Simple Launcher v3.6.0 is released. Simple Launcher is an emulator frontend that makes playing retro games a breeze.

Simple Launcher v3.6.0 Changelog:
I performed a major refactoring of the EditSystem class to implement better validation in the input fields of the EditSystem window. This was necessary to prevent users from entering incorrect values.
I improved the system validation mechanism of the system.xml file when 'Simple Launcher' loads. Instead of warning the user about a corrupted file and shutting down the application, it will now remove any corrupted systems, alert the user, and preserve the well-formatted systems. This is useful in case of a corrupted system.xml file.
I implemented in-memory download and extraction of files as a backup method in case the regular extraction method fails. This was done because some users were encountering extraction errors of newly downloaded files, due to file locks.
Added different versions of the 7z executable for x86 and x64. The extraction method will automatically detect the user environment and use the appropriate executable.
Added code to automatically convert [url formatted text] into real links in the RomHistory window.
Improved the log class to send more debug information to the developer.
Added functionality to delete a game file from within the UI, available in the right-click context menu.
Added functionality to auto-generate image previews for the loaded games. The image file is saved inside the corresponding System Image folder with the correct name, available in the right-click context menu.
Added an image pack for Atari 8-Bit.
Update the emulator links to the latest version.
Bug fixes.
