I still need help with this. See my above post for the problem I'm having now.

Still having a problem. It's still not reading the disk. DOSBox debugger reports this error "BIOS:Disk 0 is not active". To create the boot disk that has the program (first sector boot program) I'm running, I've compiled assembly code using NASM in raw mode. I boot the boot disk in DOS Box by …

You might have made a typo in your ASM. it is int 0x13 you are probably calling int 13 which is 0xd in hex. Wow. That was a real noob mistake for me to make. I could have sworn that the web page I was using for a reference to x86 interupts said that it was interupt 13 decimal, but upon rechecking …
Possible bug in DosBox
Posted on 2016-06-04, 16:24
It seems to have a problem with interrupt 13, which is direct disk access. I'm trying to create my own program that runs at boot-up. I'm testing it in DosBox by using DosBox's boot command to boot the disk image that contains this program (which I've written in assembly language, using NASM). One of …
Re: Feature suggestion, Let 4:3 aspect ratio work in ALL modes
Posted on 2016-02-15, 00:14
Text modes are aspect-corrected in SVN. I just tested it now, and I see that it does now work in text modes. However, I also notice that in order to do so it has to duplicate some lines, and it does so with pure duplication of the lines. This makes some of the letters look glitchy. Maybe you guys …

Feature suggestion, Let 4:3 aspect ratio work in ALL modes
Posted on 2016-02-13, 22:59
Currently it only works in graphics modes, not text modes, but I want it to work in text mode too. Remember, ALL monitors that existed back in the old days, when DOS was THE operating system, were CRT monitors, and they all had a 4:3 aspect ratio. The result is that all video modes (both text and …

Yeah, I'm not far from closing this thread, since obnoxious entitlement, not reading whatever is posted, not answering seems to be a big thing for vg555 (or I'm on the ignore setting). I'm not ignoring anything. However it appears that the developers of DosBox are in fact ignoring the serial mouse …
Re: How do I swap floppies in DosBox

Would it really be that hard for them to include these features in the main version of DosBox? It would indeed be rather surprising if the floppy-image swapping is not included in the next official version of DOSBox, especially since it is in the official SVN (rather than some extraneous patch that …

There's probably many more such features like this that absolutely should be added, but for some reason (one which I can't imagine) the official developers of DosBox have chosen not to add these fatures. All I can do is beg, and hope that they eventually decide to add them. The #1 goal is …

Re: Dosbox 0.74 is broken regarding one particular game

the DosBox console/status window will show "Exit to error: DMA segbound wrapping (read)" as the last entry when the game locks up. That's the clue to fix the problem - you can use the SVN version of DOSBox, and set the ems=emm386. It avoids the bug in emm386 that is causing the lock-up. For DOSBox …

The problem with SVNs is that they are nothing more than mods. There's DOZENS of them out there. No, there are certainly not DOZENS of them – unless you count outdated versions, but in that case you could just as easily say there are dozens of official versions of DOSBox. Pretty much all you need …

1st of all no links to abandonware sites (I'll fix that) Also did you try SVN of Dosbox? Also, the different versions of Dosbox can live on the same system as long as you use different folders. The hassle of using different versions is not more than two mouse clicks. The game was made in South …

Time to build a Retro DOS Gaming PC :) That's how my "journey" started. There were a few little things that I noticed about DOSBox, and that made me get into real hardware. Nope. If it's ridiculous to have to download a separate version of DosBox dedicated to playing each game, then it's CERTAINLY …

The problem with SVNs is that they are nothing more than mods. There's DOZENS of them out there. Each one has very specific features that are not shared with other ones. So if I need one feature to play one game, and another feature to play another game, then I find myself installing a dozen …
Dosbox 0.74 is broken regarding one particular game

The game is called Vanslug: X Mission. I noticed when I played it in Dos Box, that after defeating the first enemy (or any enemy for that matter), the game immediately locks up. I notice it does this only when sound effects are enabled. Music being set to Midi, Adlib, or Off has no effect. Only …
Re: Some of your video modes are incorrect.
Posted on 2015-03-28, 00:12
They're definitely color modes, but note that they are planar, so what color planes are you enabling/selecting before writing to video memory? What do you mean enabling? Isn't each plane enabled on a per-pixel basis, based on the data that you feed to them? And don't all the planes have to fit …
