![]() For it to work, you will also need to check your EMM386 declarations (if any) and make sure that region B000-B7FF is excluded, or just remove EMM386 altogether.Īccording to the documentation provided by the patch author, to start DOSBox in dual monitor mode, you must specify the -display2 parameter, followed by the color you want (white or green): dosbox.exe -display2 greenīefore the latest Windows 11 update, the color setting used to work for me. With this, the DOSBox console window has been repurposed to be the monochrome terminal (named as the secondary display) and log messages (if useful) must be retrieved from the log files. What the patch does is essentially modifying the DOSBox to report via BIOS that a Hercules card is present, and then capture writes to the B000-B7FF region (used for text on monochrome monitors), interpreting these writes and display the corresponding text onto the DOSBox console window using the pdcurses library. You can also download the complete set of files here. It was not until recently that I came across a patch for DOSBox on vogons which supports exactly this feature, and decided to give it a try. Some only support very specific Hercules + CGA combination and Hercules + VGA will not work. ![]() Not all BIOS or motherboards support this option. ![]() x use n KB for the code and data memory poolĪ Hercules card is difficult to procure, even in the early 2000s, and for years I could not get this option to work. e * use n pages of expanded memory for swapping d dual monitor mode, IDE uses other monitor Option is any of the following: (/x- = turn option x off): Srcname is any ASCII file (default extension assumed) This option can also be specified from the command line (/D), as described in the help text for TC /? (Turbo Pascal does not support BP /? or TURBO /?, although command line arguments are described in details in online help): Syntax: TC ] ] MDA/Hercules) and a Color Graphics Adapter (CGA), then enabling this option will allow the IDE to be displayed on the monochrome monitor, and the debugged program to be executed on the color monitor. If you have a dual monitor setup, specifically a Monochrome Display Adapter (e.g. You’ll see the configįile named after the version you’re running.There is an interesting option called “Dual monitor support” located in the Options > Environment > Startup dialog of Turbo Pascal 7.0 and Turbo C++ 3.01. It usually lives in your Windows user profile, typically within AppData\Local\DOSBox. I’ve used it in the past for various DOS related programs, but let’s see how it handles the CPU issue.įirst up, get it installed and then edit your main configuration file. Something people generally want to do with virtual machines.Ĭue DOSBox, a free and very well made DOS emulator. Unfortunately VMWare has no CPU cycle limiter built in, it’s just not Hemisphere, in short – there’s no frame limiter on these old 1990’s games, and they just run too damn quick. It all works great until you actually play the game and see it running as if it’s just had all the caffeine in the western ![]() ![]() You’d think VMWare would have this covered right? Not so. Old classic by installing VMWare Player, loading a Windows 98 virtual machine and installing Theme Park. If Mythbusters advice is to be taken seriously, I’ve always liked the saying “if it’s worth doing, it’s worth over-doing”, and what better way to achieve this then to try out an ![]()
