This has been answered a few times already.
Basically this variable determines the satellite search algorithm.
0 - start from scratch
1 - use previously captured location (would only work if you did not move far from the location captured during prev session (the info is usually dumped in a file in a root of your MS..
2 - use sat positions data - the fastest but would only work if the receiver need to reaquire satellites after a short pause...

I suggest using "1" as your setting...

how to unmark zoom level in GML when is fixed? always i must download zoom 1 :(

Unfortunately all firmwares above 3.03 can't currently be downgraded and so you can't run Mapthis!, and the only official software that can support the device are games like MGS;portable ops, hot shots golf and Sony's official GPS software, which is only available in Japan, and most likely is in Japanese and doesn't include much, if any, worldwide support

If the higher firmwares (anything above 3.03) can be made to run unsigned code (which judging from the current trend seems likely:) ) then you would be able to install a custom firmware and run mapthis

no problem, glad it helped.

I did exactly what in your guide, the sample map works fine with my 3.03OE-C PSP But when I tried to use the map I downloaded from Google Map(with gmdl), the map can not be displayed yes I use'_' before the map name and put the whole folder into system folder in my psp. I just wondering since currently I have not gotten the GPS receiver yet. can I use mapThis as a map viewer? If so, what I did wrong? Any one can help???

If you have MapThis installed in /PSP/GAME/MapThis/, then you should place your maps in /PSP/GAME/MapThis/maps/_YourMapOfSomeCity.
