Bock's Birthday 2006 - one month to go...
Posted: Wed Oct 25, 2006 9:01 am
|
I thought I'd post a small reminder that Bock's birthday is 25th November, so anyone who was planning on writing a little something really ought to get started. I still have last year's demo to write, unfortunately, and approximately zero free time to do it... | |

Happy Birthday Bock! Thanks for contributing so much to the SMS community over all these years.
http://cgfm2.emuviews.com/zip/bb2k6.zip Works on a NTSC SMS 2. It has FM music but I realized apart from an emulator, no hardware has the FM chip and SMS 2 VDP. :) So just run it in MEKA! |

Wow...
Is that original music or something "copyright violated" from somewhere else? I'll try to figure out how you did it later. Is it relying on some feature of the SMS2 VDP? |

It seems like it has stretch mode enabled (224 or 240 line mode) and it also uses zoomed sprites, which is only partially supported on the SMS1 VDP. | |

Very cool, Charles. :)
Happy birthday, Bock. |

Yes, it's shamelessly ripped from an arcade game ('nettoqc' in MAME, can't remember the full name offhand) which I thought had rather well done YM2413 music. I was trying to find games from the latest date possible that still used the YM2413, in hopes that some talented composer would make decent music with it. ;) |

"Nettoh Quiz Champion (Japan)", 1995. Cool :) I can see a few YM2413 games up to 1998, though they may not have actual YM2413 music... |

Thats a weird way to say happy birthday. I have realised Bock has not replied much to this thread. He must be enjoying all those birthday presents. Charles that was an awesome demo, the music is really good to, a good choice overall. It certainly beats my attempt at happy birthday. |

Happy birthday, Bock! :-) | |

Thanks all for the thought!
Sorry I did not reply earlier, I was indeed partying and... cleaning. I've been only listening to the music and checking the demo now. "Omar what are you doing?" "I'm reverse engineering my birthday present" Took a bit to figure out why the cake's sprites were not flickering, until I noticed the zoomed sprites. It's interesting to find out that you can cover more horizontal space without flickering using them. Earlier VDP versions only support zooming on the first 32 sprites as far as I remember. Thanks Jacko and Charles for the extra effort :-) Keep in shape for March 27 competition! |

That's the spirit.
I seem to remember it only supports zooming in the first 4 sprites on any one scanline. (I can't remember if it was the first 4 by by sprite table order or x coordinate order, though.) |

There was one problem in MEKAW v0.72 that I noticed. I changed the sprite pattern generator on each scanline, to increase the vertical resolution of the sprite pixels from 2x2 to 2x1. This allowed the cake sprite to be 128x256. However on the lower ~32 scanlines of the emulated display, the effect stops working so you see chunkier looking 2x2 pixels. In an earlier version of the demo some palette raster effects near the bottom also didn't show in MEKA. Is it possible that the line interrupts are still being restricted to the first 192 lines when 224-line mode is selected? |

Yes. I can fix that if you confirm that they works properly on a NTSC SMS2. |

Well the partying part is good but cleaning, what were you thinking
No problems, I had fun in the process of creating the song, transcribing it and all. The main thing is atlest you enjoyed your birthday. |

I've attached a test program. On a NTSC SMS 2, the line interrupt occurs on all scanlines for the 192, 224, and 240-scanline display. Note for the latter I had to put the VDP in PAL mode since you can't use that mode with a NTSC monitor. Press button 1 to cycle through the display mode (combinations of M3 and M1, 0-3) and the number is displayed as a sprite on the screen. Values are: 0 - 192 line mode (both bits cleared) 1 - 240 line mode 2 - 224 line mode 3 - 192 line mode (both bits set) In MEKA, you only get line interrupts in the first 192 lines, and 240-line mode isn't supported. |

The line interrupt in 224 lines mode problem was fixed and commited to SVN.
240 lines mode is not supported because no software use that. I could add support for it, but given time, I'd rather clean the emulation code now :) |

A little OT... Is there a way to mod a European SMS1 to do NTSC? Instructions anywhere? | |
