Sure it can, but the problem you get into is, not everyone has a 64meg card, also, corruption becomes an issue.
I chose UnleashX as an installer, based on its excellent batch command ability, you can find great tuts under the UnleashX forum on this board.
Evox is also a great dash, but I chose UnleashX for its built in gamesaves manager, and built in text editor <~ great for editing the config.xml in real time.
I try to make these gamesaves ultra little for 2 reasons.
1. Bandwith issues.
2. Avoid corruption
Please feel free in looking to making your own 64 meg gamesave. A great place to start is with a gamesave hack that offers an evox installer, look at the basic layour they used, and improve with your files.
