Maybe fixed again. (or something else gets broken)

2) in debugger (with a machine with 8MB z2 memory) if you type
s "something"
the response is bad:
This goes to category "unsupported". May or may not be fixed someday..

3) in machines with cache enabled if you use the 'a' command in debugger the code inserted is unusable if memory location used is in some cache
yes, I know, this is some sort of self modify code, but we need an escape:
a new command in debugger to flush cache (i've tried setting CACR manually but do not works) or simply auto-flush after last 'a' instruction inserted
It isn't that simple. 68020+ has long prefetch, it needs reload too if you modify instruction close to current PC and that can't be automatic. (or timing would change each time debugger is exited)

I haven't yet decided how to handle this. Toggleable automatic mode sounds nice but it may be too annoying to implement..

4) 'fs' command do not work for me (it may be that I do not use it well..)
from help:
Code:
fs <lines to wait> | <vpos> <hpos> Wait n scanlines/position.
fs n scanline wait works, a defined position don't.
Perhaps it works better now but note that it can't be accurate if CPU is blocked, it needs to wait until CPU gets clock cycles.
