Question re Altirra Debugger

[Heaven/TQA]

I was just wondering for weeks now how can I disassemble memory location and then simply disassemble next page?

 

on most debuggers I am doing stuff like D 4000 and then a simple D while the next page is displayed. and in Altirra?

[flashjazzcat]

Scroll wheel works for me - just pull it down and it keeps disassembling.

U

 

Seriously.. U 4000

 

Better using the windows for this stuff, then you can just page up and down through memory..

[Heaven/TQA]

aem... no?

u 4000 gives me one page, then hitting page down, cursor down no effect?

[andym00]

Debug->window->disassembly..

[flashjazzcat]

I'd assumed you were using the disassembly window.

[Heaven/TQA]

aehm.... no... oldschool command line? or what are you guys using most?

[Heaven/TQA]

ok. disassemly windows works but is there a way to show only the mnemonics without the memory dump? ok not a big deal but could help in copy/pase code.

[andym00]

Not that I know of.. But surely whatever editor you're using allows you to do a rectangular select ?

In VisualStudio it's shift+alt to select a rectangular region..

[Heaven/TQA]

and another question compared with Atari800 debugger... save state? how? the quickstate is not saveable for later?

[flashjazzcat]

Personally I'd like to see the windowed memory dump scroll like the disassembly window, but preferably up and down.

my editor is notepad

You can copy from the Dissasembly window (as well as probably most others).

I often do traceblits with breakpoints, grab a couple of frames worth of trace and copy out the lot.

 

Select the block of text and use CTRL-C

 

Agreed, there's certain commands that need to continue their listing if you just enter them without parameters.

Memory window scrolling would be nice, but I keep four memory windows open, each doing 256 bytes in size, so mostly that's enough for me..

As for Heaven and his editor.. Get a new editor

[Heaven/TQA]

any ideas regarding save state?

[andym00]

I've never used it in Altirra, and not quite sure what you're asking about actually

[andym00]

Oh, I see, I think.. In the debugger you can't do a quick savestate because "it's in the middle of an instruction"..

[Heaven/TQA]

Well... Save States help when you have a special condition to test... Or in a game to avoid the play through of levels. Atari800win can load save states.

[Creature XL]

Savestates never worked for me. Neither from debugger nor when just running the debugee. But I did not try for long. Would be interested if you succeed.

[phaeron]

I never bothered to implement continuations for the disassembly command out of laziness. The .dumpdsm command will dump a disassembly to disk, and in 2.10 test-13 it has been expanded to support options that allow you to turn off code bytes, EA decoding, etc.

 

Current versions don't allow you to save states to a file because the file format isn't stable enough yet. The emulator stopping in the middle of an instruction is one of the factors that complicates this.
