ok let me sum this up.. follow closely and it will work
1. name ur folder in all UPPER CASE eg. _MELBOURNE
2. start mapthis! -> select a map -> go to config
3. scroll down till the >> is on STARTUPMAP
4. press X to edit..
5 delete the whole map name ie. whatever is after the _ eg. MELBOURNE for my case
6 type it in using mapthis! again.
7 press start to save. NEXT STEP IS IMPORTANT!!
8 press X to edit again to check the flashing _ is ON the last charater and not after it. if not follow all of step 9 else skip step 9
9.1. if it is after the last character, press triangle to delete it.
9.2. press start to save it
9.3. click on X again to check if the flashing _ is ON the last character (it should be now)
10. restart mapthis! it should work now.
beside being case sensitive, there is a problem of carriage return (CR) and line feed (LF) between mapthis! and notepad/wordpad. ok it doesn't really matter now. just make sure u dun use notepad/wordpad to edit anything.
*to 100% confirm that it is working, open using NOTEPAD but dun save anything. u will see
STARTUPMAP=_MELBOURNE############################# #####################
all in one line
but in mapthis! config, it will be seperated.
hope its clearer now!
