Ok, so I installed version 5.29 in Mapsource, now I need to change the TYP file. There is a "help.txt" file that reads the following:

1. copy original image "MAP Original" folder (only one image) -- Question: which image file of all? in the installation folder there are 280 .img files. Do we have to do step #1 for every image, one at a time?
2. copy .typ file same directory with "Change TYP File.exe" (only one typ file)
3. doublepress "Change TYP File.exe"
4. the changed image would be found in a directory named "MAP new TYP" (the original would be untouched)
