i have been looking at Chameleon c64 one running c64 sys and one running amiga sys so i am thinking it run both one site say you link Chameleon with Minimig core but getting bit hard to work out
and on other it say zx spectrum and st can not be right as all do not have same chip or board

Chamaleon 64 runs well a Spectrum Core, and now and Atari 2600 core.

@mcbone

The Chameleon implements all these different chips in an FPGA. That's a programmable logic chip with a huge amount of logic that can be re-wired. These chips are RAM-based, so they need to be loaded on every startup. In the case of the Chameleon, this "program" (called "core") comes from flash.

We currently have:

1) The C64 core with floppy and numerous cartridges
2) Minimig core with memory expansion, harddrive and accelerator
3) Spectrum core with joystick and mass-storage
4) Pong (yes, the very early video game)
5) Pacman, Pengo, Moon Patrol (more early video games)
6) Atari 2600 with lots of games (just push a button and you get the next game)
7) Conway's game of life (hardware-based, not calculated with a CPU!)

There is no ST core. Yet

Even if the original machines use totally different chips and boards, we can implement many of them in an FPGA. In case of the C64, it means that three processors, severy peripheral chips, lots of memory and a sound chip are replaced by that single FPGA of the Chameleon.

Chameleon is an open-hardware design. You can find all the required information for core porting in the iComp Wiki: http://wiki.icomp.de/wiki/Chameleon
(including example source code and Schematics).

@Wiesel
thank you all so if you buy the chameleon and you still have to buy Minimig core to use the amiga
i f i read it right

you don't have to buy the cores - they are free for every Chameleon owner.

A core is a piece of software. If that software is open-source like Minimig is, then you "only" need to find someone who ports that code to the Chameleon. With the momentum that Chameleon has collected in the past two years, it is very likely that developers make their core available for the Chameleon, because there's so many users already. Other FPGA platforms are very short-lived, and developers are less likely to jump on those.

The "free" part is not exactly true, because the people who can port an FPGA core to a new platform have very special knowledge, which is paid well in the industry. However, if you combine the fun of having a new computer on an existing platform with the kind of money you can collect in a bounty of a popular platform, you can surely convince someone to make a new core, which then increases the value for *every* Chameleon owner.

It already worked with the Atari 2600 core: I've put out a bounty of 500,- EUR, and Peter Wendrich collected that (he even wrote a new core, because the open-source ones were not compatible enough). I might do the same for the ST core, so you can launch an ST on the Chameleon as well.

thank you i have other look at chameleon

Damn, I need to update my Chameleon when I get home. I'm missing 4-7.

@Darrin: I actually got the Atari 2600 core running, although I don't understand how to do anything but play Space Invaders, although admittedly I haven't spent that much time on it. I also haven't been able to get Minimig core working. It just hangs after a certain line on startup (the light blue screen with white text with the Dennis Van Weeren credit). While I found the latest core files to download, I was unable to find any instructions about getting it working. I have a real Minimig that appears to have died (I determined the SD Card reader appears to be dead, but that's a whole other thing). Is there any site with step by step instructions for getting Minimig core working. Are there files that are supposed to go on the SD card, and if so any specific directory? I dropped the kick.rom and minimg1.bat on to the root, but that didn't seem to work.

@Wiesel

can you create a Sinclair QL core?

@mcbone

I've got the Chameleon on my desk with the 4 way dock and it's fun to play with! So far I've loaded up the Amiga Core, A2600 Core, Pong, MoonPatrol, and Packman. The system's emulation is so good you can play two player Lemmings with two mice!

It will boot WB as well for a full Amiga Emulation. Super easy to use and fun to hack.

You'll enjoy it I'm sure.

Cheers,

Sorry, I've been busy moving house and just saw your post.

I'm at work at the moment so I can't actually check my Chameleon, but IIRC all I had to do was flash the Minimig core to the cartridge and I used exactly the same ROMs and HDF file as I use on my Minimig/FPGA Arcade.

Check your ROM file and also try a different SD card as certain brands seem to cause problems.

I won't be home for a a couple of weeks, so I can't send you the files I'm using until then.
