Want to play old DOS games easily on whatever Linux machine you're using? RetroArch now has a new fork named DOSBox Pure and you can give it a test now.
There's various launchers out there and guides for running DOSBox but the simplicity offered by RetroArch for retro stuff is great. Having that same ease of use available for DOSBox sounds pretty fantastic to me. DOSBox Pure has a lot of nifty features too like loading from zip files, mounting from inside zip files, save states and rewinding, controller mapping, cheats support and quite a lot more. It's a nicely advanced fork of the original.
Want to give it a go yourself? You can now, as the Libretro team announced that it's ready for public testing along with a version for desktops and also Raspberry Pi (Arm7) so you could do a little DOSBox gaming easily on your fancy RPi setup - something I will admit I need to now try out.
Installing the test build is a simple case of downloading the correct release build, and then extracting the two files into your cores folder. You can usually find that on Linux somewhere like "/.config/retroarch/cores/". After that it's available to load into RetroArch directly and you can test away.
DOSBox Pure itself can be found on GitHub.
