hm...game is not tile based and not scrolling...so there will be no chance to find the whole map in memory...
I had a quick look at the "tiles".They have different widths...that makes it to difficult to rip everything in one rush.
another problem is that it works as single screen game...which means no scolling...that is the reason why Rick Dangerous still have no maps in HOL entry. maybe each screen is stored in memory..if it is tilebased...!!
even if they can be ripped it is a painful job to put them together by hand...
Sorry...maybe another one might have a solution....
