Downloading maps for Mapthis on a Mac

[ice211]

I'm trying to use Mapthis on my PSP, and think it is fantastic, however I'm finding obtaining/downloading any maps impossible as I don't have a PC... I can't use GMDL as it is PC only and the script for downloading maps doesn't work for me (the png files it downloads are corrupt always....)


Has anyone else on a mac found a way to download maps?

Thanks
