MedLaunch v0.4.2.0 is released. MedLaunch is a .NET (Windows only) front-end for the excellent Mednafen multi-system emulator. It is developed in C# .NET using the Windows Presentation Foundation (WPF).

MedLaunch Features:
* Responsive GUI that allows for a wide range of monitor resolutions
* No installation required
* Local (SQLite) auto-generated database where all settings are saved
* Built-in games library (with system filters and dynamic search)
* ROM scanner (for games library import)
* Game data (images, manuals etc) scraping
* Automatic ROM detection based on NOINTRO & TOSEC DAT releases (so the games library is auto-populated with year, publisher etc. without having to scrape from an external source)
* Manual import of disk-based games (both single and multiple disk games with auto-m3u playlist generation)
* (Nearly) All Mednafen command line parameters available and configurable
* So far uses only Mednafen command line options (and not local configuration files)
* Per-system configuration options
* Built-in browser control with links to Mednafen help pages
* Built-in static netplay server selection along with the ability to specify a custom Mednafen netplay server to connect to

MedLaunch v0.4.2.0 Changelog:
* Only compatible with version 0.9.42.x of Mednafen (although 0.9.41 will probably still launch games)
* Fixed launcher crash when clicking the 'rescrape game' button if game has not been scraped before
* Changed 'Disks' to 'Discs' in games library menu
* Fixed arbitrary game launch when double-clicking on the games library scrollbars
* Implemented 7zip archive support for non-disc systems (roms are extracted to local cache folder before game launch) - one rom per archive file
* Added new setting to clear rom cache folder on application exit (enabled by default)
* Added an option to open the MedLaunch unhandled exception log (if one if present)
* Merged the 'top-right' title-bar buttons into a new (more standard) 'top-left' dropdown menu system
* Duplicated some of the ROM scanning functions in the top menu
* Added top-menu option to locate and launch a game through the filesystem (bypassing MedLaunch config database options meaning the game launches using the Mednafen config files on-disk)
* Moved hidden debug options to new hidden top-right debug menu (visible in Visual Studio debug-mode only)
* Fixed 'Unscraped Games' filter in games library
* Swapped text boxes that require decimal input for NumericUpDown controls (so that decimal and negative numbers can be entered by hand)
