NAYN by BJTS [nfo] platform :   Sharp MZ type :   8k release date : october 2011 5 2 5 popularity : 0 %   0.00 alltime top: #29764 [download] [mirrors...] added on the 2011-10-18 by branch   popularity helper increase the popularity of this prod by spreading this URL: comments NAYN NAY NAYN NAY NAY AY AY NAY AYN.   added on the 2011-10-18 22:09:36 by branch   Yes, those are software sprites on a 3,5Mhz Z80.   added on the 2011-10-18 22:10:11 by branch   terrible youtube quality   added on the 2011-10-18 22:13:00 by branch     added on the 2011-10-18 22:20:40 by g.   semmosta   added on the 2011-10-18 22:21:20 by noby   it wasn't that bad   added on the 2011-10-18 22:21:44 by svo   Quote: Sharp MZ-800 from 1985 A.D: 3.5 MHZ Z80 64KB + 16KB VRAM 16 colors bitmap (bitplanes) No hardware sprites SN76489 + beeper   added on the 2011-10-18 22:27:24 by noby   .   added on the 2011-10-19 07:15:13 by panic   nope   added on the 2011-10-19 08:30:20 by las   Rather poor attempt considering what the platform can do as far as I can tell. SN76489 is a rather capable chip, and there's a frame buffer with 16 colors...   added on the 2011-10-19 11:02:37 by Tjoppen   nyancat without rainbow is not really *nyan* :(   added on the 2011-10-19 11:16:04 by rez   Tjoppen to be exact about hardware limitations there's 64kb RAM, 16kb VideoRAM. 320x200 takes 8kb vram for each BITPLANE(like on atarist or amiga) so you get 4 colors on screen from 16 color palette. Remember you have to fill up TWO(!!!) bitplanes to have multicolor sprites. AY-3-8910 beats barely SN76489 so that tells you something about the sound quality. I DO agree that even considering the hardware limitations this isn't technicly that good of a prod.   added on the 2011-10-19 14:58:10 by branch   Glöpping hard, sorry. http://paste.servut.us/y1gt <- I think a smart z80 coder understands what's going on. After line 191 there's 'precalculated' ~addresscode that draws the wanted sprite. I guess you could store some commonly used bytesets to registers so you don't need to use eg. Quote: ld a, (hl) OR $F0 ld (hl), a but instead you could use Quote: ld a, (hl) OR B ;B=$F0 ld (hl), a rez, because it's NAYN not NYAN. NAYN != NYAN.   added on the 2011-10-19 15:16:38 by branch   Ah, I see that it's actually redrawing everything every frame. Decent blitter throughput then I suppose. It's just that I see more interesting things being possible with this. Also, don't you mean four colors per scanline? Surely careful timing allows for more colors per screen? That's what we VCS folks have to do all the time - sometimes even in the middle of scanlines :)   added on the 2011-10-19 21:49:59 by Tjoppen   Thumbing this up just because of the name. NAYN, forever!   added on the 2011-10-20 07:40:42 by MidKnight   terrible youtube quality   added on the 2011-10-20 08:26:57 by Sir   Quote: Decent blitter throughput then I suppose MZ-800 doesn't have a blitter. All done on Z80. Quote: Also, don't you mean four colors per scanline? Surely careful timing allows for more colors per screen? Haven't tried it before but I'm sure it could be done.   added on the 2011-10-20 16:24:27 by branch   нахуй   added on the 2011-10-20 22:09:17 by BiTL   Tjoppen: Everyone with brains in their head has alread upgraded their MZ800 to 32K VRAM...it's just 2 Chips you neet to put into ready sockets. 81416's or similar are not so hard to come by. Just rip apart some old PCB from trash...   added on the 2013-05-21 12:36:42 by Exin   displaying none 25 50 100 all comments (1-19) out of 19 submit changes if this prod is a fake, some info is false or the download link is broken, do not post about it in the comments, it will get lost. instead, post about it. add a comment You need to be logged in to add a comment :: register here
