Vice Monitor

Howdy all,

I've been toying with some vic timing tricks and I've read that when entering the monitor from vice, that I should see the current raster line and cycle.

I only ever get LIN 000 and CYC 000.

I'm using winvice 2.2, but I've also tried with winvice 2.1 with the same results.

Anyone have any advice?

Cheers

Voltage

This just proofs that the io command in VICE is utterly useless. Even for the VIC, I'd want to see both the read and the write state of $d012. Or for timers of a CIA. Currently it's far from useful.

Enthusi: cheers, would be nice. But beware of the check for $1000/$9000, also $1800/$9800 should see $d800. Also, machine type can be checked.

i have added the needed mechanisms to dump states of any io devices.... try "io d000" in recent trunk, it will give output very similar to what mr.sid suggested :) (and ofcourse its now easily possible to extend and to add whatever fancy info from the internal structures)

the above posted patch is not complete obviously.
You will have to declare v_bank etc. first.
And the bitmap address need not be displayed in text-mode, etc...
But I guess if someone adds a "are we in c64-mode?"-check it could be formed into a real patch.

Nice, Groepaz! I've applied this change and it works for me

too bad it has to be duplicated in viciinew\ aswell
