OK, i’m using an iPad. But testing it on my other "normal" PC, i’ve got the same problem. The game, posted above, has defined keys which cannot be configured. I want to map them to the usual MAME-keys. Rapid fire is no option, because the game reacts different, when you firing rapidly or holding fire down. When i use the GameEx advanced config editor and holding the firebutton pressed, the witch fires for a few seconds and stops firering then. Using the original keys, the whitch fires permanently while holding fire down.
