Just take a look at Kevin's bank-switching document at:

I believe it has all the information you'll need about the 
3F bank-switching scheme.  The original Tigervision method only
used 4 2K slices with made it an 8K cart.  However, if you use all
8 bits of 3F then you could have 256 2K slices for a total of
512K.  The latest version of Stella should support 3F carts of
up to 512K so if you need the space it's their (I believe PCAE
supports this as well).

Hopefully, Stella will support the Megacart in the final 1.0
release.  If you'd like to use it then let me know and I'll 
bump it up on the priority list.
