If you want to set breakpoints on memory read, you could try updating the last patch at Searching memory for values with Dosbox debugger to latest dosbox.

I suspect it may have to do with memory settings, i.e. setting video memory to write-combining. Or maybe it's timer accuracy.
Re: DOSBox Project Name Change

Seriously, I think you can't change the name so late in the game anymore (unless someone pops up and has the name licensed for his database program or similar for ages...). Then DoxBox should be called ... FireBird :pppt: If so, DOSBox Plus or DOSBox+ is better than DO$Box Pro.. :Wink: In that case …

You can try nx for X compression. Also, there's always ssh -X -C, which does deflate compression, IIRC

Arrg! Sorry, I forgot about -d parameter for cvs update. Been using svn too much lately. Sorry for the noise.

It used to make me wonder what all the fuss was about with getting Linux and whatnot working with TV cards. That's probably about TV capture cards, not cards doing TV output (which do not require any software). TV output _requires_ software. TV output is normally done by external encoders, which …

You have to redirect both stdout and stderr. Last I checked, djgpp came with a program called redir wich allowed to redirect stderr under DOS.

Uh? AFAIK Dosbox doesn't need that, here on my laptop xosview doesn't really report much CPU load when running Dosbox, for most games I care. Looking at ltrace output, it seems Dosbox is yielding at SDL_PollEvent. And I don't hear my fan often when running real mode games on Dosbox.

Which desktop environment are you using? KDE has CTRL-F? and ALT-F? mapped to many things, so most of them are not available to applications. However, they work with mouse grabbed or fullscreen, so you can try that. Alternatively, you can change dosbox's or your DE's mappings.

Indeed I bind debug pages to every page (except InitPageHandler). I use normal core, so I don't know if setting mem bps on dynamic code makes any sense (thinking about it, maybe you can catch smc). Anyway, mem bps do work, this time I have tested them. :wink: But, the break occurs at the next …

Ok, attached are memory access breakpoints for dosbox 0.65. :cool: I don't know if this works with linear memory and protected memory breakpoints. I have only tested with real mode games. I don't know if all this should be enclosed in #if C_HEAVY_DEBUG or not. If it's not being used it shouldn't …

Ok, let's see if I understand this thing correctly. IIUC, PageHandlers can be marked READABLE, which means that the host system can read memory directly from paging.tlb.read[page], and then the PageHandler must provide a method GetHostReadPt, or it doesn't have that flag, it doesn't implement the …

Thanks for the patches. The memory searching looks nice, might give a useful addition if beefed up a bit. What exactly would you like to see? Searching for bytes, words or dwords? Other things? About the break on memory reads: this doesn't work as you implemented it (note that there are only calls …

More patches, Somewhere in the forum someone mentioned he would like a breakpoint on memory read. The first patch does just that. I also have made a patch for adding cheat commands to the debugger. It's basically a breakpoint on memory change, but instead of stopping, it sets memory to a value …
Searching memory for values with Dosbox debugger
Posted on 2007-02-11, 02:20
Hi, I have patched Dosbox 0.65 so I can use the debugger to search for memory values. This only does search, which is enough for my purposes. Here's the patch:

That is windows in enhanced mode, isn't it? INT 6 and opcode 63h (c of ROM BIOS copyright string) are "breakpoints" the VMM puts on real mode code. They cause an exception that should redirect execution to the VMM (through the IDT)
