The XLookupString looks like the ascii for the character/digit.  The  
keycode does seem like what you want.  Googling "linux remap keycodes"  
should be a good start, but it looks like xmodmap is proabably what you  
want to use.  However, you also need to know the keycode of the key you  
want to remap.  Essentially, you need to remap whatever keycode your  
current keyboard is generating to that which the game expects for that  
key.  I'm not at all familiar with either program beyond browsing a few  
Google results, but perhaps setxkbmap is used for a major remap of  
most/all keys on a keyboard and xmodmap can be used for single or a  
small number of keys.
