  Re: Maemo Mapper Mod - the new map file format
  
  That's basically what I did. I never download maps using N800 actually, all my map tiles downloading, poi...are managed on PC. But even that, MM2.x can not be comparable with MM1.4 in the speed.

  Re: Maemo Mapper Mod - the new map file format
  
  That's probably one of the issue panning is slow. Even you downloading couple of tiles, it does a sync, which I really don't like.

  Re: Maemo Mapper Mod - the new map file format

  That's what I mean, the number of writing, but has to be to the same location.
  
  The GDBM uses default allocation unit size as the hash table(bucket) size, normally it's 32k on a SDHC card.

  There is a 4 level difference between the two map formats. In MM2.x level 6 corresponds to level 2 in MM1.x, so you need to have map tiles in MM1.x repository of level 2 and under to have them shown...

  Winmapper stores the map tiles in MM1.x format, which is not compatible with MM2.x that you're using.
