and I tried to do a line routine using the blitter (in 68k, but just for blitter-understanding purpose)

    and I came up with this nice little screen that can be used as a screensaver ;)

    200 lines, redrawn each time (the VBL is almost full :D but the code is over-VBL-jump proof so it will only be slower in 60Hz I suppose)

  4. Do you emulate the GPU pipeline also?

    read the readme ;)

    I don't emulate that, because it would be a bit complicated to represent in the debugger, plus, the debugging process would be fastidious and a bit strange if it was following the exact pipeline.

     

    About division, how do you emulate 16.16 division?

    What is a 16.16 division?

    Do you also emulate that the G_REMAIN does not

    necessary contain the remainder but a value

    that permits to compute the remainder?

    I don't emulate any of that for the moment :)
