I'm just wondering if the chipset itself would be legal? Like if he were to create AGA compatible FPGA replacements... ?

You can only patent implementations, if he designes his own AGA compatible chip, he does not need to worry about patents any more than the UAE people do :-)

I like the idea though :-D

You could save a lot money/headache by using Soft-core 68K CPU fitted directly inside spartan fpga. It'll be fast enough and have a lot better compatibility with old code than Coldfires are able.

IIRC there may well be one suitable at www.opencores.org

Personally, I would base the whole thing around an XScale CPU (With a 68K Jit emualtor) with a CPLD/FPGA (Whatever is cheapest) to emulate the AGA registers/features but with the GFX and audio output being directed to standard off-the-shelf video and audio parts.

We'll see how it goes.  I have to wait until I get a new job to start on the hardware (interview this Friday, here's hoping), but I might take a look at the AROS source again tonight and see just how much of a pain it will be to get a basic Amiga port going again.

AROS could take some of the sting out of the tail... I mean the OS abstracted quite a bit of the hardware away from the apps... you could use the 68k port of AROS and then run native Amiga software on that which would use off the shelf parts, Maybe with just CIA emulation at and first slowly adding more AGA functionailty to the FPGA.
