[quzar]

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

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.

thanks for the info i might start using SBI soon or start using the new Selfboot program as i am still stuck in the year 2001

Soon I will upload SBI pack, wait a while.

excellent work

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.

I put 1_stread.bin scrambled and ip.bin, and bios file "neocd.bin" (same bios wich i have used in old versions), when start the emu, and put the CDROM of a game, appear "BIOS INVALID" o_o and don't work.
