The state of software emulation of the SID is already amazing! I hope the efforts made in software emulation since I first started using VICE are related to what you are speaking of, mikej.

To some extent, in that the hardware analysis has already helped the software emulation.
With detailed die scans of the chip, the filters and other analogue components are understood at transistor level now. While we cannot emulate this behaviour directly in the FPGA, it is possible to model with DSP in the same way - possible better - than the software does.

Oh, which SID software emulation do you think is most accurate?

ReSid?

Yeah, the best I've heard is Alankila's floating point ReSID fork. Besides the lack of noise and screen buzzing, I don't think I would be able to tell it from a C64 better than I could tell a C64 from another.

I like the C128 but an upgraded C64 in an FPGA is more attractive to me.
Something like Jiffy Dos and Simons Basic added to it and vga output.
Has anyone here ran c64 or Amiga 500 emulation on a Raspberri Pi?

Well the Turbo Chameleon 64 http://www.syntiac.com/chameleon.html is what you say.

It still havessome rough edges but getting better all the time.  Biggest issue with an FGPA project like this is finishing it.  Although the c64 is well understood, implementing a complete 100% c64 could be a never ending project.  

So far it is very advanced and mature.  A high level of software works and most complex items work.   As noted in this thread, the SID filters are not complete but they are on a long list of items to complete.  

The good news is you can use it with a real C64 and use the SID output on that for the time being.

It is the best FPGA c64 project so far. I have tried all available FPGA c64 projects and the Chameleon is the best so far.

I have a hacked C64 DTV with a 1541 ultimate that works very well. I use the software version of jiffydos called SJLOAD for the DTV to improve transfer times on the IEC bus. I have not run into 1 game that I play that hasn't worked on the modified DTV with the ultimate. And Darrin I have used a set of those stickers on my mitsumi keyboard I picked up for the DTV, they work well.

I am glad to hear you have such good luck with your DTV!  There are also some very cool DTV only demos.  The DTV has a mode with more colours than a standard c64 as well!

Here is a link to a few programs for the DTV enhanced display.  http://dtvhacking.cbm8bit.com/common/photos/index.html

Which DTV do you have?

I have also a hacked dtv and i'm wondering what these stickers are. Would be cool to have the dtv keyboard with some c= appearance.
Are these stickers available to buy still?

I guess the Chameleon will be the one on my list for a future buy.
What is the FPGA Arcade going for these days?
I still can not buy one. :)
Also in issue 101 of Amiga Future is a case for the Mini-mig.
Who can tell me about it?
Also has SteveJ. released his Raspberri Pi case?
Later.

I think it had some kind of filter (whatever that moron Frenchshark stole from open source solutions available), but it didn't sound true to a C64 either.
I don't have MCC-216 anymore. I'm glad I got rid of that bug-ridden POS.


Do you know what the moron has to tell you, ******* ?

The filter is called a "state variable filter" and was done by myself.

Try to learn HDL before criticizing the others.

Bastard.

Maybe I don't know HDL, but I don't steal other people's work either, as YOU do. You can take your faulty hardware and you "state variable filter" and stick them though you back hole.
No one in his right mind is ever buying an MCC-216 anymore once they know how bad built the thing is and how ILLEGAL (appart from incomplete and incompatible) your Amiga core is. Not to mention the C64 core, also stolen and still having all kind of bugs.

Or the AppleII core, wich can't even load a disk image.

I hope the open source developers who you scammed with your ridiculous product will protect their work from working on your hardware so you can't steal anymore.

You are just ridiculous with your unfounded allegations based on some stuffs you have read on forums and you are constantly repeating over and over.
