Features:
Easy to Add files

Easy to save and load configurations

DOSBox support

Note that it is recommended that your path to your original Doom executable and additional pwads contain no directory names longer than 8 characters, as this is the form DOS expects - additionally, the original executable can only load the IWAD contained in its folder, rather than the one you selected.
Extended Engine customization

Open doom files with Rocket Launcher 2.0 and let it be your middle man
If you're opening a new wad file, whether from your desktop file explorer or directly from a download, be sure to associate *.wad and *.pk3 files with Rocket Launcher 2.0, so that you can always quickly choose which engine and launch options you want to run the file with, and add any additional files or resources as needed. You can even drag multiple files at once onto Rocket Launcher 2.0 and they will all be ready loaded!
Qt Framework
This allows for this project to be cross platform, including support for Linux and OSX. For windows I provide a static build, which means it's provided as a single executable with no additional DLL's required or frameworks to install.
