For a next step, every game target in the config file can be given an "engine=MYENGINE" key-value pair. This way, the right engine plugin can be decided upon right away. If the "engine=" field is missing for a given game, we can just revert to the behavior of the "First Refinement" and automatically update the target in the config file with an "engine" key based on which engine the old behavior detects as correct for the game. | For a next step, every game target in the config file can be given an "engine=MYENGINE" key-value pair.

3) Extra Concerns | |||
------------------------------- | |||
*Currently, starting a game without a config entry is supported. For example, if you type "scummvm monkey2" and have no monkey2 target configured, it will try to locate monkey2 in the current directory. We can't know the engine this way, but we could again fall back to the "First Refinement" behavior. | |||
*To support "--list-games", we can just load every engine individually and add the output to a list. | |||
*For desktop ports and certain other ports (e.g. Dreamcast) where it makes more sense to stick with the old, unmodified model of loading all plugins from the start, we can certainly just retain that old behavior :-). | |||
