I’ve just tried out both tools to find out something about the save games, but with the game I tested (Unterwegs in Düsterburg), RPG_RT.exe says “Stream error” and exits, when I try to load even an unmodified savegame, which I ran
lsd2xml and then xml2lsd on.
I created the savegame just after starting a new game.
Output:

(looks like it got stuck at common_events?)
The filesize is different:
original .lsd file: 8kb,
generated .lsd file: 7kb
Here are the original save file, the one generated by xml2lsd and the generated xml file:

I hope this helps 
Thanks for developing easyrpg! 
PS: I was using the lsd2xml.zip from that blog entry.
EDIT: Slightly offtopic, but is there a way to download the lastest Player build from the jenkins server? I can’t find a download link.
