Black screen when opening a game

[randycool279]

I have a problem everytime when I try to run a game like Doom. It shrinks up and freezes, not able to fix it...

Maybe problem in emulator? Maybe it can't emulate all the features of real hardware.

Same here, running this on a Ubuntu 18.10 on Wayland.

Dang was hoping to play Wolf3D but it's just black for me as well. Latest macOS.

I assume this doesn't emulate well enough for games. You would be much better off with Virtualbox/PCem/VMWare

PCem is the most authentic since it emulates the old hardware too.

Same issue here, except I havent even TRIED opening doom, just the friggin' readme.

reminds me of #50 a little bit, I think this is caused by the application not detecting the abrupt resolution change to MS-DOS that well.

on the readme.md, there's a link to a video which shows it's recommended to use Doom 95 (a little known version of doom made for windows 95) and 640x480 in 256-colors.

Same here Ubuntu, HP. When i closed it. And reopened it it wouldn't load

If you wait enough time after loading anything doing with DOS, you'll notice that it will start to respond on that mess of a screen, yet very slowly. If you have the patience, you can get the mouse to those garbled pixels, and you'd see it fine. So You can manage to reboot the machine after waiting a while, and that bug will temporarily no longer happen (as when you restore the snapshot, restore the machine, or hard reboot/shutdown the machine, the bug will happen again). It must be some sort of problem while booting up I'm guessing?

This is MS-DOS Promlem #50
Try to run MS-DOS in fullscreen and start doom from it. (not tested)
Or boot from scratch and spam F8 to open boot menu, then choose cmd prompt only and do same
