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

You don't get the syntactic sugar and raster IRQ line/VIC bank, but otherwise it's pretty much the same. |

While I can read VICE's io output too, I wouldn't go as far as calling it the same. It's not just syntactic sugar, it saves time and leaves less room for making mistakes... |

Just patched vice-2.2/src/monitor/monitor.c to display this:
** Monitor 000 001
(C:$e5d4) io
Display Mode: Standard Text
GFX Mode: hires color
VIC Memory Bank: $0000 - $3fff
Video Memory: $0400
Character Set: $d000
Bitmap Memory: $0000
VIC-II:
>C:d000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................
>C:d010 00 1b 00 00 00 00 c8 00 15 71 f0 00 00 00 00 00 .........q......
>C:d020 fe f6 f1 f2 f3 f4 f0 f1 f2 f3 f4 f5 f6 f7 fc ...............
Could be enhanced easyly of course:
if (mem_ioreg_list_base) {
while (1) {
if (n==0)
{
v_d016 = mon_get_mem_val(default_memspace,0xd016);
v_d011 = mon_get_mem_val(default_memspace,0xd011);
v_dd00 = mon_get_mem_val(default_memspace,0xdd00);
v_d018 = mon_get_mem_val(default_memspace,0xd018);
v_bmflag = ((v_d011&0x20)>>5); /* 0 text, 1 gfx */
v_hmflag = (v_d016&0x10)>>4; /* 0 hires, 1 multi */
v_bank = 0xc000 - (v_dd00 & 3) * 0x4000;
v_bitmap = ((v_d018 >> 3) & 1) * 0x2000 + v_bank;
v_map = (v_d018 >> 4) * 0x0400 + v_bank;
v_font = ((v_d018 >> 1) & 0x7)*0x800 + v_bank;
/* $1000 and $9000 mapped to $d000 */
if ((v_font==0x1000)||(v_font==0x9000)) v_font=0xd000;
if (v_bmflag) mon_out("Display Mode: Bitmap gfx\n");
else mon_out("Display Mode: Standard Text\n");
if (v_hmflag) mon_out("GFX Mode: multi color\n");
else mon_out("GFX Mode: hires color\n");
mon_out("VIC Memory Bank: $%04x - $%04x\n",v_bank,v_bank+0x3fff);
mon_out("Video Memory: $%04x\n",v_map);
if (!v_bmflag) mon_out("Character Set: $%04x\n",v_font);
mon_out("Bitmap Memory: $%04x\n\n",v_bitmap);
}
Edit: I assume this to fuck up all monitors except for x64. |

What would really rock would be a command to display the internal state of the chipset, and not just its external registers. It'd be a huge help for coding VIC tricks, and the SID would show something more interesting than zeros... |

Magervalp is right. It is precisely those thingsthose that would not be possible on C64that make a emulator monitor especially valuable in some cases. In a similar vein, one cannot really check the status of the SID at a particular moment, as it works right now. I think it only shows the last value written to any SID register for all registers (just like the real SID works, when seen from the "outside"). |

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 |
