A patch which enables to find two additional buttons (KEY_POWER is not used anywhere, but may be of interest for some). Bad news: the event IDs for KEY_PLAYBACK and KEY_POWER seem to have been changed starting with r49. Buttons with inverted logic are marked with "inv". I have tested this on several DryOS dumps and it seems to have caught the known abnormalities (i.e. the inverted buttons of A490/495/800).
Needs work on r49+ (is inverted state still marked the same way, what are the new events for the playback (and power) buttons).
