if you're into weird #MSDOS games, the Dos Game Jam community put together a compilation 'Demo Disc' with hundreds of megabytes of #DOS games and software, all presented with an authentic super menu by thp and friends. Includes a few of my dos #gamedev jam entries 😎

if you're unsure how to run this, I'm happy to answer any questions. Unpack the 7z archive with 7zip, then drag the resulting iso onto your dosbox shortcut to automatically start dosbox with the 'CD' in drive D. Then type

d:
start

to run the demo disc menu 🌠

@voxel That’s brilliant! :)

I probably haven’t burned a CD since 2007 or so and given the hardware I have DOSBox with a retro filter would look *more* authentic (if you used to connect your PC to a bad TV anyway) than just straight up booting it…

@anjune @voxel do you maybe have recommendations for some good, reasonably accurate filter set & settings, that would be easy to apply for a newbie? When I tried to explore this topic once in some emulator, I got completely overwhelmed... :'/

@akavel @anjune I usually play without filters, the more important part for me is to try and keep the aspect ratio accurate with a 4:3 window instead of stretching it across a wide-screen monitor. That said, if you're using windows this is a really nice filtered version of dosbox https://mattiasgustavsson.itch.io/dosbox-crt

@voxel @akavel Much closer to what it actually looked like, but then I don’t have nostalgic feelings for EGA and VGA and enjoy making them look like something from a(n even) more lo-tech universe.

@voxel @akavel it is beyond me why so many emulators stretch the picture by default. who wants that?!

@akavel

I just use DOSbox filters. I don’t know anything about external shaders

[sdl]
fullscreen = true
fulldouble = false
fullresolution = 0x0
output = opengl

[render]
glshader = rgb3x
aspect = true
scaler = rgb3x

(Don’t remove the *other* key=value pairs in the dosbox config)

@akavel And that will definitely rough the picture up a lot. I’ve never actually seen DOS look like that. But, as I’ve never found PC/DOS video crunchy and delicious enough, it really works for me. Sometimes I’d like to emulate an amber or green screen with nice phosphor afterglow but I haven’t figured that one out yet.

PS: Only seems to take effect at low resolutions like 320x240.
