For those not comfortable with using the DOS command-line interface of ScummVM, here's the solution you're looking for. Simply choose the options you want, and the loader will send them off to the command-line for you.
The loader uses an easily updated list of currently supported games to provide the Game List.
This is a work-in-progress version, so (for now) be sure to put the loader in the same directory as
SCUMMVM.EXE
. I'm adding the ability to configure the loader as well as save per-game settings.
