Custom launch options

[MobyGamer]

TDL needs a way for people to manually specify a launch command-line. This will not come into practice very much, but there are cases where it would be sorely needed, for when you want to force use of a particular graphics or sound standard that can only be specified on the command-line.

Tentative idea is to allow power-users the ability to use ctrl-enter which will bring up an editing line. Entered options should persist; maybe a file that uses the titleid+exename+cmdline in fixed-length records.

Undetermined:

• Should custom command-line be honored only when hitting ctrl-enter, or all the time?

This is low priority.
