• musicdisk Atari STe Amiga Demo 2 by Oxygene [web]
• tft: you're right, it's a musicdisk... I missed it when I added the demo. Maybe a "pouet" admin could change it.

• mic: you're almost right. 68k only send a "tick" command at 50hz (ATARI music are 50hz). Then Z80 wake up at 50hz, and depack YM registers (all data is packed in Z80 ROM, the packed music is about 43KB). And then the magic trick is that NeoGeo has a YM2160 chip, far better than ATARI YM2149. BUT, the YM2160 has a SSG part (simple sound generator), which is hardware compatible with YM2149 :) So no software emulation, I simply put the registers into the SSG par of the YM2160

• I guess some of you will be hurt by nasty graphics of this demo, and I agree :) This is "oldskool" demo so the only goal is to have technical tricks, and no nice graphics... Here are some details about the three technical tricks used here:
  
  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. I'm sure you never hear that kind of sound on your NeoGeo :)

• ggn: to bypass the mame crc check, juste run the game from command line
  
  mame puzzledp
  
  if a rom is specify, it bypass the crc check, so it runs perfectly on mame (but the sound is less accurate than a real hardware)
