Any 65816 plans?

[Mark Watson scrameta-gM/[e-mail] [chameleon_64]]

There are lots of Atari 8 bit accelerators using the 65816. I believe this
is also the case on the C64.

There is not, to my knowledge, any half decent 65816 vhdl or verilog core.

Has there been any work on a 65816 for this project?

It's on my todo list but somewhere in late 2015 at the rate I'm going...

We've discussed it a number of times internally, but came to the
conclusion that it's not worth it. Almost every accelerator for the C64
used that processor, and almost every accelerator failed to set a
standard for the masses. They essentially did what we always wanted to
avoid: Create a new platform.

The C64 has a unique property in being compatible to millions of units
out there. Even today, the accepted standard is "C64 with floppy drive"
as a target for new software developments. Of course we've seen a demo
coming out for REU and a game written for SCPU, but those are minor
releases compared to what's being developed and what's already available
for the standard platform.

We have a huge number of bugs to fix for the Chameleon core. If those
are fixed, there may be a reason to look for something new to develop,
so it's not completely excluded. If you deliver a 65816 core and a test
suite, I'm more than happy to pay for implementing it into an SCPU core.
If you choose LGPL or an affordable commercial license, that is ;-)

ciao,

Thanks Jens. Understand concerns re creating new platform. I wanted to keep
the a8 core 'vanilla' similarly. Though couldn't resist a couple of bits to
increase video chip clock!
I want to write a CPU at some point, so might tackle this eventually.
Probably not for a long time though!
