Nice! I tried it out and have written an Email some minutes ago, because there is still a problem left, with level-names that have special-characters included, when these files were copied in a folder on the PC harddrive. Solution is simple, i wrote everyting in the Email, please have a look.

Yes, this finally worked. Download version 1.4 here, look into the SD2IEC folder and there you will find a "file version" of the game, that has all 435 single game-files directly into one folder. Simply copy this folder to the SD-Card of your SD2IEC and start the "!entrance" file there, for example with a filebrowser. Then you can play the game on the SD2IEC without the need, to change disksides.
