Commonly, you’re going to either notice the game’s having trouble refreshing the display (leading to a number of hangups), or simply crash altogether. Troubleshooting Display Issuesĭue to the difference between older computer screens and modern screens, it’s fairly common for DOSBox virtualization to experience a few display issues here and there. Consider what other programs are running when you open the emulator.
If, even with all of the above, you’re still running into frame rate issues, it may well be that your system’s having trouble running DOSBox due to a lack of computing resources. Again, you can change all of this by editing the configuration file (DOSBox Options) as well. Simply type either frame-skip 1 or frame-skip 2. Once you’ve figured out the ‘sweet spot’ for a particular game, you can open up the DOSBox configuration file, and change DOSBox’s configuration file by opening up “Options” in the DOSBox folder, and changing the value you see next to “cycles.”Īlternatively, you can simply keep track of which games require different CPU speeds, and enter in the command “cycles=(value you’re setting the cycles to).” Finally, you can try enabling frame-skip. There are a few ways you can do this- first and foremost, you can try changing the core affinity of either DosBox or the game you’re trying to run to a single processor on multi-core systems. In order to keep a game’s frame-rate at a level that’s manageable for the application, you’re basically going to need to tone down the power of your system.
There are a number of reasons that this might happen, but usually it’s because your system is displaying a frame-rate that’s too high for the game to handle- as a result, you get chopping, skipping, and generally poor image quality. Most commonly, you’re going to see some frame-rate issues and graphical glitches. If you’re downloading DOSBox, it’s worth a read.Īnyway, as is the case with most applications- particularly emulation platforms- DOSBox doesn’t work perfectly all the time.
#DOSBOX OPTIONS INSTALL#
Oh, and you should probably give yourself a refresher course on MS-DOS commands- there’s a tutorial notepad file included with the DOSBox install file.
