I've just got the game as part of MacHeist, and I really like it.

However, I am struggling with the controls as I can't invert the y-axis on the mouse.

I've tried editing the input_preferences.txt file from within main.dat, but I can't seem to get any changes to be recognised.

I've extracted main.dat, and now got a data directory inside Resources. If I leave main.dat in place, then the game doesn't seem to use the information in the 'data' directory. If I remove the main.dat file, then the game crashes at startup with the following:

I've truncated the crash log, as thread 1 is where we are crashing.

Does anyone know of a working method by which I can invert the y-axis on the mouse?

Could this be added as an option under settings?

Thanks,

Bagpuss.

I do not currently know of any way to invert the y-axis on the mouse. There is no edit to input_preferences.txt that I know of that makes this possible. As to the crash, Multiwinia will crash if any of the data files are not present. If you feel the need to hack the data files, you need to leave the originals in place, put the data/ directory in the right place, and make sure that you maintain the structure of the data/ directory. As I have said before, any such hacking will break Multiwinia's auto-updater, and is not supported by Ambrosia. Thus, in terms of hacking the data files, you are largely on your own. If it works, great. If not, there is not a lot that I can do to help you. If you require additional advice or help, you might try asking on the Introversion forums.
