I'm not a (dosbox) developer, but anyway 😀
You are aware that there are numerous, way more than for apple's platform, gui frontends for dosbox, right? Have you tried some of them? I'm sure one will suit your needs, there are literally dozens of them. Or perhaps someone who has used boxed can recommend right away one that resembles it...

Doesn't seem like it would be too hard to implement, but from what I can determine about Boxer, it would require creating a fair database of information and patches, etc. for a huge number of games. While not technically difficult, it would take a lot of work and research to do. You would also have to have all of those games for testing.

I might consider doing a menu application similar to Boxer that my installers could populate, but it would be limited to just the games that I have written installers. Of course I am integrating support to add the games to the Games Explorer via my installers. Functionally this would not be that much different than games that have been added to the Boxer app.

You don't need to be a fanboy to use a Mac. At least, I don't feel like. It's just a workplace.

As for OS X DOSBox frontends recommended above, most of them are out of date, created for pre-0.70 versions.

The OP looks for Windows frontends I think 😉

I love the look of Boxer and GOG.com's game shelves too but I'm mainly a Windows user. I've been looking for a front-end with similar look and feel to use with video games and my eBook collections but I guess it can't be compiled on Windows because it feels like (just speculating) graphics libraries used by the Boxer are Mac-specific

The thing with Boxer is that it's just a frontend\offshoot of DOSBox so the hard work was already done.

The DOSBox devs are interested in making DOS games work which is the most important part.

Is Boxer so superior to DBGL and DFend that you can't use those?

Also:

"Boxer takes your CDs, floppies and bootleg game copies and wraps them into app-style gameboxes you just click to play. They’re self-contained so you can back them up or share them with friends. No mess, no fuss."

Even if/when DOSBox has a included GUI similar to the above you won't be seeing it promoting sharing them with your "friends" or any functionality that would potentially contribute to that....

As I said before the concept is simple, but to make it work with legitimate copies would take developing a very large database of games, versions, patches and box shots. Here is a proof of concept with a number of shortcuts taken for brevity. All of these would have to be replaced. It does not have drag and drop to add games enabled. It has a few demo games hardwired into it. The box shots would need to be refined to give a more 3D look/drop shadow, etc. The background image is just from the GOG game shelf and would need to be replaced if this were a real project. Again it is just to show how simple the concept is.

OK, if it was about the looks I found something
