New Graphic Hardware for C64
New Graphic Hardware
Is there a interest for a new GFX Bord aka VIC 2005 ???
I allways think the C64 need an new Gfx Mode with more
Colors, Sprites and Resolutions.
if you Agree,
Drop me a line,
Thanx

If you adapt a VGA card, you will disable the VIC showing effects. Sure, a higher resolution and true-color looks nice, but this is imo not the meaning in demo coding.
If you insert blitter,use a fast core, I will call it Amiga 64. ;) |

PAL is the best solution for any low resolution and few colors system, but PAL also complicates things. if you choose VGA, you'll need a high resolution (640x400 minimum) and a good number of colors (65536 minimum) to make it look good. everything below looks just like plain shit.
now lets calculate: 640x400 with 2 bytes per pixel. on a 6502 @ 0.985 mhz with minimum 8 cycles to move a byte that makes 4 seconds to update a frame under best circumstances. make that 7-10 in reality. this still assumes that you can access a byte by simple LDA/STA...
i think anything which needs to be counted in seconds per frame and not frames per second is quite useless. |

I was wondering.
Those hacked C64DTV's, what can they add to the current C64 (demo)scene (with 256 colors and the enhancements in mind) ?

What creates the "wow" effect of seeing a cool effect on c64 is that you know about the limitations of the machine. So if you remove the limitations, you also remove the wow-effect. Maybe we should go for an even MORE limited system, to get bigger wow-effects? |

There is no way to integrate VGA in the existing circuit.
Imo it is only possible to use an adapter and transfer bytes to the external logic. It needs an own clock and CPU, the second ... it's pretty useless, a fast bitplane mode like 13h (MCGA 320x200x256) requires 64kb for one screen. ;) |

Cruzer: Wouldn't a commodore with more wow effect be the VIC-20 in that case? ;)
I was more wowed by the VIC-20 demos I've seen recently (so I've been out of the loop for a while) than any c64 demo.
As for the DTV, I think there is still wow potential there, if the new features are pushed to the limit by talented coders. |

See this for an attempt of making a VGA adaptor

that's a video (PAL/NTSC) -> VGA converter, not a new graphics card with it's own memory and all.. |

Quote: I can see dual sid cards, because hey, the sid is arguably the soul of the c64. You know, it's still uniquely c64.
I can see how a supercpu equipped c64 is cool - you can run your existing crunchers at a faster speed, it's still c64 software. But yet, the 16 bit mode of it, that just seems wrong. I dunno, tho, I'm aware people have done amazing things with it. And it's not like it's just a 68k or an arm or something, i guess.
You see, the thing is, I already have two pc's, and one of them, I picked up on the side of the road. I also have an amiga. And they have all of this neat graphics hardware already. This whole exercise of turning a c64 into an amiga or a pc, what's the point?
i totally second that. |

VIC-II + SID = C64
the cpu and stuff like cia etc are kinda replaceable. if you have VIC and SID you can achieve C64 look & feel with any cpu. |
