I have a Dell Chromebook 11 and I've used DOSbox for a myriad of games for well over a year and it's worked great — up until a Chrome OS update about a month ago. Now, if I maximize the DOSBox window, the game stays its original, small size and the rest of the window is black space. I've tried playing around with my conf file, but everything I've tried so far either doesn't help or it makes DOSBox crash at startup. Here's what it looks like right now:
DOSBox configuration file
[sdl]
output=overlay
[cpu]
core=normal
cycles=auto
If you have any suggestions, please let me know. I'm really at the end of my rope here, I've asked on multiple different forums, but I can barely get any answers. I just want to play some Nethack in a maximized window. Thank you for your help!

As for as I know, DOSBox shouldn't even let you resize the window, just toggle fullscreen on and off.

Where did you get DOSBox from?

What's fullresolution= and windowresolution= set to?

I'm confused by what you're saying here. Do you run DOSBox fullscreen or a maximized window?

fullresolution= and windowresolution= aren't in my conf file. My conf file only contains what I mentioned in my first post. When I try adding the fullresolution= and windowresolution= settings to the conf file, they don't create any noticeable changes when I attempt to maximize the window. I tried all possible settings mentioned on the wiki (i.e original, desktop and 1366x768, the resolution of a Dell Chromebook 11), but none seem to affect the window size or resolution.

My problem is that I like running DOSBox on a maximized window, and it worked fine until a recent ChromeOS update. I used to have output= set to opengl, but since that ChromeOS update, if the conf file is set to output=opengl, then DOSBox shows up as a blank black screen.

The Chromebook version of DOSBox allows you to maximize the window. I got DOSBox from the Chrome store.

Don't even bother. For what I've read in the comments, they say that the app is buggy and stuff like that. This forums are for official ports of DOSBox. Ask the author.

Just another user that likes old OSes and videogames, nothing interesting to see here...

I'm wondering if it was a combination of a driver update, browser update\Native Client update that may or may not require the app to be updated?

According to the changelog it mentions adding Opengl for scalable output implying any other output is not scalable.

It looks like there's a Nethack app for ChromeOS dunno how it compares to the DOS ver.

Do you know if there's a way to get OpenGL drivers for a Chromebook? I was checking the support page under the Chrome app, and this seems to be a common problem with this update of the ChromeOS.
