This goes for every release. Once you make a save and it makes a file on the VMU, please turn the dreamcast off the first time. From then on, all data is saved. If you save first and keep playing, it will crash. This is not a bug, just how I got this to work the way I needed. Please take this into account when reporting that the game crashed, as I have tested at least one complete playthrough of each game.

All games you have to save make a save on the VMU.
first time on any game you get the chance and it asks you to save
Go ahead and do that. Have enff free blocks on the VMU, etc.
Once a virtual memory card is setup on the VMU, it will
have your progress for all games, and you can load your data.
and it will ask auto; this is key as the first time it saves makes
the file, you have to powercycle the dreamcast and reload your
game, you only have to do this one time when you have never
made a save game if you don't, the game will crash and hang on every
game this not bug at all and it needs to be like this so the
emulator knows you have a memory card.
