Hi
I got a first version of the games plugin working. Maybe someone with
more knowledge about Freevo 2.0 takes a look at it and tels me what i
should improve.
I didn't write it as a MediaItem since i saw know way this would fit.
There are two different game plugins at the moment the emulator plugin,
this should work for most of the emulators (i have only tested with
zsnes, but since it just calls an emulator with the parameters it should
work with others). The second plugin is for PcGames with this it is
possible to run usual games.
What i would like to add would be a plugin for the scummvm, it will not
work with the emulator plugin, since the scummvm does not needs one rom
file. But this should be easily possible with the current structure.
What i think isn't done very well is the EmulatorMenuItem (emulator.py)
since this is almost the same as MediaMenu but i couldn't get MediaMenu
to do what i wanted, so i copied it and changed it a bit.
I hope i haven't done to many things the wrong way, since the
architecture of Freevo 2.0 isn't that easy to get through.
Thanks
Mathias
