    Lol , you'll need the retro-tink anyways. ;D congrats again mate. Excellent to see you making you way into C64 territory. Also that UC is pretty darn awesome, congrats on picking that up too...

    Ohh, how interesting! You'll have to let us know how good that component FPGA VIC-II solution is...

    Will do, prob a week or so before I receive it.

    That newly developed FPGA VICII that you were talking about sounds really cool, but I've been trying to find info on its sprite capabilities and I am finding jack all.. are there any changes to the hardware sprites limitations? If they increased this to 16 (dubbble of the original) or so on the screen at the same time I'll be all over this quicker than a rat up a drain pipe. .

    Sprite limitations were overcome years ago on the existing VIC-II, by chasing the raster line up to 100 sprites are possible on the screen at once via sprite multiplexing.

    What's exciting about the VIC-II Kawari, apart from the hardware accelerated 80 columns as it's own mode, is the 32k (possibly to be 64k) memory dedicated to the VIC-II itself - That's effectively chip ram for the VIC-II that allows for any number of possibilities including increasing the speed of the C64 overall due to less CPU halting as the VIC-II takes bus priority. Then you have the increased color palette, although, once again, the limitations of 16 colors were overcome years ago (not that it was really a limitation when you consider that all 16 colors could be displayed on the screen at once in high resolution mode).

    Here's something else really cool, I can't remember if I posted this yet or not. 50fps 16 color video with audio using the C64's previously underutilized Ultimax mode. This is the mode the 1541 UII+ exploits:

    wow, amazing little video, i really enjoyed that!!! thx.. even more amazing when you think thats running on the c64..

    can i do sprite multiplexing in basic? :D

    If you had have told me when I was a kid that my C64 would be capable of such feats, I would have looked at you sideways.

    As for Basic, I haven't used Basic ever since I ported a simple Basic program poking addresses to change the screen and border colours in succession and realised that assembly language was literally 200x faster!

    When you really get into it, the C64 really did have interesting architecture - There's a reason why it was so popular with coders/developers. In comparison my 600XL is amazing considering the age of its architecture, but it's obvious the C64 is the younger design.

    Commodore effectively used the Apple II's interleaved bus design with Atari's DMA graphics, but only on demand when really needed - Clock for clock, with the screen enabled, the C64 is a vastly more efficient design than the A8. Especially with the C64's color memory.

    Definitely cool..
    Bought a Kung Fu Flash cart for my other 128. It's a neater solution than having the sd2iec hanging out the back.

    It's a PAL model, so should be zero issues. I am rather curious about the FPGA RGB output on that other c64.. it has a switch for line dubbling, so should be pretty stable picture.. is there any loss in going from RGB to VGA?

    My SD2IEC is really neat. If you have a look at the pics/vids of my system you should see it, it's the white cart like box with the SD card in the top plugged directly into the IEC port. It even has passthrough, not that it works too well in relation to passthrough as it's open drain so a real 1541 creates all sorts of havoc with it's pull up resistors.

    Yeah that's pretty darn neat, much neater than mine. Mine looks like a mini 1541..

    Edit: Sorry to drag up your old post, was just looking for a good pic of your setup.

    Yeah, I'm not a fan of those mini 1541 looking devices. I'd prefer one made to look like the CMD-HD, as that's essentially what it emulates.
