![]() ![]() You can't scale the window when output=surface, so experiment with settings like these: windowresolution=1280 x 1024 First, ALT-ENTER will toggle DOSBox into full screen mode, although when you return to Windows your windows may find themselves resized.įor Windowed mode, I used these settings. ![]() There's a few things to you can do about it. Note that DOSBox will start up TINY if you have a 4k monitor. Type "intro special" for a full hotkey list. DOSBox’s CPU speed is displayed in its title bar. You can speed up games by pressing Ctrl-F12. If a game runs too fast, you can slow it down by pressing Ctrl-F11. It emulates classic hardware like Sound Blaster cards and older graphics standards like VGA/VESA. DOSBox is an x86 and DOS Emulator - not a virtual machine. It's a MASSIVE 23 megabytes of content!ĭOSBox has ben providing joy in its reliable service for over 16 years and you should go check it out RIGHT NOW, if only to remind yourself of how good we have it now. I had the CD-ROM Collector's edition with all the audio from the original actors, not just the floppy version with subtitles. One gaame was " Star Trek: Judgment Rites" from 1995. I was over at my parents' house for the Christmas Holiday and my mom pulled out a bunch of old discs and software from 20+ years ago. Probably similar to the above, but gives a black screen, does respond to commands like "exit", and can switch to windowed mode with key combination (F12-F).I blogged about DOSBox five years ago! Apparently I get nostalgic around this time of year when I've got some downtime. set output=opengl -set fullscreen=true -set aspect=true This screenshot is with output=openglnb on a 2K monitor with AMD graphics:īehaves the same when started in windowed mode and switching to fullscreen. Same with openglnb, openglhq and openglpp Can switch to windowed mode just fine with key combination. Showing perhaps just the first row and the first few characters in a fullscreen. Super zoomed in view of the top-left corner of the dosbox-x window (blue background with border lines). ![]() Starting DOSBox-X with SDL_VIDEODRIVER=wayland. But starting in fullscreen results in a similar white flash, followed by a black screen and an almost immediate segfault with a core dump.ĭosbox-x: output_surface_sdl2.cpp:187: Bitu OUTPUT_SURFACE_SetSize(): Assertion `sdl.surface->w >= (+)' failed.Ĭrash also happens when starting in windowed mode and switching to fullscreen. Starting in windowed mode, and switching to fullscreen works fine. Note that unlike with the SDL1 version, Alt-TAB will show the DOSBox-X SDL2 process. It is possible to use Alt-TAB to switch to another process and use SIGKILL ( killall -9 dosbox-x) on dosbox-x (a normal SIGTERM does nothing, so the process is not responding). Starting DOSBox-X in either windowed mode and switching to fullscreen, or directly starting in fullscreen results in a momentary flash with some white and then a black screen. Seems to work fine, either starting directly in fullscreen, or starting in windowed mode and switching to fullscreen afterwards. To close DOSBox-X you need to use Alt-TAB to highlight the originating process (hopefully a terminal) and send it a SIGTERM with CTRL-C. Also the processes shown by Alt-TAB will not include DOSBox-X. It is possible to press Alt-TAB in this state and switch input focus to another window, but the selected window will not appear (z-order issue?). Pressing CTRL-C will terminate dosbox-x gracefully. Any characters typed end up at the terminal. So if you start it from a terminal, the terminal gets (or keeps?) the input focus, even though you have a full screen DOSBox-X in front of you. set fullscreen=true) causes the keyboard focus to go to the originating process. But starting directly in fullscreen (e.g. Starting DOSBox-X in windowed mode and switching to fullscreen works fine. None of this seems to be dependant on the output= setting, or any other settings for that matter. There are several behaviours that you can encounter.
