When joining the subfiles with GMapTool, I've added " - LITE" to the mapset name, which was too many, so GMapTool truncated the string.

Well, it was expected. You know, new bitstream formats, etc.
Wanna try pseudo-NT maps? They look like regular NT, but have "map created with cgpsmapper" string somewhere in copyrights in GMapTool's dump.

In pseudo-NT and NT maps data is stored inside GMP subfiles, unlike non-NT maps, where old good map subfiles are present separately (RGN, LBL, NET, ...).
The difference between pseudo-NT and NT is how the map data is encoded: NT uses new encoding which is unknown to old devices, pseudo-NT uses old encoding.
We can read pseudo-NT with mapedit, but we can't read NT (only points without addresses are loaded).
