Hello,
it seems very interesting. Can you tell me is it possible to make a mos6502 cpu drop in replacement with this core and with a cpld?
I know, there are plenty of real 6502 cpus around, but yo…

The stack pointer hardware in the 6502 can only update the stack pointer after the stack access has happened. So, it decrements the stack pointer after pushing a value onto the stack, so that the stac…

@bobomb in case we don't get to meet this week, we should try and get some of our ideas down on this issue.
Today at lunch you mentioned you want to generalize the test setup for instructions with ze…

At least 'usb_host_KM' is broken with SDCC 4.2.0 in Debian 12. It complies under SDCC 4.0.0 in Debian 11.
Specifically:

We should be able to parse both .s -> Instruction and .o -> Instruction making the process for implementing a decompiler possible

I would like add a custom C# peripheral to my project.
So, I can add the source peripheral (cs file) on my resc file and it works but I would like build it with unit test on standalone.
It is possib…
