Volkov Commander is now open source
Volkov Commander is a small but powerful file manager for DOS. Volkov Commander was originally shareware, but Vsevolod recently released the Volkov Commander source code as open source, using the 2-clause BSD license. You can find the original sources for Volkov Commander 4.05 and Volkov Commander 4.99.09 alpha on Vsevolod V. Volkov's website. Danila Sukharev has also created a VC on GitHub project to archive the sources.
EtherSlip 11.8
If you use EtherSlip to get your DOS system online, developer Michael Brutman has released EtherSlip 11.8, based on EtherSlip 11.7 from the Crynwr packet driver collection. This new version of EtherSlip fixes two bugs: 1. The incorrect MAC address was being set in the simulated Ethernet header. This broke mTCP NetDrive and possibly other programs. 2. The code in EtherSlip that simulates ARP responses has a pointer bug in it. This can cause data corruption or crash your program any time it tries to send an ARP request. Get the updated EtherSlip 11.8 from Michael's Device Driver collection. EtherSlip is open source, under the GNU GPL v1.
Updated SBEMU
DOS-era games expect to use a SoundBlaster or other sound card, which aren't available on modern hardware. Instead, if you run DOS on a modern PC (like a laptop) then you need to emulate a SoundBlaster. That's what SBEMU does: "Emulate Sound Blaster and OPL3 in pure DOS using modern PCI-based (onboard and add-in card) sound cards." DOS developer crazii released a new 1.0.0 beta.rc6 version last week, with new fixes and features, including performance improvements. Find the new release at SBEMU on GitHUb. SBEMU is open source, under the GNU GPL v2 license.
