A very simple control system for an infuriating but excellent game, so a fairly simple overlay.
The GOG version also comes with Jack in the Dark, so there’s a trimmed version for that.

Jack in the Dark

This version :
– toggle a transparent game pad, plus extra arrows for forward+turn
– a Run toggle key (cos it’s a pain to get character to actually run in the game)
– Green keys prime the standard non-inventory item actions
– Top green key with white text toggles between the default House and Underground actions
– Red key performs all selected actions (hit, open, search, jump etc)
– Black buttons send ESC, Enter

This one the green keys do the stated action.

Running :
– Even in the original game with a keyboard running was a bit tricky.
– Run button sends correctly timed keystrokes and changes button appearance to show Run is enabled
– Character runs until stopped, use the left / right arrows to turn while running (not forward arrows).
– Tap Run again to stop
Running means the up arrow is being sent permanently to the DOS game, so if you find an object and get a dialog or just open up the menu you’ll need to stop running to be able to interact with it.

This also works for Alone in the Dark 2, but the green actions will need either editting or removing as they are different.
