Launcher application for games/apps using the chat API. This should be
|
||||
run by the user and it will start the actual game executable. If a patch
|
||||
file has been downloaded the patch will be applied before starting the game.
|
||||
|
||||
This does not download patches or do version checks, the game/app is responsible
|
||||
for that. This just applies patches that are in the correct location for the
|
||||
game. All patches should be in the "Patches" folder of the app.
|
||||
|
||||
The launcher should have a config file (launcher.cfg) so it knows which apps
|
||||
should be checked for patches. The file should look like this:
|
||||
|
||||
# comment
|
||||
# RUN = the game to launch
|
||||
RUN = . notepad.exe # directory and app name
|
||||
#
|
||||
# Sku's to check for patches
|
||||
#
|
||||
SKU1 = 1100 SOFTWARE\Westwood\WOnline # skus and registry keys
|
||||
SKU2 = 1234 SOFTWARE\Westwood\FakeGame
