this macro can't handle zero flag correctly now.
test case:
when cary flag is cleared and register value is 0x01, it fails to set zero flag.

fix code:

.macro do_ror_inner reg
        setflags_pre
        it cs
        orrcs   \reg, #0x100
        tst     \reg, #0x1
        it ne
        orrne   \reg, #0x200
        bic     \reg, #0x1          @ clear bit 1 !!!!!
        lsls	\reg, #23
        setflags_post
        lsr	\reg, #24
.endm

I've loaded the a6502.bin file into a Discovery board, and it enumerates on USB and outputs the following:

Hi
 00  00  00  00  00  00  00  00
Go:  fdd3

According to the docs, it's starting Supermon64, although based on some Googling, the Supermon64 prompt should be a '.'. I've tried various commands, with only 'g' and 'x' doing anything. I'm guessing that 'g' should be 'go', but don't know how to set the address. 'x' is dumping memory from 0x0000..0x007f.

Would it be possible to indicate what commands are supported, or a link? If it's running Supermon64, I did find this article.

(I did see the link to Chris Baird's stm6502 project, but that link is now dead)

Thanks!
