Do you want the bad or the good news first?
The good news: The game requires only one block to save
The bad news: The game is saved to nonvolatile only at the beginning of a level (not sure if you need to use the save room, but the save should become visible in the "load game" -screen)
I'm on level 2, so ask for help if you need any :-)
Also check my "CD32 nonvolatile save sizes" thread for information on space requirements for various CD32 games, and feel free to add any missing games
(old thread, but decided to reply anyway)
