I'll be borrowing the idea of a cache hidden in the Philippines(status quo ante: GC5W0PA).
The following line contains the final coordinates:
1c4d372889f0[MF1]726ac411b[MF2]5ea3acd90d[MF3]0d69
Wait! something's not right... code like this should be 40 characters long and alpha numeric only.
Oh right, I added some steps in solving this mystery. Some of "Fragments of my Geocaching Memories" are scatered all over Singapore.
You need to collect those memory fragments first to be able to complete the code.
Take the following format into account when calculating the final coordinates.
N00.00.000 E000.00.000
