Hi Folks

This is the first NEO-GEO demo by Oxygene!

Note: This demo runs on real hardware: MVS cartridge or NeoGeo CD
      (Thanks to Furrtek for testing it on real hardware)

This package contains both ISO file for NeoGeoCD version, and
classic ROM files to run on emulator or flash on real hardware.

Technical details:
This demo features three technical tricks:

1) A big spinning filled vector cube. NeoGeo can't do software rasterizer
   because graphics are only made of tiles, located in ROM (CPU can't modify
   tiles bitmap)
 
2) The color bars are disting in Y axis, so it required sprites. There is 32
   bars of 20 sprites each (NeoGeo sprite is ALWAYS 16 pixels width) wich
   means 640 sprites! But Neogeo only support 384 sprites!
   
3) During the demo you're listening an ATARI-ST music! It's a ST-Sound YM music,
   my own ATARI sound emulator
