NeoDC v2.3

Post by Quzar » Sun Apr 10, 2005 7:13 am

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

i figured, my scrambling tools dont seem to work properly. if anyone could post/host a scrambled bin that they know works (based off my unscrambled bin) that would be nice.

burn it and load with dchakker or demo menu. Or you can scramble it and selfboot it. The first is easier.

Good job bringing NeoDC so close to completion, Quzar. I'm glad to see you've got the svn KOS up and running, lots of new stuff for you to play with.

law56k, the file is unscrambled, you need to scramble it before selfbooting (?)
