    Default NeoDC v2.3

    Whats to say? lots of things fixed, lots of speed gained
    Here is the readme:

    NeoDC version 2.3 for the Dreamcast by Quzar

    Changes in version 2.3:
    *Dreamcast specific
    -No longer uses SDL at all
    -Rewrote the sound driver to use spu dma
    -Sound is much faster ( less sfx are dropped )
    -New draw_fix from fox68k (thanks fox!)
    -Faster video rendering (aside from the new draw_fix)
    -Up-ported to kos 1.3 (svn 165)
    -Rearranged sound timer functions for speed
    -Prepared the source code to use FAME
    -Sped up CD-ROM file loading slightly

    *Core Emulation
    -Increased accuracy in sound chips (you will notice better PSG sounds)
    -Fixed Read Upload which fixes the crash in Breakers (and may fix more)
    -Implemented Rudimentary Bios Vector/Game Vector switching
    -Partially fixed frame counter speed
    -Added timer read and write access by the 68000

    *Misc
    -Rearranged main functions for expandability
    -Undid all the experimental things of v2.2
    -'Poked' code everywhere (many small changes)
    -A lot of source cleanup

    Download Scrambled Bin (taken down: confirmed not working)
    Download Unscrambled Bin HERE (definetly works)
    Download Source code HERE

    Compatability list for v2 on can be found HERE

    Hey peeps let me know if you got this to work cause i had a problem with it. It might have been also cause i burned it to fast or just the procedure. Also it could be scramble problems i dont know both me and quzar had the problem so no clue.

    Just use the unscrambled bin with SBInducer - put with IP.BIN & BIOS in the /Inducer/ dir and execute SBInducr's SBI2Boot option iirc ...or just use a decent scramble app.

    This might also work with Lying Wake's aka fackue's great NeoGeoCD DC Selfboot app.

    I knew you were up to something, but that's a lot you did there. Great stuff.

    Oh, BTW, it should work (the selfbooter) if all that's needed is the 512 byte (KB? I can't remeber) BIOS that's named neocd.bin and it's still in the root.

    EDIT: The "What's new" in that link above is not correct.

    Scramble it with 1st_read.bin file checker. This is definately a correctly scrambled BIN. I havn't tested it though.

    And you can use NeoCD Selfbooter to make a DiscJuggler image of it.
