I've been wasting time lately on a super old school game called Executive Suite.

I suggest that anyone should give this a try, at least once if not more.

Only problem running this is with Xkbd.

For the Enter key, for whatever Xkbd that you have, using Emelfm2 change the following output from

default Enter
default_ks KP_Enter

to

default Enter
default_ks Return

Actually, whatever keyboard you're using should have been given the value Return as opposed to KP_Enter anyway.

The only reason why I didn't go with Return was because that anything, other than Dosbox, this pulls up the Hildon Keyboard.

For a more simpler approach, you can just click on the center D-Pad and that would do the trick as well.

Anyway, for more on Executive Suite and how to download it freely, I found it over at this page:
