Re: DOSBox-X branch

Found a bug in INT 10h AX=101Ah that was fixed for a game. The function in DOSBox behind it reads the Attribute Controller in a way that leaves the screen blank. You'd never notice in DOSBox SVN because SVN does not correctly emulate the display blanking caused by attribute controller programming ( …

Re: DOSBox-X branch

Great! No hurries, I can wait for the next official release. Clearly if you can compile the source code from the release section, you can also git clone from the project page as well. The latest commit to master has the latest fixes and improvements. git clone https://github.com/joncampbell123/ …

Re: DOSBox-X branch

Hi, window title says "dosbox-x 0.82.22" so I'm pretty sure it's the latest version. Anyway I've downloaded again https://github.com/joncampbell123/dosbox-x/archive/dosbox-x-v0.82.22.tar.gz and I've compiled it from a clean directory and problem remains. I just realized that the byte dosbox-x …

Re: DOSBox-X branch

Hi, I think I come across some bug in the dosbox-x debugger. I want to write CF opcode (IRET instruction) in some memory address, so I put in the debugger window: SM xxxx:yyyy CF However, the byte in memory address xxxx:yyyy changes to 00 instead of CF No problem with other opcodes so far. I'm …

Re: DOSBox-X branch

Re: Illegal Unhandled Interrupt Called 6

I just updated to 0.82.22. I compiled it myself on 64bit fedora 30, as no RPM was available this time around. The situation has changed a bit. Now when I start it the following happens. On the first boot: I get the win98se boot splash screen and then suddenly on the console I see a continuous …

Re: DOSBox-X branch

Also on shutdown of Win98SE, it just hangs on the shutdown splash screen and in the log I see a continuous stream of these errors: LOG: 1367968862 ERROR CPU:Illegal Unhandled Interrupt Called 6 Are you attempting to use dynamic core? Dynamic core does not work with preemptive multitasking OSes like …

Re: DOSBox-X branch

Since you added proper MDA and MCGA, there was also Plantronics, and there is even a game now that supports it. http://www.the8bitguy.com/4032/where-is-planet-x3/ I had an ATI videocard back in the 80's that had a Plantronics mode. Other then that there was also the IBM 8514, a successor to VGA. I …

Re: Dosbox reset without close

DOSBox-X has a good example on how to do this. There's already code to exit DOSBox SVN if throwing an int(0), DOSBox-X throws an int(3) to break out of emulation and emulate a reset. This might be a good starting point: https://github.com/joncampbell123/dosbox-x/blob/master/src/hardware/memory.cpp# …

Re: DOSBox-X branch

Hey, found an issue with the FAT drive support. It affects both DOSBox-X and DOSBox SVN and it probably affects other branches as well. Writing a file and stopping at a multiple of the cluster size causes an extra cluster to be allocated. For example if the cluster size is 4096, writing 4096*N bytes …

Re: DOSBox-X branch

A problem has been identified in the built-in EGA.CPI files when locale data is loaded at boot up that puts the characters a bit too low for a game. It's possible that real MS-DOS has the same problem, and the developer of this QBasic based game didn't test against any MS-DOS installation that loads …

Re: DOSBox-X branch

OK, now I am going to play a DOS version of Spycraft: The Great Game... The game requires swapping between 3 CDs (something I have worked out how to do in DOSBox, so moving to the next question) How do I make DOSBox ask me if I want to load the disk images before starting the boot process? I mean, …

Re: DOSBox-X branch

I have a small issue, not DOSBox-X related, but I believe someone here can help. When I try to run SimCity 2000 from DOS, "C:\Games\SC2000\SC2000.exe" I get this message: "Critical Error, Microsoft compatable mouse not found. Please load mouse driver" Any ideas, please? Tks in advance. Should not …
