dosbox for s60 is really a great job, win3.1 or some simple dos application can be totally executed on my cell phone.
The phone for testing is N78.

But i also have a problem. at first,I tried to move the cursor by using navigation key, sure no way I can do that. So i modified the mapper.txt, still not work. Then I tried to figure out what the problem is by simplifying the situation, I changed the (key_y "key 57") into (key_s "key 57") ,simply change y into s, or changed into (key_y "key 55"), but it still functions as original, no correspoding change at all. Then I found no matter how i modified the mapper.txt file, it didn't take any effect. It seems it just followed the internal key mappings built in the dosbox.

I put the mapper.txt in the same folder of the dosbox.conf which is e:\data(also tried c:\data).

so does anybody know what the problem is . or it is a bug or something?
or is there a alternative way to change the mapping?

Thank you in advance!
